Mosquito or Man? By Sir Rubert Boyce, F.R.S. (John Murray.
10s. 6d. net.)—A full account of the researches which have resulted in identifying the causes of malaria with the bite of an insect or insects which are sufficiently described by the name of mosquito. The volume is, of course, full of technical detail, but its subject is profoundly engrossing, not to the student of medicine only, but to all who have an interest, direct or indirect, in travel, residence, or occupations which these influences affect.
