2. Liquid Manure from Badminton. 



Mr. Thompson, agent to his Grace the Duke of Beaufort, 

 kindly supplied me with a specimen of liquid manure, which had 

 been kept for several years in the tank. It was much darker 

 coloured than the liquid from Westonbirt, and contained a larger 

 amount of organic matter in solution than any of the other 

 varieties of liquid manure which I examined. It was nearly 

 neutral to test-paper, but on boiling gave off a strong smell of 

 ammonia. Its smell was not so offensive as the liquid from 

 Westonbirt. 



The Badminton liquid was composed chiefly of the drainings 

 of cattle-sheds and yards. Its examination appeared to me de- 

 sirable for the sake of comparison with the preceding sample, 

 which was principally composed of horse-urine. 



On evaporation to dryness on the waterbath, 7000 grains fur- 

 nished 60-112 grains of solid residue dried at 212 Fahr. This 

 quantity on burning gave 36'190 grains of mineral matter or ash. 



On analysing the ash it was found to contain in 100 parts of
