SECTION OF PHYSICS. 
_ The President, Dr. J. S. NEWBERRY, in the Chair. 
Sixty persons were present. 
An invitation was received to send a delegate to the third an- 
nual meeting of the RoyaL Society or CANaDA. 
Letters of resignation from Messrs. C. F. Imprir, W. Le ContE 
STEVENS and J. K. Funx were read and accepted, and Mr. Joun 
G. BRANNER, of Scranton, Penn., a geologist to the Pennsylvania 
Geological Survey, was elected a Corresponding Member. 
Mr. G. F. Kunz exhibited some very small crystals of quartz, 
found in the Bear River region, Idaho, and Fort Defiance, Arizona, 
where thousands of miners are looking for diamonds. These 
crystals of quartz resemble those of that mineral, from their 
rounded and, apparently, octahedral form, which is due partly to 
the mode of crystallization, the two sets of pyramidal planes of 
‘the terminations closely approaching each-other, and partly to 
abrasion by rolling in streams. 
The PResIDENT had found quartz crystals of the same form in 
the Shell Creek range, in Eastern Nevada, scattered in thousands 
through a trachytic rock, as well as in a similar rock of the Black 
Hills. He had examined the material washed from the sands of 
Upper California in search for platinum. In this a diamond of the 
weight of five-eighths of a karat had been found, and one even 
larger. 
A paper was then read by H. Carrincton Botton, Ph.D., of 
Trinity College, Hartford, illustrated by a series of specimens, 
on 
RECENT VISITS TO “SINGING BEACHES” IN SCOTLAND AND 
AMERICA, 
[ Abstract. ] 
The speaker stated that, since the paper by his co-worker, Dr. ALEXIS 
A. JULIEN, on the “ Singing Beach of Manchester, Mass.,” had been 
read before the Academy, he had continued his investigations, and
