Seite 481 - Dunstan saw to his horror that its body was bloodstained, while the skin appeared to be actually sucked or puckered in spots, and the animal staggered as if from exhaustion. In cutting the vine the twigs curled like living, sinuous fingers about Mr. Dunstan's hand, and it required no slight force to free the member from their clinging grasp, which left the flesh red and blistered.
Seite 245 - ... subsoils containing organic nitrogen, lower organisms may serve the higher plants by taking up or attacking and bringing into a more readily available condition combined nitrogen not otherwise, or only very slowly, available for the higher plants. For example, it is probable that fungi generally derive nitrogen from organic nitrogen ; and in the case of those of fairy rings there can be little doubt that they take up from the soil organic nitrogen which is not available to the meadow plants,...
Seite 120 - Europe, did not their high price, varying from two to 150 dollars, prevent their importation. They are distinguished from all others by consisting only of a single piece, and by their lightness and flexibility. They may be rolled up and put into the pocket without injury.

Seite 246 - SUMMARY AND CONCLUSION. There is no evidence that the leguminous plant itself assimilates free nitrogen. The evidence at present at command, is in favour of the supposition that the observed gain is due to the fixation of nitrogen in the development of the lower organisms in the root-nodules, and that the nitrogenous compounds produced are taken up and utilised by the leguminous plant.
