750 LIVERPOOL VETERINARY MEDICAL ASSOCIATION. 
Mr. Reynolds expressed his regret that, owing to some other public 
meetings, Professor Walley had not a better audience to listen to his very- 
excellent paper. In regard to the intra-venous injection of ammonia, he 
should like Professor Walley to enlighten them a little more in detail as 
to the dose, the strength of the solution, and the general mode of pro¬ 
cedure ; and also if he thought that, in cases of blood poisoning from 
wounds in the feet of horses, that the intra-venous injection of ammonia 
would be beneficial. 
Mr. Greaves said that he did not think that in these foot cases death 
was caused by absorption of matter or blood poisoning, but that it was 
due to chronic disease of the lungs or other internal organs, which 
existed concurrently with the injuries to the feet. In regard to the 
beneficial effects of bleeding, he related the history of a case of chest 
influenza in a horse. This animal had been ill for five days, had eaten 
nothing for three days. Pulse 96. The late Mr. John Lawson saw the 
case with him. I recommended bleeding; he strongly objected to it. The 
horse made no improvement, however, and on the following day I bled 
him, taking six quarts from him. When I told Mr. Lawson what I had 
done he said your patient is almost certain now to die. I saw the horse 
six hours later, and he looked livelier, and in another six hours his pulse 
was down to 86, after which he gradually improved, and finally recovered. 
Phlebotomy relieved the congestion that existed, and gave nature 
a chance. But while he (Mr. Greaves) admitted that a great 
change had taken place in our mode of treating diseases, he was also of 
opinion that the character of the diseases themselves had changed. 
After some remarks from the Secretary , who expressed the hope that 
Professor Walley would publish his paper, the Fresident called on the 
Professor to reply. 
Professor Walley , in reply, said that he was obliged to the President 
for giving him the opportunity of coming to read a paper, and to the 
members for the appreciative reception which they had given to it. He 
then referred to the various criticisms and questions of the members. 
As to the best mode of administering ammonia or its carbonate, he 
(Professor Walley) preferred giving it in solution, when it can be done 
conveniently; but you require to dilute it so largely that it becomes 
difficult to administer in some cases. As to the reason why you cannot 
administer ammonia and aconite together in solution, it is because the 
action of aconite becomes thereby increased to such a degree that sym¬ 
ptoms of poisoning manifest themselves almost before you get the medi¬ 
cine down. Potass and aconite in solution had the same effect; these 
agents in solution seem to favour the absorption of the aconite. As to 
animals dying with their arteries full of black blood after the continued 
use of ammonia, referred to by Mr. Greaves, he (Professor Walley) said 
that the continued use of ammonia would produce fluidity of the blood, 
and in large doses solution of the hsemato-globulin, and thus prevent the 
oxidation of the blood ; but he was strongly of opinion that the character 
of the blood in these cases was due to the disease more than to the 
administration of ammonia. In regard to the benefit of external stimu¬ 
lation, referred to by Mr. Morgan, people get disgusted by seeing 
stimulation overdone; some practitioners persisting in applying irritants 
during the whole course of the disease. But in the early stages, or at a 
turning point of the disease, external stimulation is of decided benefit. 
You thereby stimulate the nerve centres. 
The professor here related the history of several cases, where marked 
benefit was derived from abstracting blood, and following up that by 
internal and external stimulation. As to the apparent contradiction
