To return to the theory of cerebral development: The reader will understand by referring to the last chapter that the summit of the spinal system or great inferior ganglion of the brain, bearing the names of optic thalami and corpora striata, is the true beginning of the cerebrum, instead of the medulla oblongata, which _does not_ contain the fibres of the cerebral organs. And as this beginning is a little in front of the ear and its first radiating fibres are nearly on the horizontal line just mentioned, it follows that we may locate accordingly a centre from which cerebral development may be estimated; and when we take this true centre we may describe around it a circle, and find that the circle singularly coincides with the outline of the cranium, so that if we add to that circle the outlines of the nose, mouth, and chin, we have sketched a well-developed head of strong character, and ascertained the method of studying the development of the brain, which has so remarkably been overlooked. [Illustration] No one can begin the study of brain development in men and animals guided by a correct system without being delighted with the uniform accuracy of the science; for even the incomplete and inaccurate science of Gall and Spurzheim, marred in its application by misconceptions of anatomy, has proved sufficiently correct and instructive to maintain its hold upon the minds of all students of nature, by giving them more truth than error, and _sometimes_ giving the truth with marvellous accuracy. The errors they did not attempt to investigate.[4] [4] I would merely mention, as a familiar example of such errors, that an enlightened student of phrenology called upon me yesterday, to whom phrenologists had given the character of avaricious selfishness and an incapacity for friendship, which indeed was the correct application of the old system, but was the reverse of his true character. The old system did not explain friendship correctly, and entirely mislocated the organ of avarice by placing it in the temples. The gentlemen had never before received a correct description from phrenologists he had visited. BUSINESS DEPARTMENT. The establishment of a new Journal is a hazardous and expensive undertaking. Every reader of this volume receives what has cost more than he pays for it, and in addition receives the product of months of editorial, and many years of scientific, labor. May I not therefore ask his aid in relieving me of this burden by increasing the circulation of the Journal among his friends?
