Dr. Genth described some striking results of recent analysis 
of Pseudomorph Corundums, and promised a fuller account 
of them when his investigations were further advanced. 
Prof. Cresson desired a memorandum to be made of the 
appearance of the tender shoots of the swamp cabbage, blue 
bell and other wild flowers, under remarkable circumstances 
of difficulty, in a part of Belmont Glen, in the Philadelphia 
Park, where an artificial asphalt road had been laid directly
