cake, but was made from dirty linseed, containing many small 

 weed-seeds, and 5 per cent of sand. 



6. Another sample of oil-cake, which had been sold at 13/. 10*'. 

 per ton, was sent for analysis by Mr. T. T. Porter, of Baunton, 

 Cirencester, and proved to be not a pure linseed-cake, but made 

 from dirty linseed, full of small weed-seeds, and starchy matter 

 which does not occur in pure linseed-cake. 



The following results were obtained on analysis : — 



Moisture 14-06 



Oil 10-41 



* Albuminous compounds 25-94 



Mucilage, starch, &c 29-07 



Woody fibre 13-4i» 



fMineral matter 7-03 



100-00 



*Containing nitrogen 4-15 



fContaining sand 3-11 



This cake, although sold at so high a price, was not invoiced 

 as pure linseed-cake. The Committee therefore withhold the 

 name of the vendor. 



7. A sample of soot, which was sent by a member who had 

 bought about 10,000 bushels of it, of a common sweep, at Qd. per 

 bushel, yielded on analysis the following results : — 



Moisture 2*11 



*Organic inatter 24-62 



Mineral matter 73-27 



100-00 



*Containing nitrogen -42 



Equal to ammonia -51 



Dr. Voelcker reported as follows : — " This sample contains 

 but little soot, and consists principally of ground coal-dust, ashes, 

 and rubbish, and is barely worth lOs. per ton. Good soot yields 

 from 3 to 4 per cent, of ammonia, and is worth about 2/. 2s. per 

 ton."
