since the two are often confused, lasts from 22 to 27 days. It can 

 live temporarily on rabbits, guinea-pigs, rats and dogs. Separated 

 from man, P. pubis soon dies, and it is quickly overcome by lack of 

 moisture and by heat, but it can live for 48 hours under water. In 

 treatment, mercurial substances are dangerous, fatty substances 

 containing xylol, benzine, etc., being preferable.

Anopheles inaculipeyinis breeds chiefly in stagnant, fairly clean 

 and sunny water, with more or less abundant vegetation and a high 

 temperature (20°-25° C), while A. bifurcatus prefers pure, cold 

 (12°-15° C), running, or often renewed water.

Experiments made to test the powers of resistance of Anopheles 

 m-acnlipennis and A. bifurcatus to picric acid in water showed that 

 lialf-grown larvae lived for a quarter of an hour in a solution of ^, 

 5 hours in a solution of ~^g, 4-5 days in xio? a week in ^j^o and in a 

 solution of e^o were able to transform to nymphs and adults.

The methodical use of strongly trypanocidal agents proved an 

 excellent means of combating tsetse infection. It has been thought 

 that the flies bite by day only, but numerous observations showed that 

 biting by night occurred with all the species met with, viz., Glossina 

 palpalis, G. morsitans, G. fusca, G. tachinoides^' and G. pallidijies. 



There were very few fatal cases of piroplasmosis among equines ; 

 the infection was due to Nuttallia. No infection was observed in 

 cattle, nearly aU the latter being immune in East Africa. 



African coast fever caused little loss. The infected zones were 

 known, and by using a 15-day dip containing arsenic 1 part by weight 

 and water 100, and placing the animals in an enclosed pasture that 

 was twice changed (as prescribed by Theiler) not a single animal was 

 lost.

 August & September 1920, pp. 369-374. 



Trypanosoma cazalboui var. pigritia is probably transmitted by 

 biting flies other than Glossina and also by mosquitos and even ticks. 

 In the Zambi district the chief vector is apparently Haematopota
