Seite 301 - The power of procuring intermediate varieties by the intermixture of the pollen and stigma of two different parents is, however, that which most deserves consideration. We all know that hybrid plants are constantly produced in every garden, and that improvements of the most remarkable kind are yearly occurring in consequence.
Seite 51 - ... to which the valve has been adjusted, but is superior to it, by which it is enabled to overpower the resistance of the weight t, and it carries the valve up with it, and closes the orifice r. This is no sooner done, than the water is constrained to become stationary again, by which the momentum is...
