Page 308 - MUELLER.— THE ORGANIC CONSTITUENTS OF PLANTS AND VEGETABLE SUBSTANCES, and their Chemical Analysis. By Dr. GC Wittstein. Authorised Translation from the German Original, enlarged with numerous Additions, by Baron Ferd. von Mueller, KCMG, M.
Page 314 - It has been suggested that their siliceous elements were removed and replaced by carbonate of lime, but this appears to be most improbable. Professor Eoscoe and Professor Schorlemmer agree in stating that they would require overwhelming evidence before they would be prepared to accept such an explanation of the present condition of these objects or of the fact of the substitution of carbonate of lime for silica, that such an explanation renders necessary. Count Castracane has published an account...
Page 186 - Citations at second hand have been only sparingly used. The territory embraced includes Greenland and the Arctic Coast upon the north, and the borders of Mexico closely adjacent to the United States on the south, the habitat in the latter case being always indicated. For the flora of the region to the west of the Mississippi and northward, the citation of authorities is intended to be full and complete. The same maybe said (with some unimportant exceptions) for the Atlantic States prior to 1840,...
Page 318 - The raceme, after producing one ebracteate flower, produces at its second node a foliage-leaf, from whose axil the " usurping shoot" springs. By such an explanation we can dispense with any cumbrous adhesion-hypothesis such as that indicated above. The peculiarity is that the main axis does not per saltum pass from the condition of a leafy axis to that of an axis of inflorescence, but begins by producing one flower and then developing a foliage-leaf, beyond which the series of flowers is uninterrupted....
Page 314 - Koscoe kindly allowed one of his ablest assistants in his laboratory at Owens College to prepare analyses of a number of coals according to Count Castracane's method. The residual ashes of these preparations have been mounted microscopically by Professor Williamson, and in no one of them can a trace of a diatom be found. Beyond stating the fact, he is wholly unable to account for the discrepancy between his results and those of the Italian observer ; so far as his present observations go, he finds...
Page 317 - Payer) we do not know of connection of all three together. It is possible ; but, I think, improbable, The view which, after careful consideration, occurs to me as most fully satisfying the conditions of this remarkable case may be stated briefly in categorical form as follows : — 1. The racemose inflorescence is terminal, and properly begins just above the level of the " second last " leaf. It would thus include the aforesaid solitary flower. 2. The raceme after producing one ebracteate flower,...
Page 90 - ... but the breadth was less (6.74 to 7.33) ; a moist atmosphere is more favorable to length of leaf-sheath in the proportion of 9.26 to 8.18, to growth of the principal stem (13.5 to 11.5) and to root development (26.8 to 23.9). It was found that the epidermal cells of the leaves were more numerous and broader, the cells between the stomates shorter, and the stomates themselves shorter in dry air. Also, that leaves developing in a moist atmosphere have comparatively fewer stomates per millemetre...
Page 317 - ... indeed, which offers a morphological problem of considerable difficulty, and which probably can be effectually solved only by developmental study. The peculiarity consists in the constant occurrence of a solitary flower springing somewhere from the internode below the raceme, either about half-way down towards, or almost close to, the level of the leaf below. So far as observed, the solitary flower is never quite so low as the level of the lower leaf.
Page 313 - Traquarice of Mr. Carruthers, found in the lower coal-measures of Lancashire and Yorkshire, with small spherical objects that observer believes to be Radiolarians like those still living in existing seas. Professor Williamson showed that the radiating projections with which these spheres are surrounded were not siliceous spines like those of the...
Page 7 - This nakedness is a universal characteristic of the mountain scenery in China, but it is not the fault of the soil or the climate, for wherever the little pines are allowed to rise they show a vigorous growth.
