tray or open the slide and allow the admission of air, remov¬ 
ing the vapor if necessary to prolong anesthesia, which can 
be done with care for a surprising length of time. I have ob¬ 
served that during the first few inhalations, the pulse is 
usually much accelerated, but it slows down full and strong 
after. There seems to have been no untoward results from 
not preparing the patient, but I think it is certainly advisable 
to restrict the diet for twelve hours prior to the operation. 
In nervous horses undoubted benefit is derived from the ad¬ 
ministration of an opiate before the operation, either by the 
mouth or hyperdermically. 
I will not tire you with a description of the mechanical 
securing of the animal, and the administration of the drug, 
which has been so ably and fully treated by Dr. Fleming, 
Prof. Axe and others. 
BOVINE TUBERCULOSIS. 
By Dr. E. F. Brush. 
(Resumd of a Paper on the ‘ ‘ Coincident Geographical Distribution of Tubercu¬ 
losis and Dairy Cattle,” read at Albany, at the meeting of the State Medical 
Society, February 5, 1890.) 
The Doctor began by stating that if he could show b} r re¬ 
putable authority that the geographical distribution of human 
tuberculosis coincides with that of the bovine diseases, the in¬ 
ference would be that they stood to each other in the relation 
of cause and effect. In studying the geographical distribu¬ 
tion of pulmonary consumption, the necessity for separating 
imported from indigenous cases in any table of statistics was 
absolute in order to reach any conclusions as to the habits of 
the people and their effects with reference to the disease. 
Many other diseases are conveyed to the human race by 
animals where no doubt exists, but in the case of tuberculosis 
the slow development of the disease is a disturbing factor. 
The danger of animals being infected by man is exceedingly 
small; the danger of man’s being infected by animals is prac¬ 
tically the only danger, and this can be avoided. He thinks 
that the proposition for isolating human consumptives is
