directions for the food to be immediately changed. This was 
done, and the animals placed on bran mashes, turnips and 
carrots. On the recommendation of Professor Simonds I 
also gave them the hyposulphite of soda in two-ounce doses 
daily. Notwithstanding these precautionary measures three 
more of the cows died during the following week. I now 
managed to get them removed from the place, and since then 
there has not been a fresh case. 
I may add to this short account a very important fact, 
viz., that during the 'post-mortem examination, one of the 
men accidentally cut himself, and has since been dangerously 
ill, doubtless depending on this cause. A cat, also, which 
partook of some of the flesh of one of the diseased animals, 
died suddenly very shortly afterwards. 
I am aware that this unexpected occurrence of splenic 
apoplexy does not essentially differ from many others, but it 
is the first, so far as I know, which has taken place in this 
part of Lancashire, and hence the greater reason why i't 
should be recorded. Besides this, we can only hope to ob¬ 
tain a better knowledge of the causes of this remarkable 
blood affection by detailing the circumstances under which 
each particular outbreak shows itself. In this case too rich 
a diet, or, in other words, too great an amount of hydro- 
carbonaceous and albumenized matters having been supplied 
to the animals, would appear to be the chief cause of their 
succumbing to splenic apoplexy. 
OBSERVATIONS ON A FEW CASES OE PORRIGO. 
By Alex. E. Macgillivray, Veterinary Surgeon, Banff. 
Porrigo, otherwise Tinea , I have met with among the 
lower animals in various forms, such as P. scutulata , P. 
decalvans, and P. favosa. The first of these is very common 
amongst cattle, horses, &c.; the second, not so common, I 
have seen in cattle, horses, dogs, and hares, and the third, 
the least common of all, I have found in cattle and cats. 
P. scutulata and P. favosa are extremely contagious and 
easily communicable, both from animal to animal and from 
animal to man. Instances of the transmission of P. scutulata 
from the lower animals, chiefly cattle, to their attendants 
occur every year, generally in spring and autumn. 
More remarkable still, however, is the fact that the con¬ 
tagious materiel from P. scutulata in the lower animals will 
produce clearly defined P. favosa in the human subject. I
