Indian rape was present among the impurities, but not to a 

 very large extent. There were, however, several other small 

 seeds resembling it, and also a few somewhat like the lentil, 

 though certainly not identical with that seed. The seed con- 

 tained — - 



The impurities in this sample being so abundant as to admit 

 of their being separated in large quantity, an analysis of them 

 was made with the following results ; and as the seed contained 

 so much oil that it might be pressed, I have added the calcu- 

 lated composition of the cake it ought to yield. 



Water, 



Oil, 



Albuminous Compounds, 



Mucilage, Gum, &c, 



Fibre, 



Ash, 



Nitrogen, 



The Ash contains — 

 Phosphates, 

 Phosphoric Acid, combined 



with Alkalies, 

 Sand, .... 



Bomlay Linseed. — Two samples have been analysed, both of 

 excellent quality, the seeds being large, well developed, and 

 polished on the surface. They were very pure, the percentage 

 of foreign seeds being 3-94 in the one, and 5-32 in the other. 

 The results of analysis of the first sample, containing 3-94 of 

 impurity, were —
