 and differing from both, not only by the red spot being situated before the mid- 

 dle of the elytron, but by the abdomen being entirely black. 



On motion, it was resolved that a committee of five be appointed to 

 take measures for the formation of a permanent fund for the purposes of 

 the Academy, and that the plan adopted by them be reported to the 

 Academy for approval at the next meeting for business. 



March 1st. 

 Vice-President Bridges in the Chair. 



Fifty four members present. 



Dr. Robert E. Rogers exhibited Richie's modification of the Ruhm- 

 korff induction apparatus, and the modification of the ordinary electrical 

 machine, by Prof. Wagner, of Vienna; in the original machine a large 

 circle of wire carefully insulated is attached to the prime conductor ; 

 Dr. Rogers replaced this by hollow globes of glass silvered on the inside, 

 and showed that the power of the machine was thus greatly increased. 



On leave granted, the report of the Biological Department of the last 

 month was read and ordered to be printed. 



March 8lh. 



Dr. Hays in the Chair. 



Thirty-five members present. 



A specimen of Lepidosteus bison, taken at Bombay Hook, on the 

 Delaware River, was presented by Mr. Andrew Vanderslice.
