i^ents. Dr. Darwin is yet mqre fupcefsful in explaining the 

 cheniical influences of foiis,, airs, water, temperature, and 

 light, on the growth of plants, than in the eftabiifhrnent of 

 bis new theory of their phyfiology. But in this chemical 

 part of his work, he is .content to repeat the principles and 

 opinions of others without prefuming to propofe any import- 

 ant new theory of his own. 



The rules for the pra6tice of the gardener and hufband- 

 man, which be deduces as the refults from both his che- 

 mical and his ph)fiological refearches, are partly difperfed 

 through the previous divilions of the work, and partly alTem- 

 bled together towards the clofe. They befpeak ingenuity and 

 good fenfe, but do not fuffieiently wear the air of a prafticaJ 

 acquaintance with farrting, combined with accurate fcience. 



Throughout the work are fcattered fonie curious difquifi- 

 tions on fubjefts allied, indeed, to the primary dcfign, but 

 not entering direftly and unavoidably into it. The whole 

 will be read with great pleafure by the admirers of Darwin's 

 fprmer writing^^.

This work explains, in nine books, i. The general nature 

 and hidory of chemical fcience : a. The nature, names, and 

 peculiar ufes of the implenients for chemical experiments: 

 3. The chemical properties and relations of thofe fimple and 

 abundant chemical fubdances, caloric, oxvgen, hydrogen, 

 and azot : 4. The hiftory of all the acidifiable bafes except 

 the metallic, and of their acid compounds : 5. The hiftory of 

 the earilxs and alkalies, and of ihcir neutral compounds with 

 acids: 6. The nature and relations of metallic fubdances: 

 7. The hiftory of bitumens and fome other fubUances too 

 complex and anomalous in their relations to be conveniently 

 introduced into any of the foregoing branches of the arrange- 

 ment : 8. The cliemical hiftorv of the compofuion of ani- 

 mal and vegetable fubdances: and, 9. The application of 

 chemical fcience to the phenomena <jf geology, and to the 

 functions of aniukU and vegetable life, Sec. Sevtral articles
