ord about one hundred cases of this kind, among them 
pregnancies up to three and a half months. A very remark- 
able case I had in Skrébelevgaard, where I made a rectal ex- 
amination in a cow and found a pregnancy of three and a 
half months. However, I was informed that the cow had 
not been bred, and then corrected my diagnosis, supposing 
the presence of a pyometra. The cervix was open, and I in- 
fused a Lugol solution of 1:3:97 strength. The cow, 
however, was pregnant, yet did not react with an abortion. 
The Results of the Treatment. 
Several facts are to be considered in estimating the re- 
sults of the treatment as they depend: 1, on the care and 
efficiency, with which the breeding of the herd in question is 
done, 2, on the percentage and character of the prevailing 
irregularities and 3, on the technique and frequency of the 
treatment. ; 
As to the first point, it is of course necessary that the 
animals be bred at the right time and to a good bull. Both 
points are very often neglected; the estrum symptoms of the 
cows are not sufficiently noted and are often passed by, or 
the mating act is not satisfactory on account of a mediocre 
or abused bull. The estrum symptoms in some cows may be 
so slight or of such short duration that even a good-observer 
may overlook them. In nearly all the large herds I find 
cases of this kind, and there the care is generally better than 
on the smaller estates. It is, therefore, advisable to make 
regularly rectal examinations at least on the large estates, so 
as to control efficiently the breeding of the animals. 
The second point is of more importance still; it concerns 
all the animals of a herd, while the overlooking of the estrum 
is more or less exceptional, the circumstances that breeding 
results are some times better in small stables than on large 
estates, is often explained by the better attention which is 
paid there to the mating act. In the large herds the breed- 
ing makes much work, and is very often ordered to be done 
in the leisure time of the attendants, much to their displeas-
