18 ELEVENTH ANNUAL REPORT OF THE 
spring and fall, a few cases appearing at each test. Most of 
those reacting during last fall, were of animals that had pre- 
viously reacted and had been isolated. ‘There has been one 
outbreak of hog cholera, which was promptly checked by isola- 
tion, disinfection and the use of our contagious ward stalls in 
the veterinary hospital. Infectious abortion has also con- 
tinued to a rather limited extent in the dairy herd. It seems 
very difficult to get rid of this infection when once it has 
obtained foothold. Two cases of lumpy jaw appeared in our 
herd during the past year, but no serious trouble is anticipated. 
About 200 lantern slides have been prepared for class 
demonstration work, and the museum has been developed, 
until it has become quite an important teaching feature. 
Publications —Dr. Reynolds has published a text book, “Vet- 
erinary Studies,” for use in the veterinary classes of the farm 
school, and the short course work. This book has been very 
well received by agricultural colleges and agricultural college 
students, twenty-two agricultural colleges having already 
adopted it as a text book, or signified their intention of doing 
SO. 
sulletin No. 82, on Hemorrhagic Septicemia, containing 
about 30 pages, was published from this department, and was 
very favorably received by the agricultural public, by the 
veterinary profession, and the agricultural papers. The in- 
vestigations and other work reported in this bulletin deal with 
the practical features of this serious disease. ‘This bulletin dis- 
cusses the practical bearing of the disease upon the live stock 
interests of Minnesota, and shows that it is a very serious 
problem. The peculiar feature in connection with the cause 
of the disease, is that the rod-shaped germ which is now rec- 
ognized as the specific cause is apparently identical with the 
swine plague bacillus, and very similar to the chicken cholera 
germ. ‘The history and development of cases are given at con- 
siderable length from actual field observations. The veterin- 
arian had opportunity to study quite a number of cases 
throughout their entire course, and has put these data on 
record in Bulletin No. 8&2. 
Attention is drawn especially to the fact, that ante-mortem 
symptoms are as a rule unsatisfactory, the acute cases dying
