INTEODUCTION TO TASMANIAN FLOEA 485 
conception. I am much influenced too by the progress of 
Physical science and ' Natura nihil facit per saltus.' 
To Bentham 
August 8, 1859. 
Very many thanks for your last letter, and the notes 
on the Essay. I have revised the paragraphs on anomalies, 
but not altered much, as I think that such as they are, the 
peculiarities of the Flora are much more objective than of 
any other Flora, and more pervade the whole vegetation. . . . 
I was afraid of overdoing the pecuharities, and have failed 
to do them justice. I agree with you that my allusion to 
them is not sufficiently discriminative. Take Eucalyptus 
altogether as a genus and it is really a remarkable vegetable, 
considering the number of forms its Bark assumes ; that 
alone would make it notable.
