Excerpt from The American Naturalist, 1906, Vol. 40: An Illustrated Magazine of Natural History It is so rapid that it is not easily recognized at any great distance until experience has sharpened the eye. Therein lies, I think, the cause of the birth Of the aeroplane theory, though I must add that experience need not necessarily sharpen even good natural sight into being able to see the wing-movement. Knack or chance may come in in such matters. Some time ago, for instance, I was astonished, whilst testing the shooting of a shot-and-ball gun at the butts, to find that in certain lights I could plainly see the ball during its whole flight, whilst the attendant whose daily busi ness it was to test rifles and guns, and whose sight was far supe rior to mine, tried over and over again but could not pick it up. So have I seen many watch the whirring wings and declare them to be still. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book Description
Excerpt from The American Naturalist, 1908, Vol. 42: A Monthly Journal Devoted to the Advancement of the Biological Sciences, With Special References to the Factors of Evolution There is some indication that the delay in the forma tion of the new leg in the frog is due to conditions exist ing in the bones or muscles and, as I have pointed out,1 it is significant to find that in the vertebrates the loss of power to regenerate a limb appears where cartilage has been changed to bone. The result is not however due directly to the ossification, since the new material is derived from the periosteum and not from differentiated tissue.
