In studying the effect of different electrolytes and cane sugar 

 on rheotaxis in Asellus, Allee (1, 2) finds that in many respects 

 the substances used affect the positiveness of the rheotactic 

 reaction in the same way that they affect many other physio- 

 logical processes. The antagonism between KC1 and CaCl 2 is 

 particularly well marked. The former increases and the latter 

 decreases the percentage of positive reactions and shows a 

 wholly similar effect on the rate of metabolism as measured by 

 resistance to the cyanides and production of C0 2 . The conclu- 

 sions are based on experiments on over a thousand individuals. 



Allen (3) gives some notes on the migrations, etc., of the 

 spiny lobster, Panulirus interruptus. 



In a study of the action of Schumann rays on living organ- 

 isms, Bovie (4) gives an account of the response of certain 

 amoebae and infusoria to this region of the spectrum. 



The Journal of Animal Behavior (5) publishes a translation 

 of Buddenbrock's " Die Tropismentheorie von Jacques Loeb" 

 (Biol. Cent., 35, 481-506). The original article was noted in 

 this review for last year. 



Attention is called to Cary's (6) study of the influence of 

 the marginal sense organs on the rate of regeneration in Cas- 

 siopea xamachana. A preliminary summary of this work was 

 given in this review for last year. 



Crozier (7) is of the opinion that the behavior of Holothuria 

 captiva when illuminated on two sides is such as to show " that 

 photic stimulation in this animal depends upon the amount of 

 light falling upon the sensitive surface, and is independent of 

 the angle of incidence." In working on Stichopus moebii he (8) 

 finds that the mechanism for the pulsation of the cloacal cham- 

 ber is locally contained, i.e., within the cloaca. He then takes 

 up a study of the. relation of certain chemicals, temperature,
