The reprehensible practice of muzzling dogs in hot weather 
ought to be prevented by law. No animal suffers more intensely 
from thirst than the dog, and it is gross ignorance on the part 
of the laity who practice it and it is cruelty to the animal, and 
serves no good end whatever. 
Pathological Anatomy . — Post-mortem examinations have 
thrown much new light upon this malady, and much special 
' attention has been given by certain eminent pathologists to this 
work. The chief morbid changes which are described are evi¬ 
dences of congestion and inflammatory action in certain portions 
of the brain and spinal cord, and most particularly in the locality 
known as the “ respiratory centre ” of the medulla-oblongata, 
where the accumulation of ‘Tencocytes” around the small blood¬ 
vessels and in the surrounding nervous substances are a promi¬ 
nent phenomenon, similar changes are also found in the salivary 
glands. 
On the whole, however, it can scarcely be said that the for¬ 
midable array of symptoms above narrated are accounted for by 
these appearances, which in the opinion of some, are in all like¬ 
lihood merely the results of antecedent processes of an occult 
nature, affecting the nerve centres, and forming the essence of 
this disease. The eighth pair of nerves, which are largely con¬ 
cerned in the processes of respiration and deglutition, are con¬ 
gested in a marked degree, and it is upon this portion of the 
nervous system that the poison or ptomaines most? powerfully 
exerts its specific action. But that the whole great nerve cen¬ 
tres, viz., the brain and spinal cord, as a whole, are profoundly 
affected, is manifest in the tendency to general convulsion, the 
remarkable hyperaesthesia, and the mental perturberation of the 
victim. 
I could write more than I have already written on the latest 
experiments on rabies, and remarks on post-mortems by many 
able men, also much on treatment by our recent bacteriologists 
such as Sternberg, Gmelin, Lehman, Marchand, and others, but 
of this you can read at your leisure. I will, however, quote one 
master mind, at the risk of him quoting Pasteur.
