Doctor Stalker :—A few cases came under the observation of 
our station just as I was leaving home, though I am sorry to say 
I did not have time to collect the facts in regard to these cases, 
but my co-worker in the station was sent to a farm seventy-five 
miles from the college where the disease had baffled the local 
veterinarians, which was affecting a herd of cattle. I got a few 
of the facts pertaining to this outbreak ] I think four deaths had 
occurred among calves that were kept together in rather a filthy 
yard. The symptoms as gathered from the owner were all I had. 
I think my co-worker did not see any of them alive, but made a 
post-mortem examination on the last one that died. The symp¬ 
toms very closely resembled the ones in Doctor Winchester s 
paper and some of the pathology shows very close correspond¬ 
ence to that indicated in the paper. The deaths occurred, as I 
recall it now, at an expiration of from four to six days in these 
cases. We have just arranged for a series of inoculations and 
experiments in our laboratory, to work upon the material of 
these animals, none of which is commenced, but we are . in 
hopes of having some facts that will be of value along this line 
after a little, but my knowledge of these cases is very imperfect 
for the reasons stated. . 
Doctor Winchester :—I might state at this time that these 
four cattle that I spoke of in my paper were kept in a place 
where the platform in the stable was about six inches above the 
floor, and until the microscopic report on the case was at hand 
we had to content ourselves with the subject of mystery. But 
after having received that report from Doctor Ernst the subject 
of mystery was laid one side, and the carpenter and mason were 
employed to change things, and since that time no other animals 
have been affected in that dairy. In other words, the barn was 
torn to pieces and cleaned and fumigated. Underneath the fee 
ing box, of course it was not water-tight, and the discharge from 
the animals permeated the floor beneath it, and that was one 
great source of the disease. If there is any possibility of trying 
this material to prevent the disease from affecting the other ani¬ 
mals I think the theory is very acceptable. The second case 
that I read there, the isolated case, was on a farm where the day 
previous to my coming, or day before that, there had been taken 
sick a cow which presented symptoms identical to these others, 
and the owner—or rather, the foreman of the farm, the owner 
was not at home at that time—made up his mind that it was 
the result of eating sheep laurel in the pastures. . The owner, 
with whom I am well acquainted, knowing of the investigations
