Verbal Communications. Mr. Clay remarked that on ex- 

 amining a series of magnesian minerals recently received by 

 him from Europe, he finds that four species which are describ- 

 ed as new, and perhaps a fifth, exist in the United States, 

 but do not appear to have been hitherto recognised by our 

 mineralogists. These species are Agalmatolite, Kerolite, Pic- 

 rosmine, Picrolite and Metaxite. (Breithaupt.) Mr. Clay thinks 

 that all these minerals (of which, however, he regards the 

 two last as doubtful species,) except Picrosmine, are found in 

 Chester and Delaware counties, Pennsylvania. Mr. Clay pro- 

 poses to investigate this subject more in detail. 



Dr. Blanding mentioned some facts in relation to the sur- 

 prising fecundity of the striped Bass, Labrax lineatus. He 

 obtained one of these fish which weighed 65 lbs. and the 

 roes 4 lb. 6 oz. 2 dr. He found one hundred of the eggs to 

 weigh a grain and a half; and although one end of the con- 

 taining membrane had been ruptured, whereby some hundreds 

 were lost, the whole number of eggs must have been at least 

 2,248,000. 



NEW BUSINESS. 



The committee appointed at a former meeting to wait on 

 Mr. Rembrandt Peale in reference to a portrait of the late 

 Mr. Thomas Say, ordered by the society, reported that the 

 same was now completed, and would shortly be suspended in 

 the Hall of the Academy.
