circumstances far more repulsive than the idea of cremation 
could be. The former gentleman described scenes that he 
had witnessed in Spain, and the method pursued in New 
Orleans; and the latter referred to the celebrated horrors of 
the Campo Santo, at Naples. 
The debate was continued for some time, by Pror. Wurtz, 
Dr. Am Enpg, of Hoboken, and the PRESIDENT, who, in sum- 
ming up the discussion, vindicated its introduction as a 
matter of high scientific interest. 
Pror. T. EGLEesron read an extended paper on “ The An- 
alysis of Furnace Gases,”* describing particularly the Orsat 
apparatus, both as to its mode of working, and its great pro- 
spective value. 
Jt has long been very desirable to have an apparatus for 
the industrial analysis of gases; as none of those that are 
familiarly known fulfil the necessary requisites of simple con- 
struction and rapid operation. Such analyses must be exe- 
cuted quickly, in order to give the key to what is going on; 
so that operations in course of execution may be modified 
or not, according to the indications furnished. 
The Bunsen, Doyere, and Regnault methods cannot, save 
in rare cases, be introduced into industrial establishments ; 
and hence the practice of making gas-analyses, in such quar- 
ters, has been confined to certain special manufactures, 
mainly of recent date, wherein the necessity of analyzing the 
gases has been from the outset assumed. 
M. Orsat, of Paris, however, has invented an apparatus 
evidently destined to work an important change in this whole 
matter, since it meets al] the requirements of industrial use. 
It is not costly, it is solidly built, and is easily put together ; 
so that any workman of fair intelligence can manipulate it 
quickly, and obtain results even more than sufficient in 
accuracy for commercial purposes. ; 
Prof. Egleston here proceeded to give a detailed descrip- 
tion of the construction and working of the Orsat apparatus, 
accompanied with drawings on the blackboard. He also 
noticed certain possible sources of error in the results ob- 
tained. These, however, are of no account in industrial 
operations; and even in scientific experiments, they are more
