The details of negative evidence and of lack of positive evidence need not be entered upon here, except in so far as to state that in the great majority of these cases the spider supposed to have inflicted the bite is not even seen, while in almost no case is the spider seen to inflict the bite; and it is a well-known fact that there are practically no spiders in our more northern States which are able to pierce the human skin, except

I went on to state that some of these insects are rather well known, as, for example, the blood-sucking cone-nose (Conorhinus sanguisugus) and the two-spotted corsairs
