and somewhat, also, by the omission of certain chemical matters not 
deemed by the translator important to the American reader. 
The first part of this work treats in succession of the physical and 
chemical phenomena of vegetation, of the composition of vegetables 
and their immediate principles, of fermentation, and of soils. The 
second comprises a summary of all that has yet been done on the sub- 
ject of manures, organic and mineral: a discussion of the subject of 
rotations ; general views of the maintenance and economy of live stock ; 
finally, some considerations on meteorology and climate, and on the 
relations between organized beings and the atmosphere. Now that 
this valuable work is within the reach of all classes of readers and 
done into good English, we have no doubt that it will make its way to 
every remote hamlet in the land.
