that any considerable numbers of ticks were carried. There did 
not seem to be any constitutional disturbance due to their pres¬ 
ence, as shown either by the thermometer or by hseinatokrit 
examinations of the blood. The experiment closed August 
31st, 1899. There was no fever among the cattle, nor had there 
been any. The average per cent, of red blood corpuscles was 
33.4 at that time. 
KRUGER.—6 HEAD OF REGISTERED HEREFORDS. 
This lot consisted of six pure bred Herefords, two bulls and 
four heifers, whose ages ranged from six to twelve months. 
They were raised near Emporia, Kansas, and had been shipped 
south, where they arrived December 7, 1898, at the Carter 
ranch in Bee county, Texas. 
On December 17, 1898, each received 1 cc. of defibrinated 
blood from the jugular vein of a three-year-old cow on the 
ranch. This cow had a considerable number of ticks on her at 
this time. The calves were kept in a dry lot and fed bran and 
cactus, and watered from a cistern. 
January 23, 1899. Saw these calves. All have lost flesh, 
and there is marked looseness of their bowels. They were 
evidently in the secondary fever period. The temperatures were : 
Bull No. 1, 106 degrees; Bull No. 2, 105 degrees; Heifer No. 
366, 105.8 degrees ; Heifer No. 51, 107 degrees ; Heifer No. 
525, 106.5 degrees ; Heifer No. 57, 104.2 degrees. February 
6, 1899. Temperature has fallen to the following: Bull No. 1, 
104 degrees ; Bull No. 2, 104 degrees ; Heifer No. 366, 103.5 
degrees; Heifer No. 51, 103 degrees; Heifer No. 52, 102.5 
degrees ; Heifer No. 57, 104 degrees. June 27, 1899. Saw 
these cattle. Heifer 366 is evidently pregnant. The cattle 
appear in good condition. 
September 15. Bull No. 1, in good thriving condition. 
Bnll No. 2 ; inoculation has caused arrest in development in 
this calf. He has been thin but is doing well now. The 
heifers have done well ; the oldest one dropped a calf recently. 
No deaths.
