those in Wilhelmsborg. The stables, however, were not so 
well built, and the floor was contaminated from several cases 
of infectious abortion. Malignant metritis cases after parturi- 
tion were frequent, especially after retentio secundinarum, 
the operative removal of which would cause death. Steril- 
ity of course, was frequent through a number of years. The 
septic as well as the more chronic catarrhal metritis cases 
were cured in a remarkably short time, especially after the 
treatment of the retained placenta was changed. The per- 
centage of pregnant animals became satisfactory, and it was 
evident that this fact was in correspondence with the elimin- 
ation of the septic and purulent metritis. 
On most of the other big estates irregularities of concep- 
tion were more or less variable, but always too considerable. 
On the small farms these troubles very rarely continue 
through several years, yielding to the treatment and very 
often disappearing completely. 
Interesting examples are the stables in Lille Myregaard 
and in Gadegaard Nylars. At the first place the trouble be- 
gan in 1905 without any apparent cause, and spread over the 
whole herd. Twenty-one cows out of thirty were 
treated; eighteen had inflammatory processes in the uterus 
and in the cervix, three were apparently normal and nine 
had cysts in the ovaries. Starting in the fall of 1905 the 
yellow bodies in each individual case were pressed out, with 
very little success, as only three cows became pregnant. 
The rest had to be treated with irrigations before conception 
could take place. Of the twenty-one cows sixteen then 
became pregnant, and since then the conditions are nearly 
normal, with only sporadic cases of sterility. 
In Gadegaard Hylars the trouble began in the beginning 
of the year 1906; all the cows which had calved and had 
been in heat again before Christmas 1905, became pregnant 
without any difficulty, but all the cows which calved after 
Christmas had to be treated several times with great care 
before they conceived, again. The whole herd had to be
