I have found it in many of the higher animals distinctly developed, particularly in the dog and horse.

10th. KINDNESs is between 9th and 14. It gives height to the forehead above 14. Sometimes that part which is next to 9th is large, and that which is nearest to 14 is small, and sometimes the reverse is true. I have found the former oftenest in women, and the latter in men. When the front part of 10th is large, it is manifested more intellectually and deliberately than when the back part is largest; the latter act more by impulse, the former by reason-see the difference between Burr and his daughter Theodosia in this respect; contrast also the heads of Socrates, and West, and W. H. H., with the Parricide, and with Mrs. Rapp.

11th. IMITATIVENESS is situated on the side of 10th, and runs parallel with it; the convolution, (see view of the brain,) originates with 9th, and runs forward into 14 and 15; thus indicating its true and natural relation to those organs. See Socrates and West, and contrast their heads in that part with that of Red Jacket's wife, and with Mrs. Rapp.

12th. CREDENCIVENESS also originates at 9th, borders upon XII, and runs forward to 15. It gives both height and width to the upper lateral part of the forehead, before XII, above XI, and at the outside of 11th. Observe in this organ, the great contrast between the heads of Paine, Hume, and Gibbon, in whom 12th is small, and the heads of Socrates, West, and Lougel, in whom it is very large. I have observed that when the front part of 11th and 12th is much developed, and the back part but little developed, the manifestation was very different from the cases in which the back part of these organs is large, and the front part small: the latter seem to have a greater desire to know, to be curious, to inquire, to understand human nature—in short, to use these conforming social propensities in combination with the intellect; while the former are apt to act upon impulse,

to take testimony upon trust, and to sympathise ignorantly and indiscriminately. This explains why the authors, and painters, and orators, who have been most felicitous in their discriptions of human nature, have high foreheads, while those who have written best upon natural science, or excelled in the useful arts, have low foreheads; or, at least, the intellect (particularly the lowest Range,) has been greater than the high Propensities that border upon it. In examining the Socials, we should be careful to study the proportion and relation which they bear to each other; for upon this there is much more depending than has been supposed. I have found, for instance, that an individual who had 8th above medium, would be false to friends if 4th was small; whilst he would not on any account be known to be dishonest, or even suspected, lest his large 6th should be disagreeably affected. I also know men with moderate IX, and 4th, and large 1st, with 8th more than medium, who will be false in their professions to their female friends, and true to their mercantile friends. It is therefore obviously a task which requires an experienced and discriminating mind, to combine the developements and judge correctly of results in all cases.

In learning the location of the organs, it will be necessary to have the use of a skull to ascertain the bony processes, and sinuses, and sutures, that are apt to mislead the novice; and it will be still better to have access to a collection of skulls. A plaster-of-Paris casting of the brain, will also be very useful, to those who wish to study the science minutely. For the benefit of those who have not an opportunity to examine the brain, or its castings, I have designed, with great care, a view of the base, and of the side of the brain, (see plate 1.) showing the convolutions as I think they will generally be found in the head. Perhaps the side view is, on some accounts, preferable to any casting, or even a real
