298 DR. CHAMBERS, ON MUCUS AND PUS. 
differ from those of Rindfleisch in this particular. Buhl 
contends that the epithelial cells increase by simple division. 
Rindfleisch asserts that he has watched a process going on 
analogous to that of yelk division. It appears that both 
may be right. 
In his third lecture, Dr. Chambers treats of the chemical 
nature of pus compared with that of mucus, and enters into 
some details as to the production of pus under inflammation, 
and the various external agents which may affect the mucous 
membrane. He also makes some very able remarks upon 
the manner in which various drugs act beneficially im certain 
diseases through the mucous membrane. Some of Dr. 
Chambers’ speculations are certainly wild, and he frequently 
clokes a very simple and obvious fact under a multitude of 
words; nor have the lectures the merit of much originality, 
being more a summary of what has been done on the sub- 
ject than anything else: but, on the whole, they are well 
worth the attention of physiologists and pathologists, and 
will prove a useful addition to the English literature of the 
subject.
