AZOTURIA. 
237 
Summed all up, we may conclude that the faults of chloro¬ 
form are: 
1. Danger of death from heart paralysis, most frequent, 
perhaps, in man. 
2. From respiratory paralysis, more frequent in animals, 
and almost invariable in those that are feral, with two or three 
exceptions. 
3. From paralysis of the vaso-motor centre, comparatively 
infrequent at all times, but probably less so in man than ani¬ 
mals. 
4. Chloroform requires a carefully graduated admixture of 
atmospheric air during administration, more than three and 
one-half per cent, being dangerous, and four per cent, fatal, to 
man. Most feral animals demand less air than man to attain 
a satisfactory result. 
5. Despite the contrary assertion ol the Hyderabad Chlo¬ 
roform Commission, dogs—tfie domestic variety especially— 
are more resistant to the vapor of chloroform than human 
beings; feral canines of different breeds exhibit varying resis¬ 
tance, usually less than domestic dogs that are not surfeited. 
6. Cats are less resistant than dogs, and anaesthesia is fatal 
in nintey-five per cent, of the Angora breed. Among the Le- 
poridce fifty per cent, of the cases of anaesthesia are fatal, and 
usually from shock inducing heart rupture. Ovines also, 
usually, bear chloroform but illy. 
7. Horses, as a rule, if not subjects of amyloid disease, 
melanosis, or not too obese, usually bear chloroform well. I 
have, however, had no opportunity to, witness the fatal action 
of this agent on equines. 
AZOTURIA.

A Paper read before the Massachusetts Veterinary Medical Association. 
Gentlemen: I am inclined to think that azoturia as it ap¬ 
pears in the stables of a horse railway company will, as a 
subject, not be uninteresting to you, because it has seemed to 
me that there are in one way and another certain facts which
