No. II. Snppcfed to be an imperfecl Gypfeotn Jlonc of a blue

 made no experiments on tliis ; but it emits a fulphureous 

 fmell when heated in the fire.

No. 14.,^ Specimen of the calcareous cofjcret'wn, cemented 

 round pebbles and various other ftones, dug out of the bottom 



L 



of the fait fprings ; and found under the earth in large bodies, 

 along the declivity in the vicinity of the fprings. 0£ this na- 

 ture I take to be the rocky bottom of all the fait fprings of 

 Onondago, produced probably by a precipitation of the lime 



.from the water. (See my memoir on the fait fprings and man:- 



ufa(flories of Onondago. Agric. Tranf. N. Y. Soc. No. lIL 

 p. 99.) 





No. 15. A fample of the mojfy plant growing in abundance 

 in the bottom of the fait lake, wliich in fliallow places may 



r 



be feen almofl covering the whole of it. It ftill retains the 



peculiar fmell which feems to be imparted to it by the fait 

 water. ' I fijipedl it to be of the nature of the plant kali, and 



perhaps the mineral alkali might be obtained from it. 



No.
