Страница 73 - That portion of nitrogen existing as amids has been estimated in the alcoholic extract. The total nitrogen was also estimated and entered as albuminoids ; a small portion of the nitrogen has thus been counted twice in the total results which add up a little over 100.

This has been shown to be so widely true in the case of the plants hitherto investigated, that the generalization has been ventured on, that all the protoplasm throughout the plant is continuous. The formation of the dividing wall in cell division is now better understood than ever before, and our knowledge of this process lends great probability to the truth of the general statement made. It is not unlikely then...
Страница 75 - ... Cut the stalks about 1 inch above the ground, just before frost; after cutting, the stalks should be left to dry in a cool place a few weeks, and then placed in a trench and covered until time for planting. Some save the stalks by keeping them in a dry, cool place until February and then plant. The roots should be dug as used; they will not keep in good condition out of the ground more than three or four days.
