[Report of veterinary work in California] (California Sta. Rpt. 1915, pp. 36, 

 37, 38-43). — Studies were made by I^dyard of the thread lung-worm (Dictyo- 

 caulus filaria) during an outbreak in Marin Countj- in a recently purchased 

 herd of 150 Angora goats. Embryos and ova of this nematode were kept alive 

 in wet soil for three months. It occupies the bronchi and pockets in the nasal 

 passages, death appearing to be caused through suffocation. Fumigants. tracheal 

 injections, and anthelminthics were found to be valueless a.s remedial measures. 

 It was found that mature worms do not survive vapors of chloroform for 

 longer than 3.5 minutes under laboratory conditions, and an injection of 1.5 

 cc. of chloroform into each nostril proved successful in eliminating a number of 

 the worms without any harmful effect on the host resulting. The outbreak was 

 brought under control by means of chloroform, isolation, and sanitary measures. 

 During the course of lung-worm investigations the goats were found to be 

 seriously infested by lice, which represent a new si)ecies, described by V. L. 

 Kellogg as Trichodectes hennsi. 



A practical application of a method of vaccination against chicken pox de- 

 vised at the Wisconsin Station (E. S. R., 31, p. 887) was made by J. R. Beach. 

 In a badly infected flock in which 1,177 fowls were treated only per cent 

 subsequently developed chicken pox lesions, whereas 87.5 per cent of 121 fowls 

 in the same pen left unvaccinated subsequently developed the disease. Figures 

 presented indicate that vaccination has a curative as well as a preventive value. 

 Experiments were made by J. Traum in massaging the injected area in the 

 intradermal tuberculin test. It was found in 135 cattle tested that massaging 

 in this way neither obviated nor decreased the reaction but increased it in 

 9 cases. 



Five of 7 calves immunized in 1913 against tuberculosis after the method of 

 I'earson and Gilliland, were killed, one showing tuberculous infection, one lesions 

 the nature of which was not determined, and three no lesions. C. M. Haring 

 concludes that the methods of von Behring and the modifications used by Pearson 

 and Gilliland not only failed to protect sufficiently to be of practical value, but 

 that the Pearson and Gilliland method with Culture Ravenel M is positively dan- 

 gerous in that the vaccine may in some cases transmit bovine tuberculosis. In 

 order to test the infectivity of a dairy barn, corral, and 30-acre pasture in which 

 a tuberculous herd had been kept and where several open cases of the disease 

 occurred, 25 nonreacting healthy animals were placed therein one month after 

 removal of all infected animals, the manger, water troughs, etc., being left In the 

 condition in which they were found. After an interval of 70 days the cattle were 

 tested and none reacted, and 11 were killed for beef and no lesions could be 

 found. The remaining animals were tested at the end of 6 and 12 months, re- 

 spectively, but no reactors had developed. 



Further data are given on stock diseases in the Imperial Valley (E. S. R., 26. 

 p. 482). There is said to have been less hog cholera in the valley than during 

 previous years. Dermatitis in horses, which occurs in the valley primarily dur- 

 ing hot weather, is said to improve tinder proper grooming. Excellent results
