Treatment should be prophylactic as well as actual and attention should be paid to the avoid ance of infection no less than to care of the disease itself. Rigid protection of houses by means of screens to keep out the Anopheles is one of the most important procedures. Further more, it is highly essential that the mosqui toes themselves should be protected from the infection by screening all patients suffering from malarial fever. In order to do this the pa tient's couch should be surrounded- y mosquito netting and all mosquitoes in the room of the malarial patient should be killed by means of pyrethrum-powder. Further measures for de stroying malaria should be taken by draining off swamps and employing proper engineering methods in order to get rid of the mosquitoes themselves. The planting of swamps with leafy trees often dries them up and thus pre vents the formation of breeding-places for mosquitoes. Finally the specific, quinine, should be used in all cases. It is a prompt and sure parasiticide and in its varied forms can he used by almost every patient, despite individual idiosyncrasies.
In the consideration of some of the chronic forms of the disease a number of perplexing conditions are met. Thus, following constant exposure to malaria and repeated attacks of the disease, symptoms of anemia, of breathless ness, swelling of the feet and ankles, bleeding in different parts of the body and enlarged spleen may be found. This is a type of infec tion known as malarial cachexia. It is found in southern countries and should be distinguished from the cache-Ida due to various forms of in testinal parasites.
