year; this was not the case, however, in Langemyregaard. 
The explanation is that there the cows had aborted in an 
early state of pregnancy—before the fifth month—, and that 
many others had not conceived in proper time in spite of 
previous normal birth. In the time between December 1, 
1907 and September 1, 1908 only three abortions were re- 
ported on the four estates; they were all in older cows, while 
generally abortions take place in young cows or heifers. 
In conclusion I would like to say that we are able to com- 
bat the damage from infectious abortion to a considerable 
extent; even if we cannot prevent the spread of the infec- 
tion and the abortions, we can bring the consequent lesions, 
such as metritis, and sterility, to a speedy conclusion. Thus 
we prevent a decrease in the milk-production, and, in most 
c2ses, a second abortion.
