and the skin became covered with thick crusts of dried pus. Postmortem examina- 

 tion showed no changes in the internal organs. Pustulous inflammation of the 

 skin in cattle can also give rise to inflammation of the lymph vessels; the abscesses 

 thus forming do not, however, break open. The clinical picture then coincides with 

 that of the skinworm (streptothrix fareinica) of cattle (A-'ol. I) (Lienaux, Ann., 

 1902, 237). 



Other Pustular Inflammations of the Skin. Kiiniper and Schumann ob- 

 served a contagious exanthema in military horses affecting the region of the 

 rectum and perineum and on the under surface of the tail, in mares also on the 

 vulva (Fig. 12S). It was not accompanied by itching or by general disturbances 

 of health. Vesicles occurred at these places as large as mustard seeds, peas or

 ish fluid. In a very short time these changed to elevations, turned brownish red 

 in color covered with crusts and depressed in the center, which continued to exude 

 a yellowish fluid after the crusts had fallen ofl'. The disease could not be transmitted 

 to healthy horses by inoculation, Init Kiimiier nevertheless was of the opinion that 

 it was transmissible by means of the cleaning utensils. In an enzootic among 

 remounts the disease could be traced with great probability to a cleaning cloth soiled 

 by petroleum or rancid hoof grease. (Kamper, Z. f. Vk., 1903, 440. — Pr. Mil. Vb., 

 1908.— Schumann, S. B., 1906, 186.) 



Scheferling saw an epizootic skin disease, at maneuvers and also in military 

 horses, which could not be transmitted artificially and which was characterized by
