These deposits onthe lips and nasal orifices produce a markedirritation of the parts and give rise to small vesicles such as one sees in herpes febrilis. . .Intermittent, remittent and pernicious fevers,as well as yellow fever, cholera morbus and thetoxemias from serpents and other poisonousanimals owe their toxicitv to an animal or.

Intermittent fever is aserious disease spread by and due to the pre-valence of mosquitoes; and these fevers dis-appear or decrease in severity in forest regionsthat, because of their altitude, discourage thedevelopment of insect pests, quite apart fromthe amount of decaying matter in the neighbor-hood. . Indians living in marshy districts,as a preventive of fever and ague, build smokyfires at night in front of their huts. This is anefficacious means of driving away mosquitoes
