Hall (M. C.) & Avery (L.). The use of Carbon Bisulphid in 

 Infestations with Bots, Gastwphilus spp. — Jl. Amer. Vet. 

 Med. Assoc, Baton Rouge, La., Ivi, no. 3, December 1919, 

 pp. 265-270. 



Experiments made to ascertain the minim am efiective dose of 

 carbon bisulphide for the removal of bots in horses show that single 

 doses of 6 drachms or 2 doses of 4 drachms each given at an interval 

 of two hours will remove all species of Ga&irophilus from the stomach 

 and duodenum ; three doses of 3 drachms each at intervals of 1 hour 

 are equally effective. Smaller doses will remove G. mtestinalis from 

 the cardiac stomach, but are not efiective against G. nasalis owing to 

 the location of the larvae of this species, as apparently by the time 

 the drug reaches the pylorus, it has been partly absorbed and diluted 

 with the fatty contents of the stomach, its lethal action being thus 

 reduced. If purgatives are given they should be administered several 

 hours, at least, before or after the drug. The use of linseed oil 

 diminishes the efficacy of carbon bisulphide against Gastrophilus. 

 The work of previous authors on this subject is reviewed. 



WoLLMAN (E.). Larves deMouche {CallifJiora vomitoria) et Vitamines. 

 ~-C. B. Soe. Biol, Paris, Lxxxii, no. 29, 22nd November 1919, 

 pp. 1208-1210. 



Further investigations have been made concerning the hypotheses 

 suggef.ted in a previous paper [R.A.E., B., vii, 140]. Lar^^ae of 

 CallipJiora vomitoria thrived well even when fed on brains that had 

 been sterilised at a heat of 134° to 135° C. [273°-27o° F.] for U hours. 

 The larvae treated in this manner were noticed to develop rather 

 more slowly than usual during the first 2 days, but by the 6th or 

 7th day they had reached their normal size and pupated as usual from 

 the 8tii to 10th day. 



Sterilisation even at a temperature of 134° C. does not appear 

 therefore to destroy the vitamines of certain foodstuffs. It is not 

 thorght probable that the larvae themselves create vitamines, but 

 rather that they accumulate and concentrate those present in their 

 diet.

The author gives the following summary of this paper :— Anti- 

 typhoid inoculation has been reported to reduce susceptibility to 

 malaria. Lnteric fever in Jamaica is a severe affection with com- 

 paratively high mortality. Malarial infection in Jamaica is also 

 a severe condition ; in a large majority of cases it is of the subtertian 

 variety. Qi inine does not have any marked effect on uncomplicated 

 cases of enteric fever. The serum of patients suffering from un- 

 complicated malarial fever will not give a positive reaction to Widal's 

 agglutination test. Coincident enteric fever and malaria (that is, 

 Mhen a patient is seen early in the attack of enteric fever and 

 examination of the blood reveals the presence of malarial parasites 

 a+ this earl}' stage) in many instances at least is remarkably mild
