Article VII. 



On the Action of Lime upon Animal and Vegetable Substances. 



By Mrs. Ibbetson. 



SIR, Exmouth, Dec. 9, 1818. 



I return once more to my trench. I have, after three 

 months' trial, again examined the plants that were placed in it ; 

 and though many have died in consequence of the extreme heat 

 and want of moisture of this uncommonly fine season, yet most 

 of those which are indigenous have thrown up shoots. Thus, 

 confirming the former results, and again proving the folly of 

 digging up weeds and then burying them to make manure, 

 which was not produced in my first experiment, by even a three 

 years' trial, though they were covered all that time with earth, 

 and placed in the most favourable manner to produce it, if 

 manure from decayed weeds could so hastily be procured by this 

 means. 



I now proceed to the next experiment, which indeed has fur- 

 nished a result so singular and unexpected, that I have not yet 

 got the better of my surprise. I mentioned in my first letter my 

 intention of examining the truth of those generally received
