The tap root of the oak, about which so much has been written, will possibly be adduced as an exception; but having attentively examined at least 20,000 trees of this species, many of which had grown in some of the deepest and most favourable soils of England, and never having found a single tree possessing a tap root, I must be allowed to doubt...
Pagina 79 - In air and vapours this force appears to act uncontrolled ; but in liquids it is overcome by a cohesive force, while the particles still retain a power of moving freely in all directions It is simplest to suppose the force of cohesion nearly or perfectly constant in its magnitude, throughout the minute distance to which it extends, and owing its apparent diversity to the contrary action of the repulsive force which varies with the distance.

I could adduce many more facts...
Pagina 259 - ... a sieve. The feathers should be afterwards well washed in clean water, and dried upon nets, the meshes of which may be about the fineness of cabbage-nets. The feathers must be from time to time shaken upon the nets, and as they dry will fall through the meshes, and are to be collected for use.
