Table 1 shows a total of 2,806 cases where nodules or granules in 
the vulvar mucosa were macroscopically visible, as against 444 cases 
where they were not visible. This makes the average visible infec- 
tion in all classes of animals 86 per cent. 
Viewing the malady as one fundamentally venereal in character, 
though readily and abundantly transmitted otherwise, we observe 
the lowest ratio of infection, 61 per cent, in heifer calves slaughtered 
for veal and ranging between 6 weeks and 1 year in age, presum- 
ably because they had not copulated and hence had escaped the 
basic mode of infection. The next lowest ratio of infection, 68 per 
cent, is that of spayed heifers, where again, when spaying had been 
properly done, copulation was excluded as a factor in transmission. 
In the next class, comprising entire females from 1 to 4 years of 
age, essentially all of which had presumably been bred, the number 
of affected advances to 95 per cent, to fall again to 85 per cent in cows 
over 4 years of age.
