Nipher in the chair, and Messrs. Speck, Seddon, Wheeler, Tivy, 

 Engler, Adams, Leete, and Smith, present. 



The minutes of the last meeting were read approved. 



On motion of the Corresponding Secretary, the Technical So- 

 ciety of the Pacific coast was placed on the exchange list. 



The President appointed Messrs. Engler, Leete, and Seddon, 

 as a committee on programme for the ensuing year. 



Mr. Seddon made some very interesting remarks which were 

 suggested to his mind by the paper, read by Mr. Jewett at a pre- 

 vious meeting, on "The relations between the specific gravities 

 and the value of alloys of gold and silver." Mr. Seddon showed 

 by means of a chart how it was possible to indicate by means of 

 mathematical curves the relations existing between the specific 

 gravity and the value of alloys of any two metals, provided that 

 it were possible to determine the relations of the volumes of the 

 metals considered. As this latter relation, even in the simplest 

 cases, has never been determined, the results based upon any as- 

 sumed law must necessarily be inaccurate. 



Prof. Nipher exhibited and demonstrated the uses of Thomson's 

 Qtiadrant Electrometer.

 the importance of classifying them according to the construction 

 of their summit openings.
