Posteriorly the dilated part becomes stronger in texture, insensibly con- tracts (g), then undergoes a second dilatation (A) before it opens into the rectum (*'). It is near the latter part, in a kind of pouch, that the slender vessels open which M. Treviranus calls biliary vessels, and which he is, with reason, surprised to see terminating in so extraordinary a position. These vessels, in fact, which cha- racterize so well by their presence the chilific stomach of insects, and are situated in these animals more or less anteriorly, always pre- ceding the small intestines which have a greater or less length, terminate in the spiders in the rectum itself, and close to the Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Todd, Robert Bentley, 1809-1860.
