FOUNTAIN GUM BOTTLE. 



I have found that the fountain inkstand, sold for Stephens's ink 

 (but those sold by Mordan are probably as good), are the best 

 vessels to keep gum-water in for common daily use. The fluid part 

 of the gum-water being considerably above the level of the surface 

 of the gum which is exposed for use, prevents it from becoming dry, 

 as is so constantly the case in other kinds of vessels. — J. E. Gray. 



CARINARIA VITREA, LAMARCK. 



Three specimens of this very rare shell have lately been brought to 

 this country by Mr. Reeve, who purchased them at a sale in Holland. 

 The shell of the unhatched animal (as is shown by the shell re- 

 maining on the apex of one of the specimens) is smooth, polished, 

 nearly discoidal, and formed of several (three or four) slowly en- 

 larging whorls, so as exactly to resemble the shell of the Helix 

 lucida in form and appearance. When the animal is hatched, it 

 suddenly enlarges its shell, and changes its form. The keel is 

 formed of two distinct lamina?, one belonging to each side of the 

 shell. In both these particulars, which I believe have not been 

 noticed before, it exactly agrees with the more common Carinaria 

 Mediterranea. — J. E. Gray.
