in the number of cattle, as there is no recognisable increase in the. 

 number of tsetse-fly in these areas and no extension of their range. 

 A serious extension of the Glossina area is, however, reported in the 

 Lomagundi district. 



Compulsory Dipping Ordinance. — Rhodesia Agric. Jl, Salisbury, xi^ 

 no. 6, August 1914, pp. 854-856. 



A new law, the Compulsory Dipping Ordinance, renders the dipping 

 of cattle, and such other animals as may be prescribed, compulsory 

 on the commonages of towns and villages and enables compulsory 

 dipping to be apphed in any rural area, where such is the wish of the. 

 majority. Owners will be required to provide dipping tanks, but 

 Government assistance will be given where this is impossible. 



Paranaphand Scalo. — Agric. News, Barbados, xiii, no. 322, 29th August 

 1914, pp. 282-283. 



Paranaph [see this Review, Ser. A, ii, p. 697] seems to be of great 

 value as a tick wash or spray, especially when mixed with a special 

 tick preparation. The following is said to give good results :; 

 Paranaph 5 lb., Cooper's Dip 5 oz., water 3 gallons. The paranaph 

 is dissolved by stirring in 2| gallons of water and the dip is dissolved 

 separately in 1 quart of water and then added. It has been stated 

 that 1 oz. of commercial arsenite of soda may be used in place of the 

 5 oz. of dip. A hand syringe with an Abol nozzle is recommended 

 for applying this mixture to tick-infested cattle, from 1| to 2 quarts 

 being required for each beast. This mixture is said to kill all the 

 ticks on the animal at each application, if carefully used as directed. 



HuTCHEON (D.). Bots or "Paapjes". — Agric. Jl. Union S. Africa^ 

 Pretoria, viii, no. 2, August 1914, pp. 194-200. 



This paper, which is intended for the general information of farmers, 

 deals almost entirely with the horse bot. The larva of Hypoderma 

 [Oestrus) bovis has not been met with in Cape Colony, except on cattle 

 imported from Europe. Sheep and goat bots are frequently found in 

 the frontal sinus and the larvae of another species have been found 

 in Cape Colony, in the skins of Angora goats imported from Asia Minor,, 

 but do not appear to have bred there. Farmers report that, though 

 very little attention was given to the destruction of the larvae so 

 imported, the flies never appeared, and it is probable that as the larval 

 stage is completed in the host at the beginning of the Cape winter, 

 instead of the beginning of summer as in Europe, the climatic condi- 

 tions are not favourable to the development of the imago and the- 

 propagation of the species. Many South African antelopes suffer 

 from bots of different species, and several others infest different parts, 

 of the intestine of the horse, but the common Gastrophilns equi is the 

 species of most importance in the Colony. The favourite local method 

 of treatment is as follows : — The horse is starved for 24 hours and then 

 given a pound of brown sugar, dissolved in a quart of milk. This is 

 supposed to loosen the hold of the bots on the gastric mucous membrane. 

 After an hour or two a pint of strong tea is given, followed by a pint of
