desirable. The author is doubtful whether Glossina should be con- 

 sidered to be the only carrier, and instances a case in which five animals 

 were afTected under circumstances which rendered tsetse transmission 

 doubtful. The year's outbreaks, contrary to those in previous reports, 

 have not been in working oxen, which may pass through possible areas 

 of infection, but have been confined to herds of breeding stock, chiefly 

 small ones kept for dairy purposes. Of diseases transmitted by ticks, 

 anaplasmosis has been found to occur in the Lower Shire, Blantyre, 

 Zomba and Mlanje Districts, being particularly fatal during the dry 

 season, when the animals are in low condition owing to scarcity of food. 

 At other times digestive disorders show the presence of these parasites 

 in the blood cells. Anaplasma centrale is not common. It was the 

 rule to find a mixed infection of anaplasmosis with Babesia ynvtans, 

 which is one of the commonest parasites met with in the blood of 

 animals in the Shire Highlands and Lower Shire areas. Native 

 animals are very immune, the mortality being usually under 5 per 

 cent., though this figure is occasionally exceeded under adverse 

 conditions. A case of Babesia theileri is reported from North 

 Nyasa, where the disease is presumed to be endemic. The author 

 strongly urges the advantages accruing from dipping. Two spraying 

 machines are available for public use. Cooper's improved cattle dip 

 is used in these in solutions of 1-200 for the weekly dip and 1-300 

 for a 3 days dip. Private tanks have also been built.

In previous papers the morphology of Trypa7ioso)na simiae and its 

 action on animals have been described. In the present paper an 

 account is given of its development in Glossina morsitans, which can 

 transmit it from infected to healthy animals. T. simiae multiplies 

 in the intestines and in the labial cavity of the proboscis of the fly, 

 and here only developmental, not infective forms are found, there 

 being no specific characters by which these forms can be distinguished 

 from other pathogenic trypanosomes found in tsetse-flies. The final 

 stage of development takes place in the hypopharynx, where the 

 infective form of the parasite, similar in shape to the trypanosome 

 found in the blood of infected animals, is produced. The flies do not 

 become infective until about twenty days after their first infected 

 feed.
