A. D. KNOWLES. 
The only one that Mr. Arnold has lost, while showing the 
symptoms, was a steer about a year and one-half old, which had 
fallen into a ditch on the night of the 3d of January, 1901, 
everything indicated that the animal chilled to death while 
lying on his back in the ditch. 
I held an autopsy about thirty-six hours after death and 
found the following conditions present: 
The body showed no signs of decomposition and there was 
no tympanites; the post-mortem was held by the field operation, 
exposing all of the internal viscera as a whole, after which the 
contents of the intestines, stomach and bladder were exposed; 
then we examined carefully the external and internal condi¬ 
tions of the heart, lungs, liver, kidneys and spleen. 
There was nothing to indicate disease or abnormality until 
the cranial cavity was reached. 
Upon opening that cavity the dura mater and arachnoid 
showed nothing characteristic, but there seemed to be much 
more than the normal quantity of the subarachnoid fluid and 
the vessels of the pia mater were greatly distended with blood ; 
there was nothing else to attract especial attention. 
There were a greater number of cattle affected on Mr. Ar¬ 
nold’s farm last year than there has been any previous year. 
Mr. Arnold^lias had sheep, which he says have shown the 
same symptoms, and he thinks some have died from the affec¬ 
tion. 
The farm referred to lies in the north part of Vernon 
County, Mo., and is composed of about eight hundred acres of 
black limestone soil; it is all set to timothy, clover and English 
blue grass. 
The farm is exceptionally clear of weeds and brush, except 
forty acres, of which I shall speak later ; there is a creek running 
through the farm from south to north, but the cattle receive 
water mostly from tanks fed by large ponds, and the f water sup¬ 
ply in the tanks is regulated by floating valves; the ponds are 
all fenced so that no stock can get to them. The pasture was 
excellent, and the cattle did not receive any grain or hay until
