the science of medicine was the discovery that the parasite causing
malaria was transmitted from person to person by mosquitoes. Dr. Manson
describes this discovery fully in this number of the POPULAR SCIENCE
MONTHLY. This summer a crucial experiment is being made of a somewhat
dramatic character. A mosquito-proof tent has been constructed, which
is located in Italy, in the Campagna. In this Dr. Luigi Sambon,
lecturer of the London Tropical School of Medicine, and Dr. G. C.
Low will live until October, taking the utmost care not to be bitten
by mosquitoes. If they escape malaria it will serve as corroborative
evidence that the mosquito is the means of infection. On the other
hand, several Englishmen, including Dr. Manson’s son, have offered
themselves as subjects for the complementary experiment. They will
live in a healthy district, but will definitely allow themselves to be
bitten by mosquitoes which are known to be infected. These experiments
will probably be particularly useful in demonstrating to the public at
large the validity of the hypothesis derived last year from technical
bacteriological evidence.
