Dionaea mnscipula, or Venus's fly-trap, grows sparingly in sauflj- soil near Wilmington, North Carolina, and in one or two other localities along the Carolina coast. Its leaf consists of two rather distinct parts, — the tvvo-valved trap at the extremity,. and a petiole-like support. It is probable that the support is not a true petiole, but a leaf-blade, while the trap is a special ap- pendage developed upon the tip of the leaf-blade. 895

The spting-trap is made up of two sj-mmetrical halves meeting at a median hinge. The outer border of each half is plate was divided into halves by a low wooden partition, one side teiug des- tined to be fed with meat, while the plants in the opposite half were to be starved. The plates were placed altogether under a gauze case, so that the 'starved' plants might be prevented from obtaining food by the capture of insects. The method of feeding consisted in supplying each leaf (on the fed sides of the six plates) with one or two small bits of roast meat, each weighing about one-fiftieth of a grain. This operation was repeated every few days from the beginning of July to the first days of September, when the final comparison of the two sets of plants was made " (Nature, xvii., 1878, p. 223).
