ZiBORDi (D.). The Toxicity of the Extract of the Horse-Bot {Gastro- 

 philus cqiii). — La Clinica Veterinaria, Milan, xliii, nos. 17-19, 

 15th & 30th September, 15th October 1920, pp. 470-476. (Abstract 

 in Internat. Rev. Sci. & Pract. Agric, Rome, xii, no. 5, May 1921, 

 pp. 587-588). [Received 15th February 1922.] 



The symptoms produced by the injection of the extract of horse 

 bot-fly larvae {Gastrophilus equi) in particular, and of that of all 

 parasites in general, are due to poisons which may attack the cerebro- 

 spinal nervous system by preference, and, at the same time, have 

 an action on the heart, almost like a specific cardiac toxin ; further, 

 according to Weimberg and Seyderhelm, they may have a haemolytic 

 effect similar to that of a haematic toxin. 



Kretzschmar ( — ). Treatment of Sheep Scab by Sulphur Dioxide 

 Gas. — Deutsche Landw. Tierzuchf, Hanover, xxiv, no. 40, October 

 1920. (Abstract in Internat. Rev. Sci. & Pract. Agric, Rome, 

 xii, no. 5, May 1921, pp. 589-590). [Received 15th February 

 1922.] 



With the revival of sheep breeding in Germany, sheep scab has again 

 spread rapidly. Sulphur dioxide has proved signally successful in 

 treating this form of mange. An apparatus for fumigating sheep with 

 this gas is described. It is in the form of a large wooden box, weighing 

 about 1,000 lb., and holds four animals. It is fitted with india-rubber 

 collars through which the animals' heads emerge. Shorn individuals 

 require 50 minutes' treatment with 4 volumes per cent, of sulphur 

 dioxide fumes ; if the sheep are unshorn, a 4| per cent, concentration 

 must be used for the same time. 



EuGLiNG (M). Ueber Malariabekampfung. Beobachtungen und 

 Untersuchungen aus dem albanischen Malaria-Gebiet. [Malaria 

 Control. Observations and Researches in the Albanian Malaria 

 Region.] — Beihefte Arch. Schiffs- u. Trop.-Hyg., Leipsic, xxv, 

 no. 1, 1921, 63 pp., 6 figs. [Received 15th February 1922.] 



WTien Albania was occupied in 1916 by the Austro-Hungarian 

 armies, 20 per cent, of the troops suffered from malaria, and 52 per 

 cent, in 1917. The mountain zone was nearly free from malaria at 

 the time of occupation, the average figure for 1917 being only 6 per 

 cent., of which many cases originated in the plains. 



Such troops and road gangs as remained in the plain and along the 

 coast suffered from malaria to the extent of 70-90 per cent., an 

 important feature being the predominance of severe malignant tertian 

 [Plasmodium praecox]. In a group of 20,185 blood examinations 

 there were 10,411 positive findings, of which 78-4 per cent, were 

 malignant tertian, 20-9 benign tertian, 0-16 quartan, and 0-54 mixed 

 infections, etc.
