normal size, hard, of a grayish white color, and had the ap¬ 
pearance of a mass of tallow ; its cavities were much reduced 
in size, the valves were thickened, endocardium thickened, 
grayish white. 1 shall never forget my stupefaction when I 
looked into that chest. Oh ! but where were the lungs of that an¬ 
imal? The fact was that there were no lungs to be seen at 
first. The chest being opened, showed a mass of liquid, which, 
evacuated, showed the heart and pericardium in the state 
above described, but no lungs could be seen for the following 
reason : Inflammation had invaded the whole pleura, which 
presented the same appearance as the pericardium ; it was 
thickened as the latter, and was completely adherent to the 
sides and diaphragm, so that the lungs were imprisoned in 
it and firmly stuck to the ribs; it was only after having dissected 
the pleura from the sides that they could be seen, compressed 
and congested. No trace of foreign body could be found, 
though the researches were long and carefully made. 
This case is remarkable for the length of time it lasted 
(17 days), and is interesting inasmuch as it shows the resem¬ 
blance at its outset with gastritis and pulmonary, or, rather, 
respiratory organs. It may tend to caution practitioners to 
be exceedingly careful in their examination of patients sup¬ 
posed to be suffering with these diseases. 
THE USE OF AN/ESTHETICS IN VETERINARY PRACTICE.

A Paper read before the Ohio Veterinary Medical Association at Columbus. 
It is not my desire to-day to tire you with an exhaustive 
paper dealing with anaesthetics from a theoretical standpoint. 
The history of the discovery of the different agents that 
are used to produce anaesthesia, the modes of preparing them, 
etc., can be studied, if we wish to do so, from our text-books, 
and, in my opinion, it is not in good taste to read lengthy 
theoretical articles at our meetings, for, at the best, they can 
only be a repetition of what we all have an opportunity of 
reading at home. To be sure, if we should discover some¬ 
thing of importance pertaining to our profession, we should,
