Abstract
Proceedings of the Academy of Natwal Sciences of Philadelphia. Part 1, January to April.—Thomas Meehan, on disarticulating branches in Ampelopsis (the annual growth is disarticulated at just one node above that one made the previous year, the branch thus gaining but one node in the year. This reminds one of the South Pacific Vitis, which produces tubers on the end of the branches, and at the end of each season disarticulates them).—On germination in acorns (in Quercus virens. Mr. Mazyck has noticed that the two petioles instead of being short were produced to a length, of 11/2 inches before the plumule and hypocotyledonary portions of the young plant commenced their growth, and a small tuberous projection nearly one-fourth the size of the acorn preceded the growth downwards of the radicle and upwards of the plumule. The cells in all of these were gorged with starch).—Dr. Leidy, notice of Filaria immitis in the dog, and on a Filaria reported to have come from a man. —W. N. Lockington, on the Pacific species of Caulolatilus.— Heilprin, Angelo, on the stratigraphical evidence afforded by the tertiary fossils of the peninsula of Maryland.—J. S. Kingsley, carcinological notes: I. (chiefly relates to the genus Thelphusa, describes two new species from Ceylon and one from West Africa; also a new species of Dilocarcinus. II. Revision of the Gelasimi, plates 9 and 10).—Dr. Allen, description of a fœtal walrus, and on the mammæ of bats.—Dr. R. Bergh, on the nudibranchs of the North Pacific Ocean, with special reference to those of Alaska, Part 2, plates 1 to 8.—Howard Kelly, on a sartorius muscle in the gorilla. This muscle was reinforced six inches from its origin by a muscular slip a quarter of an inch in breadth; it arose at the lower part of the middle third of the femur, between the origin of the quadriceps extensor and the insertion of the adductors joining the sartorius opposite the knee joint.—J. II. Redfield, on Rochelia patens (Nuttell), decided by Dr. Gray to be Echinospermum floribundum.—Report on plants introduced by means of the International Exhibition 1876.
