234 Memoir on the JFool aiid Sheep 



" Nf)\v, since pipes of different natures draw off different 

 fluids from one and the same heterogeneous fluid, it fol- 

 low;!, tl\al the secerning pipes of the glands, according to 

 then- diitevcnt natures and dispositions, suck ia various 

 iuices from the blood, which is a heterogeneous fluid con- 

 sisting of a great variety of parts : and, consequently, the 

 proposition is true." 



This work, which contains 338 pages, shows how 

 much the knowledge of the animal oecononiy was advanced 

 in those days, and how great a genius Sir Isaac Ncwtou 

 was, and the jirevalencv ot his opinions, now almost passed 

 by in ohhvion. And in a second letter, for this, I fear, has 

 ah.-eadv bccoine too long, which I shall have the honour to 

 address to you, 1 shall endeavour to show that the new che- 

 mical doctrines, as they are commonly called, were the 

 doctrines of IIo(jk, who was contemporary with Sir Isaac 

 Newton, and published prior to Mayow by \\\m : and if in 

 following up your plan I shall cast out any additional lights 

 on so intcrestit\g a subjecl as you proposed, I shall tei^ 

 highlv gratified ; and have the honour to remain, dear sir. 

 With all due respect and esteem. 



Your faithful obedient servant, 



IloBEUT John Thornton.

 is suliicRmt merely to mention it. It is an axiom of poli-

 breeding sheep is, I w ill venture to say, one of the most 

 ridvan!:i'.?:eous : it retpiires constant attention on the part of 

 the proprietors ; it culls for the meditation of agriculturists 

 and tlie solicitude of government. 'I'his branch, so inte-
