 The retiring President, Mr. J. D. Hyatt, delivered the Annual 

 Address, entitled "Hints of Intelligence in the Movements of 

 Plants." The address was discussed by Messrs. C. Van Brunt, 

 W. J. Lloyd, Rev. G. E. F. Haas, and Drs. Carl Heitzmann and 

 N. L. Britton. 



Dr. Carl Heitzmann exhibited a photomicrograph of the 

 endosperm of the Ivory Nut, and remarked upon it as follows : 



" It is a curious coincidence that, while the President dwells 

 on the puzzle of the movements of plants, I hold the solution 

 of the puzzle in my hand. It is a photomicrograph made by 

 Mr. Maximilian Toch. The object is a section through the 

 ivory nut, or vegetable ivory, prepared by a method peculiar to 

 Mr. Toch, and to be published by him in due time. 



" In an address last May I showed in this Society a photo- 

 micrograph by S. Strieker, of Vienna, illustrating the reticular 

 structure of living protoplasm, discovered by myself twenty years 

 ago, and now accepted even by French histologists, as proven 

 by a letter published by Dr. Alfred C. Stokes in the last number 

 of Science. What the French term ' hyaloplasma ' I have de- 

 signated as the living or contractile matter, and their * paraplasma ' 

 with me is a lifeless liquid filling the meshes of the reticulum. 

 The same features, in a meeting of last October, I demonstrated 

 to be present in the protoplasm of plants, and I showed the 

 delicate, thread-like connections piercing the cement or cellulose, 

 which I have claimed to be formations of living matter, uniting 

 the reticulum in the protoplasm of our so-called ' cell ' with that 

 of all neighbors, thus rendering the plant an uninterrupted con-
