88 EXPERIMENT STATION RECOKD. 



Diagnosis of glanders, C. Thokstek (Ztxdir. \'ctevinark., 14 [lU(i.i), A'o. 8-u^ iqi. 

 ,VJ-374). — In the autlior's exi)erience the inoculation of male j^ninea pigs Avith 

 material .suspected of being glanderous does not furnish a sufficiently ra])id and cer- 

 tain means for diagnosing glanders. The results are often uncertain on account of 

 the frequent death of guinea pigs from septicemia and intermittent diseases. When- 

 ever the results are unsatisfactory it becomes necessary to repeat the cultures of the 

 suspected material, and juuch time is thus lost. 



Serum inoculation against pneumonia in horses and its value from a prac- 

 tical standpoint, Wai.tmkk (Ztxelir. }'('ferinark., 14 (J90,^), Xn. 11, pp. 500-507). — 

 The author concludes from his own experiments and those of others that the best 

 method of supin'e.s(.;iug outbreaks of pneumonia among army horses is to subject all 

 the horses of the scjuadron to serum inoculation. When carefully performe<l, this 

 oiieration is usually successful ami does not entail the loss of much time. 



Contagious coryza of horses of the remount station, Becher {Ztaclir. Veteri- 

 viivh., 15 [1903), No. 1, pp. 11-lS) . — Despite the best care and treatment which could 

 be given to horses suffering from this disease, it was found that a large proportion of 

 the patients suffered from a complication of chronic gastro-enteri(> catarrh after 

 recovery from the symptoms of contagious coryza. 



Fibro-epithelial neomorphs of the skin, liver, and lungs in horses, Tetzner 

 {Zt.^rlir. VrlerUii'irl., 14 (190,:!), Xo. 7, 2>p. 296-.U0, pJs. I'h— The ])resent article is 

 occupied with an account of the fibro-e])itlielial neomorphs in the lungs. The 

 etiology anl microscopic anatomy of these structures are describeil in detail. 



The action of the poisonous principle of Equisetum, Lidewk; [Ztschr. 

 Veierinark., 14 (1902), Nos. 10, m>. 44:7-461; 11, pp. 483-493) .—Dwrm^ the author's 

 numerous experiments with these plants it was found that Equisetum Ihnosvm was 

 very dangerous to horses, while cattle and sheep could eat it without harm. The 

 converse was true for E. pahistre. It is believed that the contradictory results 

 obtained in the investigation of these plants by various authors are to be explained 

 hy the assumption of a coufusion of species. A chemical investigation showed the 

 presence of an alkaloid in both species. Aconitic acid was also found in varying 

 quantities. This substance occurred partly in insoluble condnnation with lime and 

 partly in an easily soluble form of an alkaline salt. 



Poisoning by Equisetum, AVuxsch {Ztsdir. Veterinark., 14 {1902), No. 10, p]>. 

 461-407). — Notes are given on a number of cases of poisoning from this plant which 

 were observed among horses. Some of the horses were affected but slightly, while 

 others died. The various lines of treatment, such as administration of calomel, 

 arecolin, eserin, spirits of camphor, iodid of potash, strychnin, etc., were without 

 apparent effect. 



Sorghum poisoning, W. Maxwell [QiAcendaiid ^[yr. Jonr., 12 {1903), No. 3, pp. 

 172, 173). — A brief preliminary report upon investigations which are being conducted 

 with various crops to determine the presence or nonpresence of certain poisonous 

 bodies. As far as the work has been prosecuted it appears not to be safe to give 

 cattle free access to sorghum imtil the seeds begin to develop. The younger stages 

 appear to be more poisonous. 



Some conditions of stock poisoning in Idaho, H. B. Slade [Iihtho Sta. Bvl. 

 37, pp. 157-190, ph. 2, figs. 3). — A general discussion is presented on the nature of 

 poisonous plants and the conditions under which poisoning occurs. The statements 

 are largely based on European and American literature on this subject. From the 

 replies to a circular letter distrilmted to stockmen it is estimated that the stock pois- 

 oned by plants during the past year in Idaho aggregated a value of $50,000. Most of 

 the shee]) lost in the State were poisoned by lupines. The author discusses the pop- 

 ular and scientific remedies which have been used or can ]>e recommended in pre- 

 venting fatal effects of plant poisoning. As a general remedy a mixture of potassium
