acid in tlie treatment of these cases, as he had tried it repeatedly, 
and found that invariably it produced deep-seated inflammation 
and retarded the healing process. 
Mr. Robinson was of opinion that the disease is carbuncular in 
its aspect. He corroborated the statements of Mr. McLean with 
regard to the obstinate nature of the disease. He upheld, how¬ 
ever, the carbolic acid system of treatment, and said that he used 
digestives freely along with the carbolic acid, which he thought 
essential in order to bring about healthy granulations. He also 
approved of cantharides ointment, having used it occasionally in 
aggravated cases. 
Mr. William Anderson was of opinion that the disease was 
caused by irritating matters, conjoined with application of cold 
and wet to parts naturally sensitive. Pie ascribed its more 
than ordinary prevalence to chemical refuse in the streets, which 
cannot be altogether avoided in our busy thoroughfares. 
He thought that where tramway operations are going on the 
chances are greater of contracting the disease. Had known in¬ 
stances of horses in which the unhealthy sloughs had taken place 
very rapidly where they had been daily worked on streets where 
the tramways w T ere being laid. The man in charge had fre¬ 
quently attributed the disease to the materials used in laying the 
tramway. 
Mr. McLean remarked that he had noticed the disease to be 
more common among the omnibus horses which go to and from 
the Botanic Gardens, where the line of tramway was being 
laid. 
Mr. Lottie said he could not see how that could cause the dis¬ 
ease, as it exists in places where there are no tramway operations 
going on. 
He also spoke at some length on the nature of the disease; 
and his theory being that there was a stoppage of the circulation 
at and around the affected part, which accounts for its obstinacy 
to heal. Gangrene and death of the part take place, and as a 
result there would necessarily be sloughing of the skin. His 
treatment consisted of poulticing until he had removed the inflam¬ 
mation, and afterwards the application of cantharides ointment. 
After sloughing had taken place he used alum and acetate of 
lead in equal parts, made into a paste with water. He had tried 
various means besides these, and had sometimes found that after 
the healing of the sore sloughing would again take place, and 
ulceration recur. He had observed deep cicatrices and indura¬ 
tions as a final result. 
Mr. Lollock said that he had seen a good many cases in pit 
horses and carriage horses, as well as heavy horses. 
Mr. Robinson remarked that oedema of legs was often associated 
with file ulceration.
