orifices. When this scent of new hay is vehement, it 

 becomes the flavour of bitter almonds." 



Both the fixed and volatile oils become concrete in 

 consequence of the absorption of oxygen, constituting 

 Wax in the former case and Resin in the latter. Wax 

 is found under various modifications, communicating a 

 glossy surface to many leaves, and existing in the form 

 of a yellow powder on the anthers of almost every 

 flower. From the latter, bees extract it, and though 

 at first yellowish and somewhat aromatic, it soon be- 

 comes white and inodorous, if exposed in thin layers 

 to the influence of the atmosphere and light. Wax as- 

 sumes various degrees of solidity, and different terms 

 have been employed to express the peculiar hardness. 

 Thus when obtained from the Chocolate Plant, Thco- 

 broma Cacaco, it is yellow and soft, forming the butter 

 of Cacao, and this is the substance from which the pe- 

 culiar flavour of Chocolate is derived. But when ob- 

 tained from the Bayberry, Myrica cerifera, it assumes a 

 more concrete form, and constitutes the well known 

 bayberry tallow, which, in this section of the country, 

 is frequently employed as a substitute for bees wax. 

 Wax is extremely inflammable, and exposed to a mod- 

 erate degree of heat, it is dissipated in the form of va- 

 pour. In consequence of its disengagement in thi^ 

 invisible shape, it sometimes forms a combustible atmos- 

 phere around the plant that yields it, and if in a dry seas- 

 on, a candle is brought near to the Fraxinella, its at- 

 mosphere is immediately inflamed, and the wax, which 

 is particularly abundant in that plant, furnishes a satis- 

 factory explanation of the phenomenon.

 It differs somewhat according to the peculiar tree from
