pror. BHAcxrrrs THIRD LECTURE last eye.


ming was attended by very large number of
| interested auditors, notwithstanding the bad
weather. In opening, the Professor, remarked
that during the previous lectures his audience
had found evidence of a new form of force
| We greatly misuse the word. 1t is often con-
founded with velocity or power He preferred
to express its nature by the word energy, as
more generic and comprehensive init charac-
ter. Ii we were to push analysis to the eX-
IRENE we should find force or energy to be con-
nected with time and space. If we consider
| the motion of a mass, or MOLECULES, or atoms,
both time and space must be taken into ac-
count in measuring their movements. The
| groundwork of force is will somewhere, and
if we so find it we shall admit that it is an in
telligence-like that which builds up the crys-
| tails or forms the human eye, and enables us to
| follow out the manipulations of energy. Dia-
magnetism the leading subject of the lecture,
was defined as that force which moves at right
angles to ordinary magnetism. All substances
are magnetic or diamagnetic and all things are
either matter or Unreasonable ether, which we
cannot weigh, and through which the methods
of energy operate. By the use of a couple of
helices the lecturer demonstrated the different
conditions under which magnetism becomes
heat and when it changes to electricity. By
passing current from the battery through the
helices he showed that when the circuit was
opened and closed successfully, the coils at
tracted and repealed metals, and with a NINA
ture engine he illustrated the application of
this force to the driving of machinery. The
science of telegraphy was also fully explained,
by the use OF the apparatus. Prof. Bracket
does not assume, in these lectures, to teach
those who are familiar with the mysteries of
the natural sciences but to make them clear to
the popular mind 1t is gratifying to observe
that they are well attended, but the audiences
are not so large as they should be, for the in
formation impaired by them is interesting and
highly important to all classes.
THAT LETTER.-The letter from Stoneham to
the wealthiest single gentleman in Portland"
which has been so much talked about in the pa
pers, was made the subject of neat little sar-
casm by that inveterate joker who presides at
the Post Office. The Judge selected as his VIC
tim worthy but impecunious young journalist
who filled the bill only in point of being single
gentleman, and insisted that public sentiment
was unanimous that this was the proper des-
tination of the document, which seems to be
the effuson of some gushing school girl in
search of an adventure or some other person
trying rather venerable kind of joke. Here
is the letter in full, and the gentleman to whom
it should have been given can answer at his
leisure:
SToNEHAM, Mass, Oct. 18th, 1872.
Dear Slr,-As you are the richest single gem
tleman now in the place, you of course have
plenty of spare change and also time which
you could improve by sparing little of each to
ayoung lady worthy of your attention. and as
she has no gentleman friends at present, and
Christmas being near, thinks it would be very
pleasant to hang her stocking at the door and
find it full on Christmas morn. Oh! how JOY
GUS it would be to find within my hose a huge
diamond ring bearing within the initials of the
giver's name; just think one moment to your
self would you not like to make one heart glad
on Christmas morn.
In case you would 1 take the liberty to send
You my address, which is
AGNES HEATH,
T. y. Box 217. Stoneham, Mass.
