odour of this oil drives away all Diptera Brachycera and the deodorant 

 power of the product largely reduces the stench of putrefying matter. 

 The emulsion may be sprayed from hand-sprayers or from those in 

 which carbonic acid gas actuates the jet, which may then reach as 

 far as from 24 to 30 feet. This provides a means of spraying bodies 

 at some distance in front of a trench without attracting the attention 

 of the enemy.

The Lotrionte method of destroying Daciis oleae (olive fly) [see this 

 Review, Ser. A, ii, p. 289, p. 452] is also efficacious for ordinary flies 

 and horse flies. In stables, manure heaps, etc., the flies and their eggs 

 may be destroyed by spraying with a solution containing : water, 

 100 parts by weight ; molasses, 10 parts ; and either arsenite of potash 

 or arsenite^ of soda, 2 [jarts. The " capanette," peculiar to the 

 Lotrionte method, should be used in houses.

To destroy lice on domestic animals, i lb. of ordinary soap, and 2 oz. 

 of snuff tobacco are boiled in about 20 quarts of water, till the whole 

 of the soap is dissolved ; 4 quarts of kerosene are then added to the 

 boiUng solution, stirred and allowed to cool into a jelly. For use, 

 1 part of this jelly is dissolved in 9 parts of warm water and rubbed 

 into the coat of the animals with a piece of cloth ; four or five days 

 after the second application all the lice disappear.

In these lectures, the noxious trypanosomes of man and animals 

 in Central and Southern Africa are considered. The conditions 

 which obtain on the East and West Coasts of Africa between 20 deg. N. 

 and 30 deg. S. latitude are much the same as those which are 

 found in the central parts, and it is probable that the same trypano- 

 somes are found throughout. In describing the species found in the 

 British Colonies, it maybe assumed that all the important pathological 

 species found in Central Africa are being dealt with, although in other 

 places they may be known by other names. In the north of Africa, 

 outside the range of the tsetse-flies, two trypanosome diseases are 

 found, one of the horse, (dourine) and another of camels (surra), the 

 former conveyed from sick to healthy horses by contagion,.. the latter 

 almost certainly by Tabanidae.. The wide distribution of these 

 haematozoa is shown on a map of the world, and for the purposes of 

 classification, the morphology of the various species of trypanosomes,
