ARBEITEN DES BOTANISCHEN INSTITUTS IN WÜRZBURG, heraus- 
gegeben von Professor Dr. Sachs. Erster Band. This volume of con- 
tributions from the Botanical Institute at Würzburg comprises four 
parts, which have appeared at nearly regular intervals since 1871. ° 
work can therefore be ranked among periodicals. In the present notice 
we shall give very briefly a sketch of the memoirs, hoping to present 
fuller outlines of several of them in subsequent numbers of the NAT- 
URALIST. 1. Dr. W. Pfeffer, On the Action of Colored Light on the De- 
composition of Carbonic Acid in Plants. (By an improved method of re- 
search the following results were reached: Only the visible rays of the 
spectrum can decompose carbonic acid ; in fact, those which seem bright- 
est, namely, the yellow rays, are alone as efficient in this work as all the 
others combined. ‘The most highly refrangible rays of the visible spec- 
trum, and those which act most energetically on chloride of silver, ete 
play a subordinate part in assimilation. Each color in the spectrum has 
a definite quantitative effect on the activity of assimilation.) 2. Dr. W.
