Celli, A. liemarks on the Epidemiolof/y and Prophylaxis of Malaria in 

 the Liqht of Piecent Researches. ('British Medical Journal,' 1900, 

 pp. 301-6.) 



Everyone is doubtless aware of the investigations upon the causes 

 of malaria which have been conducted by some of the most eminent 

 specialists. The ' British Medical Journal ' for Feb. 10th contains 

 a number of articles upon the now proven relation of mosquitos 

 (Anoplteles) to malaria, the principal of which is that cited above, a 

 summary of three works in Italian by the same author. There are 

 also reports of the Malaria Conference in Rome, and a translation of 

 Dr. Koch's Second Report upon the work of the Malaria Expedition 

 in the Dutch East Indies. As no notice has lately occurred in any of 

 the British entomological journals, some extracts and notes may be of 

 interest. 



" Man is the temporary host, and the mosquito the definitive host, 

 of the malarial parasite. These parasites complete their asexual life 

 and prepare their sexual forms in the human blood, while they com- 

 plete the sexual cycle of life, that by which the species of the parasites 

 external to man is assured, in the middle intestine of the mosquitos. 

 It follows therefore that man and mosquitos are the sources of malarial 

 infection which circulates, so to speak, from man to mosquito and 

 from mosquito to man, and so on. In this circulation of the contagion 

 the presence of malarial man is indispensable, inasmuch as down to 

 the present time the hereditary transmission of malaria from mosquito 

 to mosquito has not been demonstrated experimentally or morphologi- 

 cally, nor have resisting parasitic forms been found in the environment 

 external to the body of the mosquito. Malaria is therefore a sypical 

 contagious disease. Where there is malaria mosquitos abound, but 

 malaria does not exist in every place where mosquitos abound." The
