250 CONTAGIOUS DISEASES. 



the same stud, with every meal, two ounces of the hyposulphite 

 of soda, or two drachms of the chlorate of potash. American 

 practitioners laud the hyposulphite in farcy, and say that the 

 sores require no treatment except cleanliness. 

 , The Mallein Test. — Following the example of Koch, the 

 discoverer of tuberculin, Helman of St. Petersburg success- 

 fully obtained the now recognised test for occult glanders, 

 namely " mallein," which is a glycerine extract of cultures of 

 the Bacillus mallei. This extract is sterilised by heat, and 

 attenuated to ten times its weight with a two per cent, 

 solution of carbolic acid. Thirty minims of this solution 

 injected into a glandered horse causes an elevation of tempera- 

 ture of 2° to 3° in about nine to fifteen hours. There is 

 also depression, increased rapidity of the pulse ; a swelling 

 at the seat of the inoculation, and of the nearest lymphatic 

 glands, the lymphatic vessels surrounding the spot being also 

 swollen and corded. Inoculations with mallein have no effect 

 upon healthy horses. — (See Preparation of Tuberculin.) 



STOMATITIS PUSTULOSA CONTAGIOSA OF THE HOKSE. 



The Veterinary Journal for November 1878 contains a report 

 on this disease by Professors Eggeling and Ellenberger of the 

 Berlin Veterinary College, translated from the Archiv fur 

 Wissenschaftliche unci Pratishe Thierheilkunde by G. A. B. I 

 am indebted to Dr. Fleming for the woodcuts illustrating the 

 eruptions characteristic of the disease. 



They state that during the summer of 1876 several cases of 

 a contagious disease appeared in and outside the clinic of the 

 Berlin Veterinary College, presenting phenomena similar to 

 those of variola, and chiefly affecting the mucous membrane 

 and external integument. 



Some cases outside the clinic had been declared by the 

 inspecting veterinary surgeons to be suffering, or suspected of 

 suffering, from glanders. 



Most of the patients were from four to five years old, in good 

 condition, and showing but slight indications of general illness ; 

 having on the whole a lively appearance, smooth and glossy coats, 

 and eating bran mashes with good appetites ; but whilst eating 

 hay, large quantities of saliva flowed from the angles of the mouth.
