THE PRINCIPLES OF BOTANY. 
Hence, I would not advocate a larger dose than five minims, 
if to be repeated three or four times during the day; and I 
must add that I am not satisfied that it would be equally 
beneficial in cases of acute dysentery. One of my hospital 
assistants, at my suggestion, tried it in cholera, and states 
that it checked the vomiting ; but I have no personal expe¬ 
rience on this point. 
Externally, I have tried it extensively on foul ulcerating 
sores, and with benefit; but in one case, when using one 
part of acid to ten of water, to a large sloughing surface, 
symptoms of agitation, with fluttering of the pulse, difficulty 
of breathing, and failure of the heart's action ensued, but 
were combated by lowering the patient's head, giving brandy, 
and inhaling carbonate of ammonia, with cold effusion to 
the head. This proves that even its topical use requires 
care ; and although the whole body might be smeared with 
an ointment of the acid in a case of confluent smallpox (as 
recommended by Dr. Aitchison), yet in a mild case, where 
the absorbent power of a large portion of the skin remains 
unimpaired, such a proceeding would be attended with risk. 
My experience of its use in leprosy is limited, but so far not 
encouraging. Such, briefly, are the results of my experi¬ 
ments, and in making them known I do so, not as proved 
conclusively, but rather to encourage further research, which 
may either confirm or modify them. 
Note by Mr. R. S. Hart, M.R.C.V.S. 
I have given the experiments (by P. Cullen, M.D.) in 
esctenso , and in an ensuing number of the Veterinarian I will 
endeavour to give a memo, of my own experience of carbolic 
acid, the agent having been used by me for a period of four 
years or more. I shall then show that carbolic acid, par¬ 
ticularly Calvert's No. 5 fluid, is an invaluable and economic 
drug, and should in consequence occupy a space in every vete¬ 
rinarian's pharmacy.
