Ci provo: i due tavoli sono effettivamente uguali per quanto riguarda il 
piano. Ciň che illude e crea il senso di differenza č la posizione delle 
gambe che fanno sembrare piů tozzo quello a destra e piů slanciato quello a 
sinistra. Inoltre c'č anche un gioco di prospettiva credo, basato sul fatto 
che il tavolo messo in verticale ci appare naturalmente piů slanciato e 
lungo rispetto a quello in orizzontale.
Ci ho provato. :)

La lente dell'obiettivo ha un effetto deformante che allunga in verticale e
accorcia in orizzontale.
L'effetto riguarda tanto i tavoli disegnati quanto il pezzo di carta... e
tutto quadra.
Purtroppo perň lo stesso effetto č visibile anche sulla mano
Provate a concentrare l'attenzione sulla forma dell'indice, nella parte piů
lontana dall'obiettivo (dove l'effetto č piů accentuato). Per quanto il
tizio tenti di mantenere costante l'orientamento delle dita, non ci riesce
del tutto e quando spinge il foglietto di carta sul tavolo disposto in
verticale il suo dito diventa uno spinello lungo e sottile ;-)
Io almeno vedo questo... poi non so...

 Io almeno vedo questo... poi non so...
Non mi sembra che ci siano lenti deformanti, perche' si puo' provare
con un foglietto sul monitor, oppure riproducendo il disegno su un
foglio.
Credo che la lente deformante sia il nostro cervello, che vede oggetti
3d in un disegno 2d.

Sì, ho verificato e hai pienamente ragione!
Solo illusione ottica!!! 

 lungo rispetto a quello in orizzontale.
Leva pure il "credo", è proprio un gioco di prospettiva: il piano su
cui è appoggiato il disegno è inclinato rispetto alla telecamera, e tu
ne vedi quindi una proiezione deformata per cui la parte del disegno
più "lontana" è rimpicciolita rispetto a quella più "vicina".

Grazie del suggerimento

prostitution in most
cases for a living." During 1869, one poor woman signed a bond to
deport herself for five years rather than be taken to the Lock
Hospital. But the "protected women," with their nursery of children
they were raising for brothel slavery, being the mistresses of
foreigners, were not persecuted in this manner, so, by a kind of mad
infatuation the Government seemed bent on encouraging and developing
immoral women and driving decent women either into prostitution, or,
by the reign of terror, out of the Colony. In 1869, five women
were charged before the Registrar General, and three of them were
discharged as innocent. Then the Registrar General decided _to make
the punishment of the first of the remaining two depend upon the state
of health of the second_. This second was examined and found diseased,
and in consequence of that fact, the first one was fined fifty dollars
or two months' imprisonment! The Commission speaks of this as a
"somewhat curious" case. We wonder how the punished woman described
it. Afterwards, the case was reopened, and "evidence was given
calculated to throw the gravest doubts on the credibility of the
informers" against these five women. What was then done? Were the
informers punished for giving false evidence designed to work
incalculable injury to five

testimony from this
time forward was well-nigh universal in Hong Kong circles that
domestic slavery, or "domestic servitude," as Dr. Eitel recommended
that it should be called instead (since a weed by another name
may help the imagination to think it a rose), was very "mild" and
"harmless," and that the adoption of purchased boys was a "religious"
duty, or at least, had a religious flavor about it, as practiced by
the Chinese. But as we have already said, that adoption in order to be
lawful in China must be the adoption of one of the same surname.
On October 27th, 1879, the Chief Justice, at an adjourned sitting
of the Court for the purpose, sentenced two more offenders, one for
kidnaping a boy, and the other for detaining a girl with intent to
sell her. In the first case the Judge said:
    "Received as you had been into the father's house in charity, you
    availed yourself of the opportunity to steal his child, and tried
    to sell the child openly, probably having hawked him from door to
    door. The sentence of the Court on you, Tang Atim, is that you be
    imprisoned and kept to hard labor for two years, and that you be
    kept in solitary confinement for a period of one week in every two
    months of your imprisonment."
Chan Achit, an old woman, convicted of having unlawfully detained a
female child of 11 years of age, with intent to sell her, was next
placed in the dock. His Lordship said:
    "The evidence in this case has shown the extraordinary extent to
    which, under cloak of China custom, the iniquity of dealing in
    children has extended. From the evidence, I have no doubt that a
    vagabond clansman to whom the father had occasionally given out of
 

child. He adds:
    "The woman was merely a middle woman, and received a small sum,
    but it came out in the evidence that Leung A-Luk had bought the
    child for $53, and was actually confining her in a room where
    the child was discovered. She was the great criminal. It is an
    opprobrium to justice to punish this poor woman, and to allow
    Leung A-Luk to go unpunished. I am aware that, according to
    precedents here and at home, it is within the province of the
    presiding judge to direct prosecutions such as these to be
    instituted, but I think it more convenient to ask His Excellency,
    as the head of the Executive (whose province it especially is to
    originate criminal proceedings) to direct prosecution. To let
    these chief offenders go unprosecuted, and to punish such
    miserable creatures, exposes the court to the contempt of the
    community, and tends to destroy all respect for the administration
    of justice in the Chinese community."
Accordingly the Governor forwarded this request on the part of the
Chief Justice to the Attorney General, saying: "It is clear from the
evidence and from documents published by the Contagious Diseases
Commission that practices of this kind have prevailed unchecked, or
almost unchecked, for many years past in this Colony." The Governor
then referred to a case in point that he had submitted to the former
Attorney G

had sent them, and would like to send a good many more,
when they were very ill. He told us of going over the records, for
years back, and of finding that the average of time spent in the
brothel by these girls was three years and a half, while, if they
stayed in Canton, they would be life-long prostitutes. He made much
of this point, and argued that it was better for them to come
to Singapore in order to be set free by the Protectorate, but
acknowledged that many of them became concubines (in "following a
man," as the Chinese express it). He spoke of domestic slavery in
Singapore, but declared it was slavery of a very mild sort. We asked
who came with the Chinese girls when they came to the Protectorate.
He answered, "Oh, a friend--the woman or 'mother' who owns them." We
asked if nothing could be done against these traffickers in girls; he
said they could not often get sufficient proof against them. We saw in
one of the records something about "women traffickers," and pressed
him to know why 

China to the brothel-keepers' confederates. In many cases
    girls are thus sold by their parents for the payment of gambling
    and other debts, and sometimes, alas, to provide money for the
    purchase of opium. Surely it is a burning shame that British
    Colonies should have become the market for the sale of Chinese
    women into this diabolical form of slavery.
    This article cannot be closed without a brief reference to another
    and more subtle form of slavery which is well known to exist in
    the Straits. The last Report of the Chinese Protectorate reveals
    the fact that during last year (1892) in Singapore alone 426
    prostitutes left brothels and went into private houses, and in
    the same period 148 left private houses and entered brothels. The
    wealthy Chinese in the Straits Settlements keep up very large
    establishments, and the uninitiated visitor cannot fail to be
    surprised at the number of young women in the quarter assigned
    to the servants. They are employed on house work, and keep the
    magnificent furniture and wardrobes in splendid order, and in many
    cases they make cakes and sweetmeats which are sold on the streets
    by their own offspring. The question naturally arises,--Are these
    women and girls free agents? It is very difficult to say with
    certainty whether they are free or not, but it is generally
    admitted that a subtle form of domestic slavery does exist in the
    Straits, and that boys as well as girls are bought and sold with
    impunity.
    This account in no way exaggerates conditions, as official
    documents plainly show. We will confine our thoughts, however,
    to the women. In a plea for the continuance of the Contagious
    Diseases Ordinance at Singapore, Mr. Pickering, "Protector,"
    describes two classes of prostitutes, a proportion of free women
    "who come down her

the thing was by express
    law illegal. I go further, and I find that the penal law of China,
    whilst it facilitates the adoption of children into a family to
    keep up its succession, prohibits by section 78 the receiving into
    his house by any one of a person of a different surname, declaring
    him guilty of 'confounding family distinctions,' and punishing him
    with 60 blows; the father of the son who shall 'give away' ... his
    son is to be subject to the same punishment. Again, section 79
    enacts that whosoever shall receive and detain the strayed or lost
    child of a respectable person, and, instead of taking it before
    the magistrate, sell such child as a slave, shall be punished by
    100 blows and three years' banishment. Whosoever shall sell such
    child for marriage or adoption into any family as son or grandson
    shall be punished with 90 blows and banishment for two years and
    a half. Whosoever shall dispose of a strayed or lost slave shall
    suffer the punishment provided by the law reduced one degree. If
    any person shall receive or detain a fugitive child, and, instead
    of taking it before the magistrate, sell such child for a slave,
    he shall be punished by 90 blows and banishment for two years and
    a half. Whosoever shall sell any such fugitive child for marriage
    or adoption shall suffer the punishment of 80 blows and two years'
    banishment.... Whosoever shall detain for his own use as a slave,
    wife, or child, any such lost, strayed or fugitive child or slave,
    shall be equally liable to be punished as above mentioned, but if
    only guilty of detaining the same for a short time the punishment
    shall not exceed 80 blows. When the purchaser or the negotiator of
    the purchase shall be aware of the unlawfulness of the transaction
    he shall suffer punishment one degree less than 

painful meaning to her.
Our hearts grew heavier and heavier as we talked together. The
Matron, said: "Why, I thought when I came here it was to do a regular
Christian work for these girls. That was my purpose, but the more I
inquire into the matter, and study over the things I am expected to do
and ask no questions, such as sending girls over to the Lock Hospital
at the Chief Inspector's request, the more I feel that I am being
worked for purposes of which I cannot approve. I cannot stay here."
At last we got to ask her about her talk with the Inspector. "What
did he say when you told him what we discovered the other night--that
little girls go freely to the Licensed Eating Houses, and live in the
brothels?" "Is it really true that the authorities have been deceived,
and did not know of this flagrant violation of the Ordinance to
protect women and girls?"
The Matron's face was sadly troubled. She gazed at us a moment
quietly, and then said:
"He told me, Why, of course he knew about those children. There were
scores of them."
"But will he do nothing about the matter?" we exclaimed.
She replied: "He said: 'What can I do? I caught a whole handful
of them once and sent them to the Lock Hospital, and had them all
examined. The doctor pronounced them all virgins, so I could do
nothing as yet, and I let them all go back.'"
We uttered exclamations of horror.
"A handful!"--did he think no more of them than of so many minnows!
And they had gone through the horrible ordeal at the Lock Hosp

told our hostess one day that we desired jinrikshas that we might
be conveyed to the Protectorate to interview the Chief Inspector,
having heard that he desired an interview. As we were leaving the
house she detained us a moment to say, timidly: "Ladies, do pardon me,
but I feel I must caution you that that man has a very violent temper,
and it will not do in case you see anything, to criticise,--no matter
what you think. I don't wish to seem to intrude, but I know the man's
reputation as to temper, and I cannot bear to think of his having a
chance to treat you rudely." We thanked her heartily, and promised to
be doubly careful.
We knew the place. A very imposing Government building standing apart
by itself, upon which much money had been expended to give it a fine
appearance. We were soon ushered into the presence of the man who held
the same relation to the work at Singapore that John Lee holds, or at
least held the last we knew, at Hong Kong. Will you believe us, when
we tell you that to our amazement it was that same white-haired old
man to whom we had been introduced at the church gathering as such an
active Christian, "working along much the same lines as ourselves, and
at the head and front of every good work in the Colony?" To be sure we
had heard the name of this Inspector, but we had never in our remotest
conception connected it with the man the Doctor had introduced to us.
Concealing our surprise we sat down for a few moment's interview. The

In pratica dice che le donne cinesi sono tutte molto facili di costumi

Alcune lo fanno per pagarsi l'assicurazione alla bicicletta e altre
per poter pagare la tasse di occupazione del suolo pubblico per far si
che il loro marito possa occupare, per un certo periodo, la fontana
del paese allo scopo di esercitare all'interno di essa alcune
elementari funzioni fisiologiche.
Finisce col dire che questo è un problema del quale dovrebbe occuparsi
