JacksoiiTille, Fla., which constitute the public water supply: he 

 also exhibited specimens from the strata pierced in sinking the 

 wells, the deepest being 650 ft.; 17 different strata were pene- 

 trated, consisting of sand, shell conglomerate, blue clay, and very 

 hard sandstone. The water obtained is at first sulphurous in 

 taste and odor, the taste disappearing after a short exposure to 

 the air. The temperature of the water is about 75° Fahr., pres- 

 sui"e 26 lbs. 



Mr. Emory Smith made some remarks about Diomva niusci- 

 pitla (Venus Flytrap), stating that, according to his experiments, 

 the closing of the leaves was due to the motion of the insect, and 

 that if these motions had ceased the leaves would open again, so 

 that the insect would drojD oft' or be blown away, but not absorbed, 

 by the plant. 



Prof. Trelease remarked that the observations reported were 

 very interesting, but would bear repetition with a view to deter- 

 mining the local causes to which the results obtained were attri- 

 buted, as his own limited experiments on the Venus Flytrap wer^e 

 corroborative of the results obtained by Darwin and other eminent 

 biologists, showing the plant to be truly insectivorous.
