Punchinello, Volume 1, No. 20, August 13, 1870

Educational and Scientific Lectures, Addresses and Essays, brought out in neat pamphlet form, of uniform style and price.

I.--"ON THE PHYSICAL BASIS OF LIFE." By Prof. T. H. HUXLEY, LL. D., F. R. S. With an Introduction by a Professor in Yale College. 12mo, pp. 36. Price 25 cents.

The interest of Americans in this lecture by Professor HUXLEY can be judged from the great demand for it; the fifth thousand is now being sold.

II.--THE CORRELATION OF VITAL AND PHYSICAL FORCES. By Prof. GEORGE F. BARKER, M. D., of Yale College. A Lecture delivered before Am. Inst., N.Y. Pp. 36. Price 25 cts.

"Though this is a question of cold science, the author handles it with ability, and invests it with interest. A series of notes appended is valuable as a reference to works quoted."--Prov. (R. I.) PRESS.

III.--AS REGARDS PROTOPLASM, in Relation to Prof. HUXLEY'S Physical Basis of Life. By J. HUTCHINSON STIRLING, F. R. C. S. Pp. 72. Price 26 cents.

By far the ablest reply to Prof. HUXLEY which has been written.

Other valuable Lectures and Essays will soon be published in this series.
