calves became sick at the usual time after inoculation (about io 
days), and about one-half of them were severely affected. 
Three of the number died. At this time the manager noticed 
that many of them had some ticks on them. By April 24th six 
had died, and the entire lot showed sickness. About June 1st 
they were turned into a large pasture of thirty thousand acres, 
among the range cattle, and have remained there the whole 
summer. The owner says they are doing very nicely (August 
15, 1899), an d up to this time seven had died of fever. Six 
have died of blackleg, and one from accident. He says that in 
his opinion they should have been kept up in a dry lot until the 
inoculation fever was over before exposing them to the ticks. 
BURGESS.—68 HEAD OF REGISTERED SHORTHORNS. 
This lot consisted of 68 head pure bred Shorthorns, whose 
ages ranged from 8 to 12 months. They were raised in Ken¬ 
tucky, and arrived at the Blue Mound Ranch, in Wise county, 
Texas, November 24, 1898. On January 4, 1899, each one re¬ 
ceived subcutaneously 1 cc. of defibrinated blood from a two- 
year-old steer that had been raised on the ranch. The owner of 
these cattle reports, under date of March 4, 1899, that four of 
the calves have died and that the remainder have been reduced 
in flesh, but appear healthy otherwise. About June fever ap¬ 
peared among them and about one-half of them showed severe 
symptoms ; by July 24th twelve had died in all.

OPHTHALMIA.* 
By G. Ed. Leech, V. S., Milwaukee, Wisconsin. 
When the subject of periodic ophthalmia came up at the 
last meeting, I little thought that I would be called upon to 
write a paper upon the subject, and when the Secretary wrote 
me in regard to it I did not have any great desire to fake it up, 
for it is with some such feeling of dissatisfaction as must fill
