Q. ARCHIE STOCKWELL. 
the lungs or hydatids of the liver, or both, and tubercular de¬ 
posits throughout the body, formed both with serum and with 
pus. 
The first endeavor to check the disorder was to separate the 
well from the sick, placing the former in non-infected barns. 
But whether the man who had them in charge conveyed the in¬ 
fection from one barn to another in his clothing, or carelessly 
employed the utensils set apart for the infected sheep in which to 
feed the sound ones, is not known. It was supposed a stop had 
been put to the ravages of the disease when the sound sheep had 
been isolated from those infected for more than fifteen days with¬ 
out indications of disease; but all at once four new cases were 
perceived, three of which terminated fatally on the fifth and ninth 
days. During this time two ewes had the distinct form of variola 
so mildly as to pass unperceived had not accident dra^/n attention 
thereto. These were removed from the others, as it was thought, 
before they had opportunity to communicate the malady, for it 
was expected all attacked would die, being near the time of 
lambing. 
At this point virus taken from the pustules of infected sheep 
was employed to inoculate the sound ones, though with little hope 
of favorable result; some had lambed just before inoculation,the 
remainder soon after. The lambs, too (twelve in number), as fast 
as they appeared, were inoculated on the third or fourth day. 
All, lambs and adults, took the disease mildly, and recovered 
readily, with no untoward results, and subsequently proved the 
healthiest of sheep, though nothing more was done for them than 
to provide suitable diet and an abundance of pure, fresh air. 
Save in a single instance, the disease, as the result of inoculation, 
manifested itself only for two or three days, after which they ate 
and ruminated naturally and freely. Some would never have 
been suspected of variola but for the inoculatory incisions, that 
contained good, viable pus, or from the discovery of the few 
pustules that appeared here and there, isolatedly, after a few 
days. 
The exception above noted, the one longest and most affected, 
exhibited indirect inflammation at the point of inoculation, with a
