publish these Essays in their present form. I 

 wish I had it in my power to present to his 

 notice some production that would be more 

 worthy of his indefatigable zeal in the cause of 

 science. That he may receive ample patronage 

 from a liberal public, and a remunerating com- 

 pensation for the trouble which he has been put 

 to, is the ardent wish of his sincere friend,
