Statistics are given of the malaria cases attended to and the quinine 

 distributed in the northern Argentine provinces during the first six 

 months of 1919 under the anti-malarial laws. The staff of the anti- 

 malaria campaign also collaborated in the measures taken to subdue 

 plague and typhus in the same provinces. In attempting to control 

 malaria, attention is drawn to the difficulties, in spite of extensive 

 funds, arising from the magnitude and topography of the regions 

 dealt with, the economic poverty of the provinces, the social habits 

 of the population, etc. In any case endemic malaria can only be 

 controlled by systematic and continuous efforts over a long period.

 von Lausen und Flohen. [Sulphurous Acid for kilhng Lice and

Fleas are very susceptible to sulphur dioxide, their larvae and lice 

 are somewhat less so, and the eggs of lice are still more resistant. 



In a room of 40 cu. metres capacity (1,400 cu. ft.) at a temperature 

 of 12°-20° C. (52°-68° F.) and containing a batch of clothing (weighing 

 about 154 lb.) but otherwise empty, and with gas taken from a 

 cylinder of liquid SO^, lice and their eggs were killed in 4 hours when 

 SO., was present at a strength of 2| per cent. ; 4 per cent, proved 

 fatal in l|-2 hours, even when the articles were packed in a laundry 

 basket and well covered. The operator runs less risk of infestation 

 if the garments have not to be spread out. 



Under similar conditions, but using burning sulphur, a strength 

 of 2^ per cent. SO., proved insufficient in 4 hours. Using burning 

 salforkose (90 per cent. CS^, carbon bisulphide), 3 per cent, of SO., 

 also proved ineffective and higher strengths are necessary. An 

 equal strength of gas from cylinders is therefore more effective ; 

 whether this is due to impurities in the product from burning sulphur 

 or CS.2 is not known. The opposite result is obtained in the case of 

 bacteria. Rooms at low temperatures such as 12°-14° C. (52°-57°F.) 

 must be warmed before fumigation. 



In cupboards almost filled with garments 44 per cent. SO.^ will 

 destroy fleas and lice in one hour, but for such a strength the gas 

 must be obtained from cylinders.

This is an illustrated description of a manure pit at the Pasteur 

 Institute in Algiers. Built in 1912, it comprises twin pits of ferro- 

 concrete. These are raised on pillars so that a cart may be placed 

 beneath them for subsequent removal of the manure. This is thrown 

 into one of them twice a day by means of a trapdoor in the top. 

 Fermentation results in a high temperature— 201° F. (94° C) in the
