they are dazzling?"

20. I think, certainly, from the dazzling, which sometimes with the poppy,
scarlet geranium, and nasturtium, is more distinctly oppressive to the eye

I will certainly not include among my rescued Draconidæ, the parasitic
Lathræa and Orobanche; and cannot yet make certain of any minor
classification among those which I retain,--but, uniting Bartsia with
Euphrasia, I shall have, in the main, the three divisions Digitalis,
Linaria, Euphrasia, and probably separate the moneyworts as links with
Veronica, and Rhinanthus as links with Lathræa.

And as I shall certainly be unable this summer, under the pressure of
resumed work at Oxford, to spend time in any new botanical investigations,
I will rather try to fulfil the promise given in the last number, to
collect what little I have been able hitherto to describe or ascertain,
respecting the higher modes of tree structure.

CHAPTER VII.

SCIENCE IN HER CELLS.

[The following chapter has been written six years. It was delayed in
order to complete the promised clearer analysis of stem-structure;
which, after a great deal of chopping, chipping, and peeling of my oaks
and birches, came to reverently hopeless pause. What is here done may
