were fumigated with sulphur, the beds disinfected with a solution of 

 corrosive subUmate in boiling water, and old clothes burned. As a 

 result the disease disappeared from a row of badly infected coolie huts 

 for several years. It is also known that bed-bugs can live for many 

 months without food so that the clinging of the infection to houses 

 harbouring them is not surprising. On the whole the bed-bug theory 

 best accounts for all known facts, including a few instances of infection 

 of Europeans through cohabiting with native women suffering from 

 kala-azar.

Two traps are described which the author believes to be very efficient 

 for catching flies. The first consists of a trough of 10 to 20 gallons 

 capacity, half-filled with water with 10 to 201b. of iron sulphate in solu- 

 tion. Supported by means of two iron rods placed over the trough 

 is a cage of \^dre-netting, in which are put pieces of meat, fish, etc., 

 to attract the flies. The insects congregate on the meat to oviposit, 

 and the larvae which eventually hatch out mostly fall into the iron 

 sulphate solution below and are killed. The meat in the trap must be 

 renewed daily. 



The second trap described contains sweetened liquid to which the 

 flies are attracted, but from which they cannot escape. A wooden 

 box has several circular holes made in its sides, each about 4 inches 

 in diameter. Fitted into these holes are cones made of metallic 

 gauze, with the narrow ends inside the box. The cones open into 

 chambers which are separated from the centre of the box by wire 

 gauze. In the centre is placed a vessel containing the sweetened 

 liquid, and a band of flannel is arranged round the two cylinders of 

 wood w^hich can be revolved from time to time by means of a handle 

 on the outside of the box ; one of these wheels is at the top of the box, 

 and the other in the liquid, and the flannel band is stretched vertically 

 between them ; the flannel is kept moistened with the liquid and serves 

 to attract the flies by means of its odour. The flies enter the wide 

 ends of the cones, but can only very seldom find their way out again 

 when once inside. It is necessary to turn the handle at intervals 

 during the day to keep the flannel moist. The trap must be cleared 

 of dead flies each week. The formula for the liquid used is as follows : 

 brown honey, 20 lb. ; brown sugar, 4 lb. ; molasses or treacle, 4 lb. ; 

 water, 1| pints ; beer, | pint.
