Inno case was the bite more severe than a pin prick and though in somecases the sensation seemed to last longer, it was probably due to thefact that the mind was intent upon the experiment. Similar experiments were carried out by Blackwell (1855), whobelieved that in the case of insects bitten, death did not result any. 6. An American tarantula (Eurypelma hentzii). Natural size. After Comstock more promptly than it would have from a purely mechanical injury ofequal extent. He was inclined to regard all accounts of seriousinjury to man as baseless. The question cannot be so summarilydismissed, and we shall now consider some of the groups which havebeen more explicitly implicated.

The famoustarantulas of southern Europe, whose bites were supposed to cause thedancing mania, were Lycosidce, or wolf-spiders. Though variousspecies of this group were doubtless so designated, the one whichseems to have been most implicated was Lycosa tarantula (L.),(fig. 4). On the other hand, in this country, though there are manyLycosidee, the term tarantula has been applied to members of thesuperfamily Avicularoidea (fig. 6), including the bird-spiders.
