In every species of Cupuliferoe 

 which I have examined, whether 

 indigenous or exotic, great abun- 

 dance of crystals were found, 

 usually presenting the forms, fig. 

 6 to 9, but also having bunches 

 (form B, fig. 15) occasionally 

 mingled with them. In many

to see the crystals in situ, in 



thin layers of the liber. In the chestnut they may 



be seen thus in great abundance, and disposed in 



cells, as in fig. 3. 

 Cedrelace^e, Swietiana Mahagoni. In scrapings of Mahogany wood, 



and in the ashes, large crystals may be found in 



abundance. 

 Cornace^e, Cornus florida. Crystals abundant in the bark. 



Ericace^, 



Andromeda racemosa. Crystals small ; may be seen 



in ashes of leaf. 



Ebenaceje, 



Azalea viscosa. Crystals small. 



Diospyros Virginiana. Large and rather irregular crys- 

 tals, scattered through the leaves. 

 FRANKENiACEiE,Frankenia laevis. Bunches also. 

 Hamamelaceje, Hamamelis Virginica. Crystals abundant in ashes of 



leaf, along each vein, and easily isolated from the 

 bark.
