[66] By the friend to whom I owe Appendix 21.

[67] One is glad to hear from Cuvier, that though dolphins in general
are "les plus carnassiers, et proportion gardee avec leur taille,
les plus cruels de l'ordre;" yet that in the Delphinus Delphis,
"tout l'organisation de son cerveau annonce _qu'il ne doit pas etre
depourvu de la docilite_ qu'ils (les anciens) lui attribuaient."

[68] Vide Wilkinson, vol. v., woodcut No. 478, fig. 8. The tamarisk
appears afterwards to have given the idea of a subdivision of leaf
more pure and quaint than that of the acanthus. Of late our
botanists have discovered, in the "Victoria regia" (supposing its
blossom reversed), another strangely beautiful type of what we may
perhaps hereafter find it convenient to call _Lily_ capitals.

CHAPTER XXI.

TREATMENT OF ORNAMENT.

Sec. I. We now know where we are to look for subjects of decoration. The
next question is, as the reader must remember, how to treat or express
these subjects.

There are evidently two branches of treatment: the first being the
expression, or rendering to the eye and mind, of the thing itself; and
the second, the arrangement of the thing so expressed: both of these
being quite distinct from the placing of the ornament in proper parts of
the building. For instance, suppose we take a vine-leaf for our subject.
The first question is, how to cut the vine-leaf? Shall we cut its ribs
and notches on the edge, or only its general outline? and so on. Then,
how to arrange the vine-leaves when we have them; whether symmetrically,
or at random; or unsymmetrically, yet within certain limits? All these I
call questions of treatment. Then, whether the vine-leaves so arranged
are to be set on the capital of a pillar or on its shaft, I call a
question of place.

Sec. II. So, then, the questions of mere treatment are twofold, how to
express, and how to arrange. And expression is to the mind or the sight.
Therefore, the inquiry becomes really threefold:--

1. How ornament is to be expressed with reference to the mind.

2. How ornament is to be arranged with reference to the sight.

3. How ornament is to be arranged with reference to both.

Sec. III. (1.) How is ornament to be treated with reference to the mind?

If, to produce a good or beautiful ornament, it were only necessar
