A study of this table shows that of 14 mothers, 7. or 50 per cent, 
transmitted an immunity to their young sufficient to withstand the 
effects of an LA dose; all living except Nos. 1424A, 1424B, and 
1524B. which lived 3, 2, and 4 days, respectively, longer than their 
controls. Of a total number of 24 young pigs shown in this table, 13, 
or 54.16 per cent, were resistant to an LA dose. 
Of the mothers that received the toxine-antitoxin mixture, 7, or 70 
per cent, transmitted an immunity to their young. 
The fact that no mother which received a dose of toxine alone trans- 
mitted an immunity to her young is very plainly shown.

An examination of this table shows that of 12 mothers 6, or 50 per 
cent, transmitted an immunity to their young. 
Of a total number of 21 young pigs treated 11, or 52 per cent, were 
resistant to a Altai dose for control pigs. 
Of the mothers that received the toxine-antitoxin mixture 75 per 
cent transmitted an immunity to their young.
