MINUTES OF THE INSTITUTE. 



August 4, 1910. — Regular monthly meeting, President 

 T. Chalkley Palmer in the chair. Reports of committees and 

 routine business. The insect called the "walking stick" was 

 shown as an example of protective mimicry. Dr. J. C. Star- 

 buck exhibited under the microscope Amceba dysenterica, of 

 especial interest in its apparent peculiar protoplasmic struct- 

 ure. T. Chalkley Palmer spoke of the so-called reticulated 

 structure of protoplasm. After further discussion, the opin- 

 ion was reached that the reticulated structure of protoplasm 

 could scarcely be disputed. Adjourned.

 President Henry L. Broomall in the chair. Reports of officers
