THE NATURAL PRINCIPLES of BEAUTY,
As Developed in the Human Figure.

By D. It. HAY, F R.S.E.
" The main points of this treatise are the clear and detailed state-
ment of the principles on which the author's tybtem is based, and
very explicit particulars of its verification by experiment. . . We
cannot refuse to entertain Mr. Hay's system as of singular intilnsic
excellence. The simplicity of his law and its generality impress
themselves more deeply on the conviction with each time of enforce-
ment. His theory proceeds from the idea, that in Nature every-
thing is effected by means more simple than any oilier that could
have been conceived, —an idea certainly consistent with whatever
we can trace out or imagine of the all-wise framing of the universe."
—Spectator, Jan. Ist, 1853.
" This is a treatise which, in its ingenuity not less than its sub-
ject, is exquisitely beautiful . . . Briefly, It is here proved that
man, the image of his Maker, has, even in his low estate, a frame
based on the type of the most perfectly conceivable symmetry. By
founding (if we may so phrase it) this noble theory, Mr. Hay has
covered his name with distinction, and has Did the basis, we con-
ceive, of no ephemeral reputation. By illustrating it anew, through
the medium of this graceful treatise, he has conferred a real boon
upon the community, for he has afforded the public another oppor-
tunity of following the golden rale of the post—by looking thr aigh
the holy and awful mystery of creation, to the holier and yet more
awful mystery of Omnmotence."—The sun, March 17, 1853.

" Au.„,point du vile philosophique ou m,thetique nous comprenons
fort bien l'utilite du travail publie par M Hay . . L'ouvrage est
interessant, et indique des etudes eonsciencieuses."
