 Anofele. [The Result of a small Drainage Scheme and the Spread 

 of Anophelines.^; — Policlinico, Sez. Prat. 1921, no. 4. (Abstract

Cases of malaria were observed in dwellings close to more or less 

 water-logged quarries, while others about 600 or more yards away 

 remained immune. As a result of very rainy seasons the quarries 

 became swamped and malaria became the predominating disease in 

 the neighbouring houses. Oiling gave good results, bnt the drainage 

 and drying up of the quarries effected a radical cure. 



This case led to an examination of the question of the radius of 

 influence of an Anophehne centre. It may be said that in practice 

 small centres extend their influence to under 600 yards, while the 

 large ones may do so up to 1,100-1,650 yards. The spread of malaria 

 may be considered to be due to successive stages of travel by successive 

 generations and not to an extended migration. To admit the latter 

 would lead to the assumption that rural districts may be breeding 

 places from which the Anophelines take neighbouring towns as their 

 objectives — a phenomenon that does not occur in practice. 



This case also shows the value of reclamation work on a small scale, 

 it may be that many small efforts of a similar nature may prove more 

 efficient than huge programmes that are difficult to carry out.

In the State of Jalisco and the surrounding region, comprising 

 the greater part of the north-western States of Mexico, stock-raisers 

 lose thousands of heads of cattle every year from some disease, the 

 nature of which is not exactly known, and for which no remedy has 

 been found. The diseased cattle are generally free from ticks, and 

 the author has been unable to detect any parasite or other organism 

 that might be the causal agent. The popular belief is, however, 

 that biting-flies are responsible for the high rate of mortality, and it 

 has frequently been observed that after a bite from a fly animals 

 show signs of disease and eventuall}^ die. The symptoms of the 

 disease are described, and the author is inclined to ascribe them to 

 trypanosomiasis, as almost certainly some blood parasite is the cause.

Azurophil gramflations as studied in constituents of the body fluid 

 of adults of Carausius morosiis and the larvae of Gallcria mellonella 

 present the same properties as similar constituents of human blood.
