In Table III the record of milk from another cow is given. Here 
again we have positive agglutination coupled with abortions and milk 
shown to contain Bad . abortus by guinea-pig inoculation. 
Table III .—History of milk from a cow with a record of frequent abortions 
[Agglutination reaction at middle of milking, when various quantities of milk were added to test tubes 
containing bacterial suspension] 
a Guinea pigs inoculated intra-abdominally with milk from each quarter had typical Bad. abortus 
lesions when autopsies were performed 10 weeks later. 
* Aborted a 7-month fetus. 
c Right rear quarter, positive guinea-pig inoculation. Right front quarter lost, and left rear and left 
front quarters negative, 
d Aborted a 7-month fetus. 
In Table IV is given the record of milk from a cow that has never 
aborted. On June 16, 1915, agglutinins had appeared in all but the 
left front quarter. Guinea-pig inoculations made on June 30 were 
positive for infectious abortion in all but the left front quarter. On 
October 16, 1915, the reaction had spread to the left front quarter. 
Milk from this quarter is now being tested by guinea-pig inoculation.

a Guinea pigs inoculated intra-abdominally with milk from each quarter had typical Bad. abortus 
lesions and blood reactions, with exception of left front quarter, which was normal.
