and it is but justice to the enterprize and talents of Mr. Tiebout 

 to state thus much. Whether the colouring of the plates alluded to 

 in No. VIII. will be found equal to Michaux's is not for the author, 

 but the public, to decide. Thus much he may with propriety state : 

 that his work on Vegetable Materia Medica contained the first colour- 

 ed engravings of plants which had issued from an American press — 

 they were begun without any information as to the tact employed in 

 this kind of work in England, where it has attained so high a 

 degree of perfection. Owing to the impossibility of obtaining in- 

 formation as to the manner of colouring abroad, he has been obliged 

 to make repeated experiments, and has thus gradually brought it to 

 the style exhibited in the present work. He has now the satisfac- 

 tion of presenting a close imitation of the French method. Both 

 of the different kinds of engraving, (the finished dotted and the 

 line,) will be used in this work in future ; each having its peculiar 

 beauty, advantage, and expression, for presenting pictured imitations 

 of plants of diverse characters and physiognomy. 



In justice to the publishers who have embarked in this, the most 

 extensive original work ever undertaken in this country, it should 

 be mentioned: that the present plan enhances the expense of the 

 work, and, in some measure, lessens the author's profits, while at 

 the same time, the price is not augmented. And as more is given to 

 the subscribers than promised, the Publishers confidently look for 

 an enlarged patronage by an increasing subscription.
