1894. | NEW YORK ACADEMY OF SCIENCES. 65 
The Secretary presented from the Council the following nomi- 
nations : 
Prof. CHariEs L. Brisront, Resident Member. 
Prof. M. ALLEN Starr, Resident Member. 
On motion they were elected. The Secretary announced the 
appointment by the Council of the following committee to have 
in charge the annual reception: Prof. Wm. Hallock, chairman ; 
Messrs. C. F. Cox, F. 8. Lee, Bashford Dean and Frank M. 
Chapman. 
Mr. Chapman subsequently resigned and was replaced by Dr. 
J. L. Wortman. 
Prof. D. 8. Martin presented the postponed report of the com- 
mittee on Standard Sizes, etc., and on motion it was referred to 
the Biological and Geological Sections. 
The Section of Astronomy and Physics then organized, Presi- 
dent Rees continuing in the chair. 
The first paper was by F. B. Crocker, ‘‘ On the Causes of Fly 
Wheel Accidents in Electric Stations.” Prof. Crocker outlined 
the methods for calculating fly-wheel sizes and stresses, and gave 
the result of some experiments with lead wheels, which clearly 
showed bulging where the greatest stress existed. He also tried 
a lead wheel on an electric motor, to show the method of obser- 
vation. The paper was discussed by a number of those present. 
The second paper was by H. C. Parker, “On the present 
Range and Accuracy in the Measurement of Electrical Resist- 
ance.” Mr. Parker outlined the methods of measuring high and 
low resistances, and showed that the range was from one ten mil- 
lionth of an ohm to ten million million ohms, or from 10-7 to 
10'3 ohms, a range of 102°. He also gave several illustrations 
of the meaning of this range. The paper was generally dis- 
cussed. 
On motion the meeting adjourned.
