694 EXPERIMENT STATION RECORD. 



W. Wessel {Berlin. Thierarztl. Wchnschr., 1901, No. 19, p. 287).— A. solution of potas- 

 sium iodid was made containing 10 grams in 2 liters of water. This amount was 

 injected into the milk vein or jugular vein, according to the position of the cow, the 

 milk vein being chosen when the cow was nnable to stand. Good results are reported 

 from this treatment liy the author, and it is believed that it possesses certain 

 advantages over the usual method of making an infusion directly into the udder. 



Lungworms in a large herd, N. O. Laesen [Maanedsskr. Dyrlseger, 12 {1901), 

 No. 11, pp. 427-430). — The author reports the outbreak of this disease among a 

 herd of cattle, of which 43 were affected. The disease was due to the presence of 

 Strongylus micrurus in the lungs. After post-mortem examinations of calves which 

 had died of the disease, the remaining animals were treated 3 times daily with the 

 fumes from a mixture of turpentine oil and creolin in equal parts. Of the 43 animals 

 which were affected 9 died and the others recovered slowly. 



Treatment of lungworm disease of cattle by intratracheal injection of a 

 carbolic-acid solution, W. Wessel {Berlin. Thiereirztl. Wchnschr., 1901, No. 16, pp. 

 249-252). — An outbreak of this disease occurred among a number of young cattle 

 which had been grazing on a low, wet pasture and had begun to show a considerable 

 loss of flesh in August. The symptoms indicated the presence of lungworms and 20 

 gm. of a 1 per cent solution of carbolic acid was injected into the trachea of each 

 animal. Considerable improvement was noticed in the breathing of the animals after 

 2 days, and coughing was much less pronounced. Of the 8 animals which were 

 affected, 7 ultimately recovered. Similar results were obtained from an application 

 of the same treatment in other cases of this disease. 



Lungworms in sheep and the successful treatment, Peters {Ztschr. Flei.ich it. 

 Milchi/<j., 11 {1901), No. 8, pp. 239-241). — Brief notes are given on a serious outbreak of 

 lung and stomach worms which have been observed in recent years. An outbreak 

 of Strongylus contortus occurred in a herd of 400 lambs, and the worms were found in 

 abundance in the first stomach and also in the digestive stomach. As a treatment 

 the author used picro-nitrate of potash. The salt is not easily soluble, and after 

 dissolving 0.2 gm. in 100 gm. of water, J of this quantity was given to each lamb as 

 a total dose. On the same estate an outbreak of lungworms occurred later and the 

 author treated the disease by the same method. Five gm. of the solution made by 

 dissolving 0.2 gm. of picro-nitrate of potash in 100 gm. of water was injected into 

 the trachea of each sheep. Very satisfactory results were obtained from the use of 

 this chemical. The owner of the sheep administered the same remedy by way of the 

 mouth for lungworms, with favorable results. The lungworm disease of cattle has 

 also been successfully treated in the same way. 



Diagnosis of sheep scab, F. W. Garnett ( Vet. Jour., 52 {1901), No. 311, pp. 262- 

 265, pi. 1 ) . — In making inspection for sheep scab it was found necessary to adopt a 

 convenient and relialile method which could be readily applied in all cases. The 

 author believes that external symptoms which may be recognized by the naked eye 

 are not entirely trustworthy, and relies upon microscopic examination in all cases. 

 For this purpose no attention should be given to the tissue in the center of a scabby 

 area, but a small tuft of wool should be cut from the healthy skin on the edge of the 

 scabby area. If living mites are jiresent at all, they will be found in considerable 

 numbers on such wool. 



Contributions to the study of Piroplasma equi, Lavaran ( Compt. Rend. Soc. 

 Biol. Paris, 53 {1901), No. 14, pp. 385-388, figs. 13). — This blood parasite is closely 

 related to the organism of Texas fever, and is frequently found in the blood of horses 

 in the Transvaal and other parts of South Africa. Its relationship to malaria of 

 horses is not determined. It is believed, however, by the author, to be one, if not 

 the chief, organism concerned in this disease. 



Contagious pneumonia, Butel {Rec. Med. Vet., Paris, 8. ser., 8 {1901), No. 8, pp. 

 175-177). — A general discussion of the symptoms and treatment adopted by Guille- 

 main and Cadix in the treatment of 25 cases of this disease in horses.
