The poiaon gland, duct, and fang of Neme- sia cementaria. (After Blanchard.) fangs deeper into the flesh, during a period of many seconds, and at last quitted its hold volunta- rily, when a little blood issued from the wound. Though the spider was in a state of great excitement from pre- vious irritation, Mr. Blackwall did not experience more inconvenience from its bite than from a puncture made near it at the same time with a fine needle. The ef- fects of both injuries appeared to be very similar. Again, a highly exasperated female Diademata was allowed to seize him on the inner side of the left fore arm near the carpus. It continued for more than a minute to bury its fangs deeper into the flesh, Eflrect of g^j^j^ qjj quitting voluntarily, a little blood flowed from the wound- gP ed part, near M'hich a puncture was made simultaneously with a fine needle. The effects of this and the preceding experiment were alike. In both cases the air was sultry and the temperature as high as seventy-five degrees. These two wounds were inflicted in the month of July. In the latter part of August, a powerful and much irritated female Epeira quadrata bit Mr. Blackwall on the inner side of the left fore arm near the carpus. It retained its hold for the space of five minutes, occasionally forc- ing its fangs deeper into the flesh, and, on quit- ting it voluntarily, blood issued freely from the punctures. The effects of this bite did not dif- fer materially from those of a wound made at the same time with a needle of average size, the intensity and duration of pain being very similar in both instances. During the same month spiders of various species were induced, under the influence of ex- cited feelings, to seize a piece of clean window and the opening in the fangs through glass with their faugs, wlieu a tra
