It was pointed out by them that when southern cattle were freed from ticks they would not when kept together in small enclosures transfer the disease to susceptible ani- mals, but that when susceptible cattle became infested with the ticks.

The infection of northern cattle with Texas fever by southern *This tick was first described by C. V. Riley in 1868 as Ixodes bovis. Later, Cooper Curtice investigated this parasite (Biology of the Cattle Tick, Journ. Comp. Med. and Veterinary Archives, July, 1891, Jan., 1892) and gave it the generic name of Boophilus (ox loving). This seems to be the only genus of cattle ticks which transmits the para- site of Texas fever. Recently Karsch's genus Margaropus has been proposed as the correct name instead of Boophilus. fCrawley has recently found what appears to be a parasitic protozon in the smears made from female cattle ticks and from crushed eggs which they had deposited. He believes it to be a stage in the life history of P. bigeminum. The Journalof Parasitol- ogy, Vol. 11 (1915), p.
