Lyperosia. Further examination of these apparently healthy 
animals weeded out five more cases in August. The balance, fourteen, 
continued healthy, and of these thirteen were taken for transport 
work in September. Tiiey did the work well, and showed no greater 
death-rate on the 400-mile march than did the other ninety cattle 
taken. 
After the first examination, at which only suspected cattle were 
presented, all animals inspected were, without exception, free of any 
clinical signs of the disease. These became manifest m about two 
weeks time, and death took place within an average of thirty days ol 
diagnosis. This is the average between these dates in fourteen 
apparently healthy cattle, and excludes all those upon which expen- 
mental work on treatment could he held as influencing the course 
the disease in either direction. 
With a disease of such rapidity and virulence, we consider i 
highly improbable for the infection to have lain dormant in th 
animals since August, iqoG. From an examination of all condiliom
