country. No one seems to know who invented it, but the writer first 
saw it in operation some years 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 mosquitoes, 
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 oilof pennyroyal. The use of oil of pepper- 
mint, lemon juice, and vinegar have all been recommended as pro- 
tectors against mosquitoes, while 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 by 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. ) 4 
One drop of oil of lavender on pillow, and one on the head at night. (A. E. S.) 
Tincture of Ledum palustre. (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 ammonia. (P. G. L.) 
Eucalyptus oil. (X.) 
Same substance. (Dr. George Cohen.) 
Oil of eucalyptus and creosote, each 5 drops, to be thoroughly 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, but 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 IJ. 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 inadry 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.
