country. No one seems to know who invented it, but the writer first 

 saw it in operation some 3 ears ago in New Jersey, and was struck with 

 its simplicity and efficacy. The top of a tin baking-powder box is 

 inverted and nailed to the end of a stick of sufficient length to reach 

 to the ceiling. A small quantity of kerosene is put into this impro- 

 vised cup and the apparatus is pushed up under resting mostiuitoes, 

 which fall into the kerosene and are destroyed. It is the custom in 

 certain houses to systematically hunt for mosquitoes in the bedrooms 

 with such an apparatus every night before retiring. 



Camphor rubbed on the face and hands or a few drops upon the 

 pillow at night will keep mosquitoes away for a time, and this is also 

 a well-known property of oil of pennyroyal. The use of oil of pepper- 

 mint, lemon juice, and vinegar have all been recommended as pro- 

 tectors against mosquitoes, whilv^ oil of tar as used against the black 

 fly in Canada is also used in bad mosquito localities. Strongly cam 

 phorated vaseline, although recommended, has been found l)y Dr. 

 Nuttall to be of scarcely any use in Canada. 



One of the London papers, the Daily Telegraph, invited its readers 

 to send in mosquito remedies of this kind during the summer of 1899, 

 and some of the substances recommended were as follows: 



Eucalyptol on the skin, with a handkerchief .saturated with it placed on the pillow 

 at night — the result of South African experience. (Arthur E. Edwards.) 



Carbolated vaseline. ( Dr. George Mackern. ) ^ 



One drop of oil of lavender on pillow, and one on the head at night. (A. E. S. ) 



Tmcinre oi Ledum palustra;. (M. Fisher.) 



Piece of cotton wool soaked in oil of cloves on each side of the bed curtains. 

 (W. B.) 



Anoint skin with 3 parts refined paraffin and 1 part crushed camphor. (W. T. 

 Catleugh. ) 



To heal the bites, a drop of liquid anunonia. (P. G. L.) 



Eucalyptus oil. (X.) 



Same substance. (Dr. George Cohen.) 



Oil of eucalyptus and creosote, each 5 drops, to l)e tlioroughly mixed with 1 ounce 

 of glycerin. (R. R. P. S. Bowker.) 



Place a fine, juicy, uncooked beefsteak near the bed on retiring. (M. M. M.) 



A substance with which the writer is not familiar, hut which is 

 spoken of very highly in the interesting paper by the Italians Celli 

 and Casagrandi in a paper -to which we shall have occasion to refer 

 later in speaking of remedies against the larva, is a yellow aniline color, 

 referred to in the work of the Italians as Larycith III. They state 

 that a little of this substance burned will kill the adult mosquitoes 

 and that this method constitutes the most efficacious means of destroy- 

 ing them. The Chinese use pine or juniper sawdust, mixed with a 

 small quantity of brimstone and 1 ounce of arsenic, run into slender 

 bags in a dry state. Each bag is coiled like a snake, and tied with 

 thread. The outer end is lighted. Two coils are said to be sufficient 

 for an ordinary room, and 100 coils sell for 6 cents.
