286 EXPERIMENT STATION RECORD. 



sale. The general principlos of h<trsesln»eiiig are presented in connection with 

 a description of the anatomy and physiology of the foot, preparation of the 

 feet for shoeing, the various kinds of shoes, and the possible injuries from 

 defective shoeing. The problems connected with the ti-ansportation of horses by 

 sea and land are also discussed. Considerable attention is given to the geolog- 

 ical and recent history of the horse and related species. 



A glossary of technical terms is appended to the volume and also a general 

 index of the nine volumes. 



The Borna horse disease, H. Kakbiger (Landic. Wchnschr. Sachscii, 10 {1908), 

 No. 8, pp. 7J, 76'). — The so-called Borna horse disease persists in various locali- 

 ties of Saxony. The means suggested by the author for controlling the disease 

 include a sanitary supervision of the water and food and better care of the 

 horses. 



Etiology of infectious pneumonia of horses, E. Tabusso (Rev. (Jen. M^d. 

 Vet., 11 (1908), No. Li'i, pp. 177-186). — In four cases of infectious pneumonia in 

 horses the author found Pasteurella ecjui to be the pathogenic organism. It is 

 not maintained, however, that this is the only organism which may produce an 

 infectious pneumonia in horses. 



The treatment of foal lameness. Beck (Wc/nisclir. TicrhcUk. u. ViehzucJit, 

 52 (1908), No. 8, pp. I.'i5-147). — The administration of iodid of potash directly 

 to young colts affected with lameness of bacterial origin was unsatisfactory. 

 Far better results, however, were obtained from the indirect use of the drug by 

 giving it to the mares. The milk then contains a sufficient quantity of iodid of 

 potash to bring about satisfactory results in the majority of cjises. In 14 cases 

 thus treated 12 recovered entirely. The umbilical cord was treated with an 

 antiseptic solution in all of these cases. In G other cases in which no attention 

 was given to the umbilical cord but in which the mares received the iodid of 

 potash in doses of 10 gm. daily, 5 of the colts recovered after a few days. 



Experim.ental leukemia in fowls, V. Ellermann and O. Bang (Ccntbl. Balct, 

 [etc.], 1. Abt., Oriff., J,6 (1908), No. 1, pp. 4, o).— Much difference of opinion 

 has prevailed regarding the nature of leukemia in animals and man. The 

 authors had occasion to carry on some experiments with this disease in fowls. 

 It was found that during the progress of leukemia, the number of leucocytes 

 may be half as great as that of the red blood corpuscles. True leukemia in con- 

 trast with so-called infectious leukemia runs a chronic course. The modifica- 

 tion of the formula for the blood elements is not due merely to an iucrciise of 

 the white corpuscles in general. The mononuclear forms are greatly increased in 

 numbers while the polynuclear leucocytes are present in relatively diminished 

 numbers. If healthy fowls ai'e inoculated intravenously with an organic emul- 

 sion containing these leucocytes a typical case of leukemia is produced within 3 

 months. The authors are disposed to believe that leukemia will prove to be 

 infectious but the organisui has not yet lieen determined. 



Avian diphtheria and contag'ious epithelioma. A'. Fally (Ann. Med. I'cL, 

 57 (1908), No. 2, pp. 69-75). — In the experiments reported in this paper the 

 author attempted to reach a differential diagnosis between these diseases or to 

 obtain evidence as to their identity or dual nature. It is admitted that a fowl 

 may have both diseases at the same time but that recovery from roup does not 

 protect the fowl against epithelioma or vice versa. The author believes, there- 

 foi-e, that the two diseases are distinct. 



The parasitic amebse of the intestinal tract of man and other animals, 

 E. L. Walker (Jour. Med. Research, 17 (1908). No. !,, pp. S79-.',59. pis. //).— An 

 elaborate review is given of the development of our knowledge regarding para- 

 sitic amebse. The author also discusses methods of eultivatioxi of amebic.
