EouBAUD (E). Rythmes physiologiques et Vol spontan6 chez VAno- 

 pheles maculipenni^. [Physiological Rhythm and spontaneous 

 Flight in Anopheles macuUpennis.] — C. R. hebdom. Acad. Sci., 

 Parts, clxvii, no 24, 9th December 1918, pp. 967-969. 



The flight of Anopheles macuUpennis seems to respond to certain 

 laws with a mechanical precision. In the laboratory it remains motion- 

 less, apparently insensible to abrupt alternations of light and darkness, 

 during the whole day, but at the beginning of twilight it suddenly 

 springs into full flight. This takes place always at the same time, 

 so exactly that it is possible to regulate one's watch by it, if the light 

 conditions remain the same. The period of flight, which is the 

 dangerous time from a malarial point of view, never extends in 

 captivity beyond the first two hours of the night, throughout the 

 rest of which the mosquito remains motionless, showing no tendency 

 to become active at dawn. Under normal conditions, therefore, 

 A. macuUpennis passes 20-22 hours of the 24 in a state of complete 

 repose. 



Croll (D. G.). Filariasis among Australian Troops. — Brit. Med. Jl., 

 London, no. 3027, 4th January 1919, p. 28. 



Of 4,000 Europeans admitted to Brisbane hospital in 1909 and 

 1910, 11 "5 per cent, were found to be suffering from filariasis, though 

 practically none of them showed symptoms of the disease, nor did 

 they appear to suffer any inconvenience from the parasite in the 

 blood. From this it may be concluded that about 10 per cent, of 

 the population of southern Queensland are thus infested. Symptoms 

 of the afEection are, however, comparatively rare, though cases of 

 filarial lymphangitis, chyluria, and filarial adenitis are occasionally 

 seen. Cases of hydrocele, lymphocele, and deep intramuscular 

 abscesses of obscure origin are notably prevalent, but filaria can rarely 

 be found in the blood in these cases. Elephantiasis is unknoAvn. 



Various methods have been tried in Queensland to abolish the para- 

 site from the blood, but none have as yet proved to be of definite 

 value. It is found that the parasite disappears from the blood in 

 about 4 years if there is no re-infection. The most successful prophy- 

 lactic measure is the systematic use of mosquito nets,

The capture of Anopheles plumbeus (nigripes) in Dauphine and the 

 Pyrenees is recorded [see also this Review, Ser. B, vii, p. 29].

 France. — Rev. Scient., Paris, Ivii, no. 3, lst-8th February 1919, 

 pp. 84-85. 



Infantile kala-azar exists in France, at any rate on the Mediterranean 

 coast adjoining the Italian frontier. It is supposed that the two 

 children at Nice whose cases are here cited contracted the disease 

 from infected dogs, canine leishmaniasis being known to occur on the 

 Mediterranean coast from Marseilles to the Italian frontier.
