It can be contended that there is an individual susceptibilityin some cases, such as has been proved to exist in the case of flea-bites (Boycott)and those of mosquitoes and other insects. In other cases the phenomenon ofanaphylaxis probably plays a i^art, so that the susceptibility of the individual, asevidenced by the appearance of the lesions, is at first latent.
