Book excerpt: Excerpt from The American Naturalist, 1909, Vol. 43 After the plant has reached about a decimeter in length the basal cone ceases to increase and later is lost in the growth of the stipe (fig. At the same time the disc begins to enlarge and spread out on the substratum, giv ing a firmer hold for the increasing lamina above. This enlargement is clearly in the region of the primitive disc and not in the conical basal swelling above, which remains part of the stipe. These two tendencies of growth work ing together usually cause the sharp distinction between the holdfast and stipe to reappear, and in plants more than 15 cm. Long the conical base is seldom prominent (fig. In adults the disc becomes very flat and thin by its continued extension (fig. Has. 7-11. Bentrewia.

Book excerpt: 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 excerpt: 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.

I had seen fledged young ones about the Eucalyptus trees several days earlier, so that they must hatch in many nests as early as March 1st. Three cold rains occurred during the development of the one I watched. During all the tituc of development both of eggs and young there have been white frosts at night and fresh, piercing cold winds dur ing the day. As with the Nootka Hummers the females perform the task of hatching and feeding the young entirely by themselves, the males dis appearing from the lowlands and gardens after the eggs are laid, and re tiring among the richer flowers of the mountain canons.
