l894-J LANEY — OUR TREES. 297 



It is a well known fact that Volvox, and, for that matter, all the 

 motile chlorophyl-producing forms of either animal or vegetable 

 microscopic life, are powerfully attracted by the light, either solar or 

 artificial. "And no wonder (you say) because without the aid of 

 sunlight the creature could not produce chlorophyl," and frequently 

 one will find that in these chlorophyl-bearing motile forms the red or 

 perhaps black eye-spot is present. To my mind this is sufficient evi- 

 dence to prove that the red eye-spot is an organ of vision, capable of 

 making its possessor sensible of the direction from which light pro- 

 ceeds. 



In the beginning of the present decade Professor Balbiani, in a 

 lecture before the College de France, announced his discovery of a 

 true crystalline lens in the eye-spot of Pandorina moriim, a form well 

 known as being a relative of Volvox globator. 



The paper was illustrated by large water colored paintings and 

 by living specimens of Volvox under microscopes. 



Remarks were made by Mr. Rafter in explanation and justifica- 

 tion of the statements in the paper criticized by Mr. Dumond. 



Mr. Dumond stated in reply that the paper referred to did not 

 correctly state the conclusions of the Microscopical Section. 



The next paper was entitled : 



OUR TREES. 

 By C. C. Laney. 



This paper gave a description of the cultivated trees, chiefly in 

 the grounds along East Avenue, in Rochester. In illustration Mr. 

 Laney exhibited leafy branches and flowers from a large number of 

 the rare and interesting trees to which he had referred. This paper 

 is published in full in the Democrat and Chronicle of Wednesday, 

 June 27th. 



Remarks upon the paper were made by Miss M. E. Macauley, 

 Mr. John Walton and Mr. G. T. Fish. 



The third paper read was : 



THE FLORA OF LONG POND. 

 By Anna H. Searing. 



The flora under consideration is for the most part found upon the 

 sand-bar, between Lake Ontario and Long Pond, which is one of a 

 series extending from Braddock's Bay to Charlotte.
