Mr. Sprague stated tliat the Nasturtium sylvestre of Europe, 

 which has been naturalized in the neighborhood of Philadelphia, 

 is now naturalized on the banks of Charles river, in Newton 

 meadows. 



Dr. B. S. Shaw stated that he had noticed frequently during 

 the past summer, after rains, the appearance of earth-worms in 

 a reservoir in the yard in rear of his house. This reservoir was 

 three feet long, one and a half wide, and one and a half high, 

 without cover, of wood, painted, and its sides were quite perpen- 

 dicular. The yard was paved with brick, and the reservoir 

 rested immediately upon the bricks, and was lined with lead. 

 It was used to contain tadpoles, snails, &c., and he had noticed 

 in it during and after a fall of rain, from one to twenty com- 

 mon earth-worms, of all sizes, and, generally, all alive. The 

 reservoir was repeatedly emptied of its contents, washed and 

 dried, and yet, after every rain, a greater or less number of 

 worms was seen in it. The reservoir being at the foot of a 

 trellis covered with grape vines, under the supposition that the 

 worms might have fallen from this, it was removed to the centre 

 of the yard, where nothing could fall into it from the walls of the 

 house, or the trellis, and yet the worms appeared as before. 

 They were seen about on the bricks at the same time, and, in 

 some instances, coming up between the bricks, but they were 

 never seen mounting the perpendicular and smooth sides of this 

 reservoir. 



Dr. Keep stated that he had found earth-worms on bushes and 

 rough boards, several inches above ground, but in these cases 

 they could have reached these spots without mounting perpendi- 

 cularly. 



Dr. Durkee had seen them on slabs in the Granary burying- 

 ground, several inches above ground. He thought as they can 

 surround twigs, and move them on the ground, they may possi- 

 bly mount twigs spirally, where they can clasp them, but did 

 not understand how they could climb a smooth, perpendicular 

 surface. 



Dr. Burnett remarked that they move on horizontal surfaces.
