after the fall of the leaves. The epidermis was found to bo 

 burst, and the periblem cells, greatly enlarged, protruded. 

 The speaker referred to previous studies of plant oedemas, 

 and compared the specimens here described, particularly, with 

 some oedematous apple twigs which had been made the sub- 

 ject of investigation at Cornell University. The latter were 

 observed in the early spring, before the expansion of the 

 leaves, but after the roots had been stimulated into premature 

 activity, and it was suggested that possibly the oedematous 

 willow roots might have similarly resulted from an unseason- 

 able root activity, while the plants were in a leafless condition. 



Professor J. H. Kinealy exhibited a simple glass model 

 very clearly illustrating the mode of action of the Pohle air- 

 lift pump, of which he had spoken at the last meeting.

A portrait of Dr. Enno Sander, which had been secured 

 through the efforts of friends of the Academy, was presented,

It sometimes happens that occasions arise in the history of our 

 Academy when our thoughts are directed back over our past record* 

 Sometimes these occasions tiave been full of sorrow, when some one of our 

 number has rested from his labors. To-night we seek to honor one of our 

 number who is still with us, and who still carries his full share of the 

 responsibilities of active membership. From the earliest year of its exist- 

 ence, forty-one years ago, he has been a worthy member of the Academy. 

 He was the associate of Engelmann, Eads, Shumard, Harris, Holmes, Riley, 

 and a host of worthy citizens of St. Louis, who are no longer here, and most 

 of whom have finished their labors. Dr. Enno Sander has been a most 

 important element in the life of the Academy. There have been times when 

 its future was anything but promising. It has passed through the turmoil 

 of civil war, it has suffered irreparable loss from fire, it has had seasons of 

 financial trouble which have put its affairs in serious straits. As Recording 

 Secretary, and continuously for the last thirty-five years as our Treasurer, 

 Dr. Sander has never failed us in any emergency. 



There has never been any self-seeking on the part of members of our
