Alpheus Spring Packard

thumb|Alpheus Spring Packard in 1888 Alpheus Spring Packard Jr. (February 19, 1839 – February 14, 1905) was an American physician, naturalist, textbook author, paleontologist, and zoologist, specializing in entomology. He was a professor of zoology and geology at Brown University from 1878 to 1905, served on the United States Entomological Commission from 1877 to 1882, and was the chief editor for the journal The American Naturalist from 1881 to 1905. He was elected in 1872 to the U.S. National Academy of Sciences and in 1878 to the American Philosophical Society. Quotes Morphology.—In order to properly understand Zoology, one should first study Morphology—i.e., the general structure of animals. The student should first thoroughly acquaint himself with the anatomy of a Vertebrate vertebrate animal, such as a frog, as compared with that of a toad or salamander. The examination and comparison of the Organ (biology) organs of animals belonging to distinct groups, is called Comparative anatomy Comparative Anatomy. The study of Morphology also includes the relation of the different organs to one another, and of all to the walls of the body. Finally, we need also to study the composition of the tissues of the different organs; each kind of Tissue (biology) tissue being formed of different kinds of elements or Cell (biology) cells. This department of Comparative Anatomy is called Histology (Greek, ἱστός, web or tissue; λόγος, discourse). It treats of the cell, and the combination of cells into Germ layer germ-layers, tissues, and organs.

The number of insects found upon some kinds of forest trees is astonishing, though it is to be remembered that all kinds are not equally destructive, the most injurious and deadly forms being comparatively few.Kaltenbach enumerates 537 species of insects injurious to the oak, and 107 obnoxious to the elm. The poplars afford a livelihood to 264 kinds of insects; the willows yield food to 396 species; the birches harbor 270 species; the alder, 119; the beech 154; the Hazel hazelnut, 97, and the hornbeam, 88.

The only scientific explorer of the interior is Henry Youle Hind Professor Hind, who ascended the Moisie River river Moisie, which, however, is a confluent of the St. Lawrence River St. Lawrence, and is in fact, situated only near the borders of Labrador, in the Quebe c province of Quebec. None of the larger rivers of Labrador have been explored to near their sources; and no one except Indigenous peoples in Canada Indians and but a single employee of the Hudson Bay Company (John McLean (explorer) Mr.McLean) has ever crossed any considerable portion of the interior.
