Excerpt from The Mechanics of the Earth's Atmosphere: A Collection of TranslationsWith the exception ofos. F. Clarke's well-known paper, to which frequent reference will be made, practically no work has been done upon the development of the American alligator. This is probably due to the great difficulties experienced in obtaining the necessary embryological material. Clarke, some twenty years ago, made three trips to the swamps of Florida in quest of the desired material. The writer has also spent parts of three summers in the southern swamps - once in the Everglades, once among the smaller swamps and lakes of central Florida, and once in the Okefenokee Swamp. For the first of these expeditions he is indebted to the Elizabeth Thompson Science Fund, but for the more successful trip, when most of the material for this work was collected, he is indebted to the Smithsonian Institution, from which a liberal grant of money to defray the expenses Of the expedition was received.The writer also desires to express his appreciation of the numerous courtesies that he has received from Dr. Samuel F. Clarke, especially for the loan of several excellent series of sections, from which a number of the earlier stages were drawn.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
