Wohlfartia magnifica is anotherSarcophagid which commonly infestsman in the regions where it is abun-dant. It is found in all Europe but isespecially common in Russia, wherePortschinsky has devoted much atten-tion to its ravages. It deposits livinglarvae in wounds, the nasal fossae, the ears and the eyes, causing injuries ^- c^hrysomyia maceiiaria.

We come now to the more modern aspectof our subject,—the consideration of insects and other arthropodsas transmitters and disseminators of disease. The simplest way in which arthropods may function in thiscapacity is as simple carriers of pathogenic organisms. It is con-ceivable that any insect which has access to, and comes in contactwith such organisms and then passes to the food, or drink, or to thebody of man, may in a wholly accidental and incidental mannerconvey infection. That this occurs is abundantly proved by thework of recent years. We shall consider as typical the case againstthe house-fly, which has attracted so much attention, both popularand scientific.
