observations. The facts they embrace are the result of admeasurements; and, as far as they extend, they put at rest the question of the relative magnitude of the Caucasian brain. We feel persuaded that, as soon as they shall be made known to him, even Tiedemann himself and his stubborn adherents, hostile as they are to the doctrines of phrenology, will cease to contend that the brain of the African is equal in size to that of the Caucasian. With equal truth may they contend for identity in the colour of the skin, the figure of the nose, and the entire character of the lips and hair of the two Races. Never were the blindness and deceptiveness of professional prejudice more doggedly manifested. The following are the observations to which we allude.

NOTE.—On the Internal capacity of the Cranium in the different Races of men.-Having subjected the skulls in my possession, and such also as I could obtain from my friends, to the internal capacity measurement already described, I have obtained the following results. The mean of the American Race (omitting a fraction) is repeated here merely to complete the table. The skulls of idiots and of persons under age were of course rejected.

"Races.

No of Skulls. Mean internal capacity in cubic inches. Largest in the series. Smallest in do.

"1. The Caucasians were, with a single exception, derived from the lowest and least educated class of society. It is proper however to mention that but three Hindoos are admitted in the whole number, because the skulls of these people are probably smaller than those of any other existing nation. For example seventeen Hindoo heads give a mean of but seventy-five cubic inches."

After a few farther remarks on the Caucasians, Mongolians, Malays, and Ethiopians, which it is not important for us to quote, Dr. Morton subjoins:

"5. Respecting the American Race, I have nothing to ad excepting the striking fact, that, of all the American nation the Peruvians had the smallest heads, while those of th Mexicans were something larger, and those of the barbaro. tribes the largest of all, viz:

"An interesting question remains to be solved, viz: relative proportion of brain in the anterior and poster chambers of the skull in the different races; an inquiry which I have hitherto possessed neither sufficient leisure, adequate materials."

As connected with this question, and tending toward a lution of it, the following statement is worthy of notice.

On comparing with each other an American and a Cate sian brain, very nearly equal in size, and each being in fo about an average of its race, the size of the three lobes materially different.

In the Caucasian brain, the front lobe, which is the se intellect, was much larger than in the American, and its · volutions considerably bolder and more prominent.

In the American brain, the middle lobe, the seat of animal and the semi-animal propensities, was in an e degree larger than in the Caucasian, and its convolut deeper.

ART. VI.—Elements of Pathological Anatomy, illustrated by numerous engravings. "In Morbis, sive acutis, sive chronicis, viget occultum, per humanas speculationes incomprehensible." Baglivi. By SAMUEL D. GROSS, M.D. Late professor of General Anatomy, Physiology, and Pathological Anatomy, in the Medical Department of the Cincinnati College. Vol. II, 8vo., Boston, 1839. Marsh, Capen, Lyon

& Webb and James B. Dow.

MANY of our brethren must well remember the time, when the only work on Morbid Anatomy within their reach, was the little volume of 250 pages, from the pen of Dr. Matthew Baillie of London, re-printed in Albany in 1795. It was altogether special. Since that date, such has been the progress of this new department, that the general has been added to the special-systems have been formed, and a new branch of science created. Previously, however, to the re-publication in this country, of Andral's celebrated "Treatise on Pathological Anatomy," eight years ago, the American student had but meagre opportunities for the prosecution of this most interesting and useful study. The advancement which has been made since that work appeared, may be inferred from the fact, that several medical schools have been enriched with professorships of Morbid Anatomy, and, still more, from the fact now before us, that a physician of our own country-a practitioner of the west-has brought out a well-digested work of equal extent, and greater simplicity than Andral's, which, we learn, is every where well received by the profession.

The eminent French pathologist attempted to present the facts of this science, by a method that would disclose the origin of the morbid appearances which he described. Thus he formed the great classes-lesions of circulation—of nutrition, of secretion, of innervation, and of the blood. It is certainly
