the public having done me the honour to 

 have purchased the first edition, and good 

 part of the second, assures me it cannot 

 now be suppressed ; and whether the im- 

 provements I had established, were or were 

 not received and treated as they deserved, 

 time will show. Every man has a right to 

 confide in his own understanding, and if 

 his conscience does not accuse him of having 

 presumed to violate truth, or pluming him- 

 self on his fancied powers, to have imposed 

 false and untried theories on the ignorant 

 and credulous, he need not fear others. 

 Fortune may enable pride and arrogance to 

 smother truth and science for a time, but 

 in a land of liberty these must ultimately 

 establish themselves, however humble their 

 immediate patrons. Although the Horti- 

 cultural Society of London have refused to 

 acknowledge the merit of my arrangement 

 and explanation of scientific principles, 

 they must ultimately adopt them, or be 

 left far in the back ground, and their gar- 

 den exhibit a glaring instance of a want 



of candour and liberality in the directors.
