 40-60 animals can be treated in both ears per hour. 



If ticks are present on a property, it is advisable to treat all animals 

 periodically, whether they show infestation or not. 



MoHLER (J. R.). Tick Eradication Plans for 1919.— JZ. American Vet. 

 Med. Assoc., Ithaca, N.Y., liv, no. 7, March 1919, pp. 745-748. 



The progress of tick eradication in the United States since 1905 is 

 briefly reviewed. It is hoped to make the year 1919 the most successful 

 there has been in this work. The need for unremitting efforts in 

 educating farmers and cattle raisers in the importance of the campaign 

 is insisted upon and it is remarked that those who still oppose tick 

 eradication are learning every day that their attitude results in 

 pecuniary loss to themselves. With the new State-wide compulsory 

 dipping law in Texas, which becomes effective in the last zone of that 

 State in 1922, it is hoped that the Federal quarantine can be entirely 

 lifted from American territory at the end of 1923. The area still 

 under quarantine is 270,036 square miles ; of this it is hoped that 

 90,000 square miles may be cleared during 1919.

 (Capt. J. A.). Preliminary Report on the Presence of a "Filter 

 Passing" Virus in Certain Diseases, with Especial Reference to 

 Trench Fever, Influenza, and Nephritis. — Jl. R.A.M.C., London^

The authors record the isolation of the virus of trench fever from 

 the blood of trench fever patients and from infected louse excreta. 

 The culture obtained either from the blood of man, or from louse 

 excreta, when inoculated by scarification into man, produces a mild 

 illness, and the organism can be recovered from the blood by culture 

 during such illness, and also from clean lice fed on the patient during 

 the illness.

 the Treatment of Domestic Animals affected with African 

 Trypanosomiasis. — Vet. Jl., London, kxv, no. 3, March 1919, pp. 

 89-103. 



As a result of experiments with various preparations, and a study 

 of previous w^ork in this connection, the conclusion has been reached 

 that on account of its solubility, low toxicity and high trypanocidal 

 action, tartar emetic is probably the most valuable drug available for 

 use on a large scale in the treatment of domestic animals affected with 

 trypanosomiasis. It is inexpensive, and can be administered intra- 

 muscularly or intravenously, though the latter method is the better. 

 One gramme every third day is the maximum that can be administered 

 over a long period to even the largest domestic animals ; the same 

 amount every fifth day is well tolerated by adult cattle and horses. 

 Administered scientifically it is capable of curing domestic animals 

 infected with certain strains of Trypanosoma vivax and T. congolense. 

 Resistant strains of these parasites may, however, frequently be
