*' P. S. Since the above was vi^ritten, I have, in consequence Sodaft-pm But^ 

 of your suggestion that the blood of Graminivorous animals {arge'qu^dLy. 

 might perhaps yield potash instead of soda, on account of their liv- 

 ing' exclusively upon vegetable food, examined bullock's blood, 

 ■with a view to ascertain this circumstance ; and as there was 

 noditficulty in procuring any quantity of that blood, I had some 

 gallons evaporated, from which I procured some ounces of salts, 

 in order to satisfy those who think that nothing certain can be 

 inferred from experiments upon a small scale. However, the 

 results were precisely similar, except that the crystals of sulphat 

 and nitrat of soda, obtained by the proc- sses above detailed, 

 were of much larger dimensions than in any of my former 

 experiments."

On the Culture and Preparations of Hemp in Dorsetshire, and 

 on the Growth of Sea Cale : by H. B. Way, Esq.* 



Dear Sir, 



AS you informed me, when you were lately in Dorsetshire, Informatlou 

 that the Society of Arts, &c. were anxious to obtain in- f'espectinf: 

 formation concerning the culture and preparation of hen)p in rable. 

 this neigbbourhoodj I am induced to send you some account 

 thereof. 



I fear my memorandums on the subject will not be worthy 

 the notice of the society, and I should scarcely have ventured 

 to have put pen to paper upon it, if I had not uniformly found 

 that the persons who are concerned in the growth and tna- 

 nagement of that article are shy of giving information. If 

 what I have sent should induce persons equal to the task, ^^ ^^^^^ n^riji^ 

 to make the needful inquiries in this county, Somerset, Suffolk, of England
