Notice of a Manual of Chemistry. 335 
works of general use, will greatly enhance the value of this 
Manual, and render it the more acceptable both to teachers and 
students. The arrangements of apparatus, and the descriptions 
of the figures are unusually full and complete. In the frontis- 
piece we find represented Dr. Charles 'T’. Jackson’s newly in- 
vented oxy-alcohol and air-blast lamp, which possesses great 
power. We also find in the frontispiece a figure of a new air- 
pump of great simplicity and beauty, recently made for Harvard 
College. It was constructed by N. B. Chamberlain, Philosophical 
Instrument Maker, School street, Boston; and we learn from the 
anual that it will freeze water on Teuie's plan, with perfect 
ease and great rapidity. It affords us much pleasure to direct 
attention to this instrument, as we can well remember how ex- 
tremely difficult it was, until within a few years, to get chemical 
and philosophical apparatus of good quality made in this country. 
We were often compelled to forego the pleasure of prosecuting 
our investigations, and of following along the paths newly opened 
by our transatlantic brethren ; to make the essay with inferior 
instruments and the almost. positive knowledge that we should 
in consequence fail ‘of attaining the desired result ; or to lose much 
valuable time and expend much money in ordering the requisite 
instruments from Europe. This difficulty was owing in part, 
undoubtedly, to our artists not having been duly encouraged to 
exert their ingenuity and skill. Dr. Webster informs us that all 
the apparatus figured and described in his work, is or can be made 
y Mr. Chamberlain. As therefore there is no longer any defi- 
ciency of skill or ingenuity upon the part of artists, we trus' ib 
will be nd withholding of patronage upon the part of o ” 
Science ; and most sincerely do we hope, for the aie of | our 
country, that public institutions as well as individuals, will be 
more patriotic than to send abroad for apparatus, when it can be 
So well and so cheaply made under their own inspection at home.* 
We cannot close this notice, without expressing a desire that 
Dr. Webster would abridge his Manual for the use of the higher 
classes of schools and of academies. A good text-book is much 
needed in such seminaries. 
* It is but justice to our excellent artists and to the progress of practical as well 
a8 theoretical science among us to say, that our principal cities now contain estab- 
lishments, in which almost every kind of philosophical apparatus is manufactured 
with ileinnae
