Mr. Auguste Steitz exhibited a fine specimen of the last lower 

 molar tooth of the left side of Elephas primigenius^ found forty 

 feet below the surface, near the Missouri River and within one 

 mile of Helena^ Montana, in excavating for gold mining works, 

 lying above the gold-bearing quartz. He observed that many 

 teeth and tusks had been found, but the tusks crumbled as they 

 dried. Full skeletons doubtless existed in the same bed, but they 

 had not been dug up, because they crumbled to pieces. Another 

 tooth from the same locality had been presented to the Academy 

 on the 2 1 st of February last. 



Dr. Engelmann exhibited the fruit of Philodendron pertusum^ 

 from Mr. Shaw's Botanical Garden. It was the fruit of an aroid 

 climbing plant, with large palmate and perforated leaves. The 

 fruit was about ten or twelve inches long, and two and a half 

 inches in diameter, edible, and of a taste and odor which sug- 

 gested that of the pine-apple.
