cial muscles, the tendons and aponeuroses, the
nerves, and the veins, and arteries and glands.
The color Of the muscles on the Mannikin, is
that Of raw flesh, which shows strongly In con-
trast with the white aud grey of the ,endons *
nerves, the dark color Of the veins, and the red
Of ,he arteries.
1.-THE preparation had gone no farther, it
wo1ld have been very interesting and instruc-
tive, bu, this is only the beginning. The mus
cles Of the head were FIRST removed one by one,
from the temples, the crown, sc. and thus the
bare Uranium, was exposed. Several sections
Of the brain were presented by removing por-
lions of the scull and its contents, and thus the
external and internal appearance OF the brain
was revealed. The eye was removed, entire,
from its socket; the muscles which gave it mo-
ton, the coats by which i, is invested, the hu-
mors which Fill its cavity (imita,ed in glass; s
the re,ina within, expanded from the optic
nerve, were all exhibited with perfect distinct
ness.
The muscles that invest the neck, the trunk,
the arm aud lower limbs were successfully re-
moved, one by one, and laid upon the table; the
lungs and heart and liver, and the appendages
were taken out, and their structure exhibited.
Every part preserved its form entire, although
separated, and the spoils Of Masnikin were
accumulated upon table, uhtilo one might have
supposed tina, several men had contributed to
form the pile.
Every muscle with its tendons, nerves and
blood vessels was removed, down 10 the very
bones, and when they were again put together,
nothing was wanting nor out Of place, to form
the original figure. The superiority ofthis ar
tti6cial preparation, in some particulars, even
to natural preparations, was pointed out; espe.
ciallv in the muscles, which were Of course in
full dimensions and not shrubk and shrivelled
as in natural specimens. The nature Of the
material is unknown; it is however very firm &
not liable to be broken by handling, nor even
by fall 1t is obvious that his preparation is
most valuable,and interesting acquisition not
only TO the schools of ana my, but as correct
and permanen, chart to guide the course Of the
practising physician and surgeon.
To the general student and man Of merely
liberal education, it is almost sufficient to give
a general idea Of anatomy, and perhaps would
be quite sufficient, with the addition Of the
counterpart, and Of preparations Of particular
organs which require more full development.

ry force they exert, although they are compos-
ed Of such slender threads and 6bres. The fol-
lowing facts in relation 10 this point, are de-
monstraied by the celebrated Boreli, in his De
Motu .4nimalium. When man lifts with his
teeth, a weight Of two hundred pounds, with a
rope fastened TO the jaw teeth, the muscles
named Temporalis and Massetes, with which
rhp,v nd NH ri RI
ert force of above fifty thousand pounds
weight. II any one hanging his arm directly
downwards lifts weight Of twenty pounds with
the third or last jjiat Of his thumb, the muscles
which bends the thumb, and bends that weight,
exerts force of ABOUT three thousand pounds.
When a man, standing upon his feet, leaps or
springs forward to the height Of two feet, if the
weight Of such man be one hundred and fifty
pounds, the muscles employed in that action
will exert force two thousand times greater
that is to say, force of about three hundred
thousand pounds The heart, at each pulse or
contraction, by which it protrudes the blood
out of the arteries into the veins exerts force
of ABOVE hundred thousand pounds.

TED island Oh farOS, 1910.
This Island Is cele braled among the Cyclades,
and is from sixty TO seventy miles in cireum-
ference, possessing in ancient times, rich soil,
and those extensive marble quarries, which have
adorned the labyripths Of Egypt, and enriched
the cities of Greece and Rome. This island is
also celebrated for those marbles, most COM
monty known by the name of .Arundekan, which
informs us Of the most remarkable events in
the early ages Of ancient history, and were FIN
shed near about 244 years B, &. They are yet
to be seen in one Of the institutes Of Paris or
England The island is said to have been first
founded by the Phenecians, who assisted the
Persians in their war against Greeee-from
this cause it was overrun by the .dthenians, and
some time after fell into the hands Of the Ro-
mans.
travelled over the Island, anG found it par
TALLY cultivated in the valies, for the support
of two or three uncomfortable villages. The
remainder OF the island appears to be composed
entirely of marble. visited the quarries said
10 have been worked in ancient times, and found
them very extensive, the marble perfectly white
and transparent, and celebrated among sculp-
tors for its solidi,y. The Apollo Bel,idere,
the Venus de Medicis, and several other beau
,fal pieces of sculpture have have been con-
s,ructed from this quarry We set out before
