MODELS OF MOSQUITOES 91 Mnseum, Cromwell Boad, are models of mos- quitoes twenty-eight times as large (linear measurement) as the original insects, which are placed beside them for comparison for educational purposes. The common mosquito {Culex pipiens) which we frequently see on our window-panes does not transmit the malaria parasite. The spot- winged mosquitoes (Anopheles maculipennis), abundant in England and nearly all parts of the world, are carriers of the malaria parasite. The parasite multiplies not only in the human blood, but in the stomach and tissues of the mosquito. Various forms of malaria are distinguished by medical men according to the frequency of the recurrence of fever and other symptoms, as Tertian, Quartan, &c. Each is due to a distinct species of parasite, though the differences are very slight. The life-history represented by the models referred to is that of the parasite of the so-called ' pernicious ' or * sestivo-autumnal ' malarial fever. The malaria parasite is an ; iiii ' 1|.
