Sir, 



For the particular inspection of the president :,nd the 

 officers of the society, and for the view of those mem- 

 bers who may think the matter interesting, I have given 

 a rough sketch of my land, which although not done 

 with mathematical accuracy (not having used my scale 

 and dividers), will shew the operation oi the disease as far 

 as it has yet appeared* The vice president knows well 

 the situation of my land, being in the practice of pass- 

 ing it, at least semi-annually, and will see that the sketch 

 is nearly correct. 



Yours very respectfully. 



James Parker. 

 Dr. James Mease.
