by solutions of copper and salt diluted a,^ much as 10 million times. The metallic 

 salt is not fixed equally in all parts of the cell. At first it is found only in the mem- 

 brane, afterwards in the nucleus and nucleolus, and at length in the protoplasm. 

 At the termination of the exjjeriment the metals were found in all parts of the cell.

The autumnal translocation of material in the hop plant, C. Fruwirth and 

 W. ZiKLsTORFF {Laiidir. Vers. Stat., 56 {1901), No. 1-2, pp. .9-26').— This is a report 

 on a study of the hop plant to determine the translocation of matter at the end of 

 the gnjwing season. The plants whit-li entered into the experiment were protected 

 against such external influences as might have caused a loss of sul)stance. The vines 

 of some of the plants were removed at the time of harvesting, while those of others 

 were left until October when the different parts were analyzed. From the results 

 obtained the authors draw the conclusion that the diminution of nitrogen and phos- 

 phoric acid in the leaves and vines of the hop plant in the fall may be interpreted 

 as a translocation of these substances from the leaves and vines to the remaining 

 parts iA the plants. 



On the nitrogenous products of seed and seedlings of white lupines, 

 N. J. Wassilieff (Lniidir. IV/n. Stat., 55 {1901), Xo. 1-?, pp. 45-77; Ann. Agron., 27 

 {1901), No. 2, pp. 81-90). — A study was made of seeds and seedlings of the white 

 lupine to test the hypothesis of Schulze that in the decomposition of albumen during 

 germination there are afforded certain products, notably amido acids and hexose 

 bases, by the decomposition of albuminoid bodies. A great portion of these products 

 are transformed for the utilization of the plant. This transformation gives rise to 

 asparagin and glutamin. A nmnlier of experiments were conducted in which the 

 white lupine was used, and i-omparisons made with the yellow and blue lupines in 

 which the nitrogen content of the seeds and seedlings was investigated at regular 

 periods. The author's experiments show that the hypothesis of Schulze accords with 

 his investigations. Asparagin is formed in the seedling to the exclusion of other
