 The river continues at its height until the beginning of May, and the 

 season terminates about the 20th June. The annual amount taken 

 by those seines and drift nets is calculated at about one million five 

 hundred thousand, worth, at the usual price, about one hundred 

 thousand dollars. The principal market is Philadelphia. — We 

 should like to see a scientific description of this fish with a little 

 more detail given to his habits during the ascent of the river. We 

 would recommend also the examination of the liquid contents of the 

 stomach, which is said to contain nothing solid, with a high magni- 

 fying power. Description of a new Trilobite, by Jacob Green,

 Account of an excursion to mount Katahdin, in Maine, by Profes- 

 sor J. W. Bailey, p. 20. The excursion seems to have been un- 

 dertaken rather hurriedly, and the time at the disposal of the party

 journey undertaken at leisure, and the members of the expedition 

 active and enterprising, rigidly examining the mountain and its en- 

 circling cypress swamps Remarks on the natural order Cycadese, 



with a description of the ovula and seeds of Cycas revoluta, Wild, 

 by A. J. Downing, p. 45. A lithographic figure accompanies the 

 paper. The remarks chiefly refer to the impregnation of the female 

 flowers, and the alliance of this family to the Coniferse.
