Br Davy's Agricultural Discourse, 359 



Norton, your pupil, who is here engaged with this analysis, has, 

 for instance, prepared legumin from green peas (which differs from 

 that of almonds), and obtained the following result, — 



100- 94-8 100- 



Legumin from peas, therefore, contains the same substance as that 

 which exists in fibrin and horn, combined with sulphuret and 

 phosphurut of amid. This is confirmed by all its reactions. 



I will here add nothing more, but I think I have shewn, that a 

 little more order is appearing in this chaos, and that it is far more 

 useful to science, to distinguish between sulphur and sulphur, than 

 to allow such a distinction to escape us. 



Believe me, 



Yours faithfully,

A Discourse delivered before the General Agricultural Society 

 of Barbadoes, at its Second Half -Yearly Meeting on 22d 

 of December 1846. By John Davy, M.D., F.R.S., Inspec-

 Society, &c. Published at the request of the Society, and

 Journal. 



Gentlemen, — At your last, which was also your first, meeting, 

 I had the honour of addressing you on the subject of agriculture ge- 

 nerally, considered in some of its scientific relations. I now propose 

 to endeavour to perform the promise I then made, and, with your 

 leave, call your attention to the soils of Barbadoes, which, as the 

 basis of your agriculture, cannot be too carefully studied, cannot be 

 too thoroughly known ; and such thorough knowledge, I need hardly 

 remark, can be acquired only by minute and accurate examination. 



I shall first speak of the soils of the island generally, so far as I 

 have yet had an opportunity of observing them ; secondly, of the
