Quarterly Reports of the Chemical Committee. 255 
In conclusion, I have to report that for the last three years 
Mr. Charles L. Curtis, Deanjers-Farringdon, Alton, Hants, has 
kindly carried out, under my direction, some field-experiments 
on permanent pasture, and has favoured me with the results of 
the experiments, which perhaps may be of sufficient interest to 
warrant their publication in full in the ' Journal ' of the 
Society (see table, p. 254).

1. A SAMPLE of linseed-cake of a lot of 10 tons bought in 
October, by Mr. Wm. Holland, Market Deeping, at lOZ. lis. 3rf., 
on analysis yielded the following results : — 
Moisture 9 • 75 
Oil iri5 
* Albuminous compounds (flesh-forming matters) .. 23 "94 
Mucilage, starch, and digestible fibre 33 " 22 
Woody fibre (cellulose) 13*90 
fMineral matter (ash) 8*04 
100-00 
* Containing nitrogen 3-83 
t Including sand 3*35 
This analysis shows that the cake was rather deficient in albu- 
minous compounds, and contained 2)\ per cent, of sand. The
