Book Description
Excerpt from Smithsonian Miscellaneous Collections, 1905, Vol. 48: Quarterly Issue I have taken no notice of the numerous new terms concerning the arrangement of the feathers proposed by Alix (1864, p. Wray (1887, pp. 344 - 345) and others, the older divisions into hand remiges and arm - remiges being quite sufficient for my purpose. It was to be foreseen that the treatment of such brittle and hard material as the horny substance of feathers would present serious technical difficulties. Former investigators have left no record of the way in which their examinations on developed feathers were conducted. It is true that Strong (1902, pp. 148 - 1 51) has described his mode of procedure rather fully, but he speaks merely of the treatment of feather germs. I treated the material to be examined in the following manner: I took one of the three outermost hand - remiges, usually the longest, and one of the arm-remiges of each Species of bird to be examined, and placed a portion of the vane on the Slide mounted in balsam.

Excerpt from Smithsonian Miscellaneous Collections, Vol. 47: Quarterly Issue, Volume II F esting. Moreover, the evidence for the water vapor bands (includ ing that at p), given in plate 1, figure I, and plates Iv and V, should be conclusive of their origin. This does not necessarily mean that the particular nicks in the curves are atmospheric; they may be due to some solar line superposed on the greater atmospheric band. By far the greater portion of the absorption must, however, be terrestrial. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
