organs, as there was so much post mortem staining. The hYsli was, if 

 anything, brighter than normal, with a yellowish-red color. Micro- 

 scopical examination failed to reveal any germ, excepl a few putrefactive 

 bacteria, and, as the animal had been dead bo long, T could not give a 

 definite opinion, hut considered the lesions almost identical with th - 

 of Texas or Southern fever. 



"It would seem, in this case, that the infectious principle came from 

 the Poly-Heilbron ranch, and that the other deaths reported by Dr. 

 Davidson were due to infection in passing over the Poly-Heilbron ranch, 

 or they were infected before leaving the Salinas Valley; hut the former. 

 in my opinion, is the more likely, as the number of death- at tie Poly- 

 Heilbron ranch during the past few months would indicate considerable 

 infection in that locality. 



" Finding the death-rate at a minimum, and no other place- to visit, 

 I returned to San Francisco." 



In February, 1889, Governor Waterman, of California, telegraphed 



that the disease was still prevalent among cattle in San Diego County, 

 and asked that a competent veterinarian be directed to make a further 

 investigation, and give such directions as might prevent its extension 

 and ultimately result in its suppression. In compliance with this 

 request, Dr. A. J. Chandler, veterinary surgeon for the Territory of 

 Arizona, was directed to visit the locality. The results of his investi- 

 gation will lie found embodied in the following report: 



"Upon receipt of your telegram I at once started for Southern Cali- 

 fornia, and while in Los Angeles accidentally learned of the district in 

 San Diego County in winch the disease existed, which proved to In- on 

 the Los Penasquitos ranch, about fifteen miles north of San Diego, five 

 miles back from the coast, and leased by Governor Waterman. Upon 

 investigation I found that about one hundred head of cattle had been 

 affected with the disease, some thirty of which had died. Among the 

 latter were some very valuable Hereford hulls. A number were on a 

 fair way to recovery, while a few were beyond hope. The disease is 

 undoubtedly Southern fever. I mad< two post mortem examinations, 

 one upon an animal which had died just before my arrival, and the 

 other upon an animal I had slaughtered. In both instances the spleen 

 was enlarged, the liver yellowish-brown and increased in weight) the 

 gall-bladders were enormously distended and tilled in one case with 

 yellowish fluid bile, and in the other with a dark brown and very thick 

 fluid. The urinary bladders were Idled with dark, bloody urine. The 

 kidneys were congested and enlarged, and the cortical substance soft- 

 ened; the subcutaneous alveolar tissue and the mucous membranes ^i 

 a yellowish tinge. The blood fluid was of a bright red color. The 

 symptoms are high temperature, rapid pulse, staggering gait, and in 

 some instances delirium. The following history of the outbreak ie thus 

 given: 



" In April, 1SSS, eighty- four head of cat t Ie were driven across count ry 

 from the Penasquitos ranch to San Bernardino. In .Inly, part of the 

 same herd, and cattle from thedairy ranch atSan Bernardino seventy- 

 three head in all were driven to the Penasquitos ranch. Two weeks 

 after they reached i he ranch they commenced dying. Those coming
