were coughing, so I recommended for each affected animal the f ollow- 



Spirits of turpentine, 1-J ounces; linseed oil, 1 pint, Mix and make 

 one drench; give immediately. 



I considered this the safest thing to give them, as it would be impos- 

 sible to give inhalations, and I had no inter-tracheal syringe with 

 me. 



The next autopsy was a calf that died two days before I arrived. 

 The weather was cold, and there was not much decomposition. The 

 spleen was enormously enlarged, being at least three times its natural 

 size, and on section was black, but not entirely disintegrated. The liver 

 was enlarged, fatty, and of a brick-red color; the gall-madder was 

 distended to a great size, and full of gall. I did not examine the 

 other organs, as there was so much post-mortem staining. The flesh 

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

 Microscopical examination failed to reveal any germ, except a few 

 putrefactive bacteria, and as the animal had been dead so long I 

 could not give a definite opinion, but considered the lesions almost 

 identical with those of Texas or Southern fever. 



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

 Polly Helbrun's ranch, and that the other deaths reported by Dr. 

 Davidson were due to infection in passing over Polly Heibrun's 

 ranch, or they were infected before leaving^ the Salina Valley; but 

 the former, in my opinion, is the more likely, as the number of 

 deaths at Polly Helbrun's during the past few months would indi- 

 cate considerable infection in that locality. 



Finding the death rate at a minimum and no other places to visit, 

 I returned to San Francisco. 



Very respectfully submitted*

SAN FRANCISCO, CAL., December 13, 1888. 



FURTHER INVESTIGATION BY DR. A. J. CHANDLER. 



In February, 1889, Governor Waterman, of Calif ornia, telegraphed 

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

 and asked that a competent veterinarian be directed to make a fur- 

 ther investigation and give such directions as might prevent its exten- 

 sion, 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 in- 

 vestigation will be found embodied in the following report: 



Upon receipt of your telegram I at once started for southern California, and 

 while in Los Angeles accidentally learned of the district in San Diego County in 

 which the disease existed, which proved to be on the Los Penasquitos ranch, about 

 15 miles north of San Diego, 5 miles back from the coast, and leased by Governor 

 Waterman. Upon investigation I found that about 100 head of cattle had been 

 affected with the disease, some 30 of which had died. Among the latter were some 

 very valuable Hereford bulls. A number were on a fair way to recovery, while a 

 few were beyond hope. The disease is undoubtedly Southern fever. I made two 

 post-mortem examinations, one upbn 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 filled in one case with yellowish fluid 

 bile and in the other with a dark brown and very thick fluid. The urinary blad- 

 ders were filled with dark bloody urine. The kidneys were congested and enlarged
