DEAR SIR, 



Knowing the enlarged and liberal views which you'' take of 

 medical education, and your willingness to encourage your stu- 

 dents in all inquiries tending to render them skilled and accom- 

 plished in their profession, allow me to lay before you this humble 

 attempt to show the uniformity of the organic laws in plants and 

 animals.
