EXPERIMENTS ON THE SPLEEN. 103 



the produce of which from the above quantity of coal, ac- 

 cordinsj to Mr. Murdoch, would be about 600O ale gallons, 

 or 7000 wine gallons; as he has left it out of his estimate 

 from being or too trifling value. Neither have I taken into 

 account the expense for rents of houses, salaries, and wages, 

 with the other circumstances abovementioned, that must af- 

 fect the profits; though I have said enough to show, that 

 these, if any, must differ very widely indeed from the enor- 

 mous gains held out to the public, to induce incautious 

 individuals to embark in the project, when it was first set on ^ 



foot.

Farther Experiments on the Spleen. By Everahd Home, 

 Esq. F.R.S.* 



Ji HE results of the experiments already brought ixtr- Objectinview. 

 wardt having established the fact, that fluids received into 

 the stomach, when the pylorus is closed, pass through the 

 spleen into the circulation of the blood ; it became an object 

 to determine, by experiment, whether this takes place, when 

 the parts are in a natural state. 



The ass appeared, on many accounts, the best subject for The ass afa- 

 this purpose ; and as it ie made use of to teach the kcteri- yourable sub- 

 nary pupils the anatomy of that tribe of animals, I applied 

 to the Professor for permission to make my experiments in 

 the theatre of the college. 



This was granted me in the most obliging manner ; the 

 subjects were also supplied by the College, and Mr. Sewell, 

 the assistant Professor, gave me his personal aid with a de- 

 gree of zeal and ability I have rarely met with, and have 

 much pleasure in acknowledging.
