NEWS AND NOTES. 



At the January session of the New Jersey State Microscopical Society, 

 Dr. Byron D. Halsted read a very interesting and instructive paper on " The 

 Movement of the Sap in Plants." The paper was followed by a fine series of 

 lantern slides. During the past year it occurred to Dr. Halsted to prepare a 

 list of questions concerning sap, any one of which might naturally occur to 

 the "average layman" if he chanced to give the subject a little consideration. 

 " What causes sap to rise in plants ? " " Is there more than one kind of sap ? " 

 " Where is the sap in winter ?" and a number of other questions of a like nature. 

 Answers were received from representatives of a considerable number of pro- 

 fessions and made rather interesting reading. Suffice it to say that the botanist 

 was led to believe that a paper on the subject would not be amiss. 



J. A. Kelsey, Secretary. 



Recent experiments for obtaining pure cultures of algae have shown that 

 Cyanophyceae grow rapidly and luxuriantly in a decoction of Zamia, with the 

 addition of peptone and sugar. 



The accompanying figure rep- 

 resents a device which may be 

 used as a suitable lamp for field 

 work, and also as a substitute for 

 the blast lamp in laboratories 

 where gas is not available. A 

 torch designed to meet the same 

 purpose was figured and de- 

 scribed by W. J. Morse in Vol. 

 Ill, p. 986, of the Journal. 

 The " Queen " torch, manu- 

 factured by the Bridgport Brass 

 Co., has two burner tips ; one 

 for a round and one for a " fish- 

 tail " flame. There is an attachment for regulating the flow of gas, allowing 

 the flame to be turned down while not in use. This improved torch is recom- 

 mended by Prof Morse as one which satisfactorially serves all purposes for 

 which it was designed. 



THE QUEEN " TORCH. 



In Vol. IV, No. 1, p. 1129, the name of Prof. J. G. Adami was erroneously 

 given as Prof. Adann. In the same reference the first sentence of the third 

 paragraph should state that the pamphlet " How to Collect Mosquitoes " was 

 issued by the British Museum and sent to the Montreal Nat. Hist. Soc.
