 Moscow, no. 13, 9th April 1914, pp. 197-198. 



The author refers to the statement he made at the Conference of 

 Veterinary Surgeons in Tambov in 1908, that, according to the obser- 

 vations of foresters and woodcutters, the ticks which transmit piroplas- 

 mosis of horses live in earlv spring on Euonymus rerrxcosus. He has 

 been trying to verify this observation, but only in May 1913 did he 

 find two specimens of the tick on one bush. The bushes were growing 

 along the high road, near a pine wood ; he found the ticks at 9 a.m. 

 ■on a warm sunny day, after examining 25-30 bushes. He calls the 

 attention of veterinary surgeons to this statement with a view to having 

 it confirmed by others. He further says that, according to liis obser- 

 vations during the last two years, piroplasmosis never begins before 

 the opening of the buds of Euonynnis and birch, which statement 

 he would also be glad to have verified by others. He refers to the 

 beUef that the ticks usually attack horses early in the morning, or 

 €ven at night, so that some surgeons recommend that horses should 

 not be sent to pasture until after the dew has passed off. and he thinks 

 that it is possible that during the day the pests may pass from the 

 bushes to the ground or even into tlie soil. Some observations tend 

 also to show that piroplasmosis occurs in localities where certain 

 bushes and trees prevail, such as pine, birch, Euonynms and possibly 

 some others. In 1912, no cases of the disease were recorded in the 

 southern part of the government of Tambov, where occasional aspen 

 and oak woods are scattered over the steppes, while 237 cases occurred 

 in the northern parts of the govermnent, where there are plenty of 

 pine woods. Even within a single district where there is a difference 

 in the flora of various parts the same phenomenon is noticed. He 

 thinks it very desirable that further researches should be conducted 

 in order to decide as to the influence of vegetation on the occurrence 

 of the tick.

The usual methods are advocated to avoid malaria in Austria, 

 namely administration of quinine and the destruction of mosquito 

 larvae by oiling standing water. Experience has shown that, up to 

 the present, the former method is the more important in the districts 

 in question.
