distinguishing first the separate parts of a plant, and then 

 the different sorts of vegetables, and keep to this ; for if the 

 seed is not exactly divided from the leaf, the stem from the 

 root, and so on to thfe rest; and if the tree is not distin- 

 guished from the shrub, and the seniiplant, and herbaceous 

 plant, from the cryptogamia; it must inevitably create con-s 

 fusion, as they differ so essentially in form and manner of 

 growing. It is also most desirable to give but one part at 

 a time explaining this with a print, that may make it under- 

 stood, or the most perspicuous writer, on so dark a subject^ 

 Restofdu will want elucidation. But this gentleman, (though he be- 

 worJc^ gan so well) has launched into sorne system, which he seems 



to hold out, I think, as some mathematical demonstration 

 in the vegetable world. . I regret that he has not divided it 

 from his physiological labours, as both might have profited 

 by this ^arrangement, I have however so much to apologize 

 for myself, that 1 am the last person, that should criticise 

 others.

endeavoured to impress on the hearers of my chemical lec- 

 tures, how great must be the influence of the elastic fluids, 

 that surround putrescent bodies, either in accelerating or re- 

 tarding this natural process. This also has determined me.
