Botanische Zeitung. Reinke’s paper on Investigation of Growth is 
continued in the numbers since our last notice, and down to No. 10, 
March 10th. The paper is of great interest, and will be noticed at 
some length in the June NATURALIST. 
ARBEITEN DES BOTANISCHEN INSTITUTS IN WÜRZBURG, herausgege- 
ben von Professor Dr. Julius Sachs. We resume our notice of this volume 
of Botanical Contributions from the Würzburg Laboratory with the third 
part, which begins with a paper by Dr. Hugo de Vries, On the Wilting 
of Cut Shoots. (De Vries has clearly pointed out the marked difference 
in effect between cutting shoots under water and severing them with 
exposure of the cut surface to the air. The former shoots wither far less 
than the latter.) IX. Hugo de Vries, On Growth in Length of Tendrils 
which curve on the Upper or the Lower Side. (The effect of irritation 
to change the rapidity of growth is not local, but is felt in certain cases 
throughout the tendril. The effect is often continued after the removal 
of the irritant or the body in contact.) X. Hugo de Vries, On the 
Mechanics of Living Plants. (Abstract given in Sachs’ Text-Book, page 
777.) Dr. Emil Godlewski, Dependence of the Elimination of À 
777 
Oxygen from Leaves on the Amount of Carbonic Acid in the Air. (l 
Increase in the amount of CO, in the air up to a certain limit favors the 
evolution of oxygen; above this limit it is more or less injurious. 2. This 
limit varies for different plants: for Glyceria spectabilis on clear days, 
between eight and ten per cent.; for Typha latifolia, between five and 
seven per cent.; for oleander a little lower. . . . 5. Increase in intensity 
of the light increases the evolution of oxygen.) XII. Dr. K. Prantl, 
On the Influence of Light on the Growth of Leaves. (Attributing the 
difference between growth in light and growth in darkness to the patho- 
logical condition induced by absence of light.) XIII. and XIX. Pro» 
fessor Sachs, On the Growth of Tap and Side Roots. (An interesting 
and elaborate memoir, to be hereafter given in abstract in our General 
Notes.) XIV. Dr. Hermann Müller (Thurgau), On the Protonema and 
Rhizoids (root-hairs) of Mosses. XV. Dr. Oscar Brefeld, On Alcoholic 
Fermentation. XVI. Dr. Hugo de Vries, On the Extensibility of Grow- 
ing Shoots. XVII. Dr. K. Prantl, On the Renewal of the Growing P oint 
in the Roots of Angiosperms. XVIII. Dr. R. Pedersen, Have 1 
tions in Temperature, as such, an Unfavorable Influence on Growth!

In closing this sketch of the first volume of Contributions from the’ : 
Wiirzburg Laboratory, we must be allowed to call attention to an 1m- 
portant and excellent feature of the publication, namely, the summary 3t
