The authors present a note on the abihty of the above bacillus to re-tain its virulence when kept under artificial cultivation over a longperiod. Inoculation of 1 cc. of a mixture of eight strains, represent-ing only one-fifth of an agar slant, produced typical abortion in a mareprotected with 200 cc. of hyperimmune serum. The strains used inthis experiment had been isolated for periods varying from three tofive years.—H. W. L. Studies to Diagnose a Fatal Disease of Cattle in the Mountainous Regions of California. K. F. Meyer. Jour. Am. Vet. Med. Assoc, 1916, 48, 552-560. Discussion of the subject is divided into symptomatology, anatomicalfindings, bacteriological examinations and epidemiology.
