apparently at variance with this, has recently been taught, with great confidence, among the professed discoveries of Phrenology. How much truth there may be in this new "science," as it is called, I am not prepared to say; but, as sometimes held forth, it seems to me not only to clash with some of the most important principles of mental philosophy, but to make the power of thought the result of that which is in itself inert and unthinking. Assuming that the primitive faculties of the human understanding have not been known in earlier times, it professes to have discovered, in the physical organization of the brain, their proper source, or essential condition, and the true index to their measure, number, and distribution. In short, the leading phrenologists, by acknowledging no spiritual substance, virtually deny that ancient doctrine, "It is not in flesh to think, or bones to reason," [42] and make the mind either a material substance, or a mere mode without substantial being.

"The doctrine of immaterial substances," says Dr. Spurzheim, "is not sufficiently amenable to the test of observation; it is founded on belief, and only supported by hypothesis."--Phrenology, Vol. i, p. 20. But it should be remembered, that our notion of material substance, is just as much a matter of hypothesis. All accidents, whether they be qualities or actions, we necessarily suppose to have some support; and this we call substance, deriving the term from the Latin, or hypostasis, if we choose to borrow from the Greek. But what this substance, or hypostasis, is, independently of its qualities or actions, we know not. This is clearly proved by Locke. What do we mean by _matter_? and what by _mind_? Matter is that which is solid, extended, divisible, movable, and occupies space. Mind is that which thinks, and wills, and reasons, and remembers, and worships. Here are qualities in the one case; operations in the other. Here are two definitions as totally dis
