2000 horses, he had not seen an individual case, and amongst 
his private customers, whose horses were fed partly on maize and 
partly on corn, he had not seen a case beyond the two mentioned, 
and those were both foreign, but were not American. He believed 
the disease answered in those animals precisely to the descrip¬ 
tion given by the president. There was not the slightest 
itching on it; and no appearance of skin disease down the 
legs. One of the animals was literally covered ; that was the 
horse that was the first to take the disease. He might add that 
the horses were both of them clipped, and the omnibus horses 
are never clipped in winter time. 
Mr. Broad said he was particularly struck in one case by 
the circular appearance of the wound after the scab had fallen 
off. He examined it, and found a scab under the forepart of 
the saddle. It spread all over the withers and the back. As 
each scab tumbled off there was a perfectly circular depression 
left that yielded to simple local treatment, and did not affect the 
constitution in any way. He had had another case which might be 
of the same nature, or might not. It had been seen by Mr. Mavor. 
This also broke out in numerous small circular patches all over 
the sheath. There was a great quantity of discharge. In that 
case there was no constitutional disturbance till a scab appeared 
high up in the groin, and (possibly from the situation) produced 
intense pain. Poulticing was tried at first, but that aggravated 
it. At Mr. Mavor’s suggestion they tried some sulphate of 
calcium, and a simple local wash, under which treatment it soon 
recovered. In his opinion it was another form of the same 
disease. 
Mr. Shaw said he had seen many of these cases, and those 
he had seen had been principally among the tram horses, 
and they were nearly all American horses. There were several 
cases to be seen now at Cambridge Heath. The scab had 
been almost like a ringworm, and one of the horses that had 
been turned out at grass up at Clapton was almost hairless 
when fetched up. 
Professor Axe said it appeared to him that two very important 
questions were suggested by the observations made. These were, 
first—was it a contagious disease, and, if so, secondly, was it of a 
parasitic nature ? He might say that he had taken some pains to 
determine the latter question. He knew too well the difficulties 
attending on the detection of parasites to make any definite re¬ 
marks in reference to that question. It was one that should not 
be hastily disposed of at any time, inasmuch as, in accordance with 
the suggestion of Mr. Hamilton, very considerable difficulty 
attaches to the finding of parasites, even of such parasites as the 
acarus, a comparatively large one, as compared with some forms of
