Arrangements of Plants. 57 
frequently divided, but that even species are separated*." To 
these he adds many other objections of minor importance, and. 
afterwards asserts, that “if a preference is to be given to that 
method which is the most easy, and the most agreeable to the 
order of nature, that of "Tournefort is the most perfect ; that the 
arrangement of the Linnean system is sometimes perplexed, its 
designations difficult, and its connections of plants not related 
still more frequent; that it is indebted for its general reception, 
among botanists to the conciseness and certainty of its charac- 
ters, the number of individuals arranged under each order, and 
the improved nomenclature by generic and specific names.” 
To this, however, he adds, ** that all such systems are arbitrarily 
constructed, that they exhibit a factitious science, terminating 
not in thé knowledge, but merely in the defining and naming of 
plants; and that, in short, they can only be considered as a 
prelude to the science of botai y, affording a succedaneous ar- 
rangement of plants, until, by repeated labours, they can be 
reduced into a proper and natural series +.”
