Abstract
INa recent paper read before the Royal Society,2 Prof. Marshall Ward described the results of three series of experimental cultures of Brome-seedlings in sand, to which had been added various nutritive salts, or manurial mixtures, which were then infected with the parasite to see how the latter behaved on starved seedlings. Some of the seedlings received all the salts necessary for successful development, others none of such salts other than the root-hairs could extract from the sand itself and from the reserves in the endosperm, and others all necessary minerals except phosphorus, or potassium, or magnesium, or calcium, or nitrogen respectively.
