172 OBSERVATIONS ON A FEW CASES OF FORRIGO. 
esting outbreak of P.favosa amongst young cats. The farmer 
informed me that he had lost five young kittens, all diseased, 
within seven weeks, and that there were two still remaining, 
also diseased, which I should see. None of the kittens had 
been bred on the farm, but had been got at different times 
from other farms in the locality, and had been destroyed or 
died at various times as they became apparently hopelessly 
diseased. Every fresh kitten or kittens, however, as surely 
as they arrived invariably became affected; and the re¬ 
maining two, the sixth and seventh, were labouring under 
precisely the same disease. What could it be ? 
On examining the two kittens, which were comfortably 
ensconced on the parlour hearth-rug, I discovered to my 
surprise that they were evidently both the subjects of P. 
favosa. There were the peculiarly shaped favi and favous 
crusts, on the head and feet chiefly, of both kittens. The 
feet or paws were slightly swollen and somewhat painful, as 
I thought from the gingerly way in which they walked 
about. 
Whether the first pair of kittens brought the disease with 
them, or got it after they came, will never be known; certain 
it is, however, that they left the vitally contagious germs 
behind them, which became the means of infecting their five 
successors. 
As the farmer had two young children daily playing and 
tumbling about in the parlour, I advised him to destroy the 
two remaining kittens for fear of infection, even although, as 
he said, the children were not allowed on any account to 
touch the kittens. I regretted much afterwards that I did not 
take the kittens with me for experiment, but one loses many 
a good chance in this way for want of forethought. 
I shall draw my remarks to a close by mentioning that 
the cattleman, already spoken of as having had P. favosa on 
his upper lip in the spring of 1869, was again attacked with 
same disease in December last. The disease manifested 
itself this time on his right arm, about midway between the 
wrist and elbow, two irregularly circular spots about the size 
of a sixpenny piece each. 
I had an opportunity of examining the diseased spots in 
this case before the usual favous crusts had formed, and 
found them considerably raised above the level of the sur¬ 
rounding epidermis, highly inflamed and irritable. One spot 
had three and the other four bright yellow flattish pustular- 
looking points, which were evidently the veritable/am of Tinea 
favosa. The contagium in this case had again been received 
while dressing young cattle affected with ringworm, i. e. P, 
scutulata.
