Clinical Notes on Dumas Short-Horns. 



The two Shorthorn calves, owned by Dumas, of Ar- 

 lington, Ala., were inoculated only once, (see Table V). 

 This was done in November. The following August Mr. 

 Joel Dumas writes me stating that about ten days after 

 the calves w^ere inoculated the primary inoculation fever 

 appeared and continued about two weeks, the tempera- 

 ture ranging from 103 to 106. The heifer's temperature 

 was invariably higher than that of the bull calf. Dur- 

 ing the high fever the bowels were kept active by drench- 

 ing the calves with raw linseed oil, and w^hen they would 

 not eat they were drenched with milk. After recovery 

 they were turned into a pasture with other cattle, and 

 "have had ticks on them all along.'' He says: "My 

 Shorthorn calves have done very well, and I think now 

 they are perfectly immune." Nov. 1., these calves were 

 safe. 



Notes on the last nine cases in Table No. V : 



F. G. Matthews, of Florence, Ala., inoculated these 

 animals, and under date of April 8, 1901, w^rites me as 

 follows : 



"I first measured the dose in a small tAvo drachm 

 graduated, allowing something over a half drachm for 

 a dose (2 cc). Nine head of cattle were inoculated. 

 Seven of them were Jerseys ( one 6 months old, one 18 

 months old, four were 2 years old, and one was 4 years 

 old) ; they came from Kentucky; the other two were 2 

 year old Herefords, and came from the St. Louis mar- 

 ket. All of these cattle were brought to Alabama dur- 

 ing the past winter. 



"The vessels used were sterilized by placing them in 

 cold water and bringing it up to boiling. 



"On the 13th of March I drew the blood from a native 

 scrub bull, 18 months old, defibrinated it, and imme- 

 diately inoculated the Herefords.
