two daily at the commencement and one daily afterwards. 
Tonic treatment similar to that of case I was continued until 
December 29th, at which date the animal had made a good 
recovery. 
Cases III and IV differed only from the preceding in 
their severity, their treatment being essentially similar. The 
latter received 5 injections, the former 15. The apparent 
anomaly in regard to the number of injections required by 
case III is explained by the fact that this animal was prim¬ 
arily stabled upon a quay, near which was a large sewer outlet, 
and where always at low tide was an acre or so of stinking 
mud. The owner was at first greatly disinclined to have his 
horse removed, but after two relapses readily consented. 
The whole of these animals are now at work. It is per¬ 
haps worthy of remark that only case IV had received any 
treatment for influenza, the others had been allowed by their 
owners to take their chance until the purpura was noticed. 
The solution used throughout was of the strength recom¬ 
mended in Mr. Dollar’s article, viz., iodine one part, iodide of 
potassium five parts, water 100 parts. When carefully and 
slowly injected there is rarely any cough, and during the 
operation the patient frequently seems to be soothed almost 
into sleepiness. 
I have endeavored only to give a bare outline of the treat¬ 
ment pursued, but it should be mentioned that careful nursing 
always played a prominent part in it. Milk and eggs were 
given very freely, and at the commencement supplied the 
staple subsistence. Warm supporting bandages were always 
put on the limbs and carried as high up as possible. 
I gather from the experience gained in these cases that 
three or four large doses of iodine solution injected consecu¬ 
tively are more permanent in their effect, and hence more 
likely to prevent the relapses which are so frequent in this 
affection, than are five or six equally large doses given inter¬ 
mittently with small ones, or with any other medicine admin¬ 
istered in the usual way. 
A notable feature, too, is that fairly large doses of iodine, 
given either as pure iodine in a ball, or in any of the liquid '
