body. This inteftine motion, caufing a 

 continual friction betwixt the falts, oils, 

 water, and earthy particles of the plant, 

 mull comminute them, and raife a great 

 degree of heat. The oily particles undergo 

 a change from this heat, and acquire a 

 foetor j and, being joined by the air coming 

 from the putrefied mafs, become more 

 volatile, and affecT: the fenfe of fmelling. 

 The inteftine motion, it is eaiy to perceive, 

 muft take away all cohefion in the fibres 

 and particles j and fo they fall into a pulpy 

 fubftance. The oils and falts having a 

 natural affinity, will unite j and fo the falts, 

 by the natural volatility of the oil, will 

 become volatile themfelves, from being 

 fixed before. 



THIS is a very plaufible theory, though, 

 I muft own, liable to many objections. 

 The heat and weight of the atmofphere, 

 muft reach bodies preferved by the means 

 of oil, as well as if they were not rubbed 

 with it. We do not find thofe vegetables
