Development of the Digestive Canal of the American Alligator
In the printed text, all illustrations were labeled with their scale, varying from 190 (highly magnified) to 1 (actual size). The exact size of images on a computer screen depends largely on your monitor type; settings can generally not be changed without affecting other aspects of the display. The scale shown here was used for all measured illustrations. It may appear slightly larger or smaller than intended. Most illustrations link to unscaled larger views. In the present paper the development of the enteron is described in detail, but the derivatives of the digestive tract (liver, pancreas, lungs, etc.) are mentioned only incidentally; the development of these latter structures may be described in a later paper. The material upon which this work was done is the same as that used for the preceding researches. It was collected by the author in central Florida and southern Georgia by means of a grant from the Smithsonian Institution, for which assistance acknowledgment is herewith gratefully made. Various methods of fixation were employed in preserving the material. In practically all cases the embryos were stained in toto with Borax Carmine and on the slide with Lyon's Blue. Transverse, sagittal, and horizontal sections were cut, their thickness varying from five to thirty microns, depending upon the size of the embryos. ......Buy Now (To Read More)
