_Dr. Elder’s Address._—We lately received a copy of an address, delivered before the Penn Institute of Pittsburgh, Pa., February 28th, 1839, by William Elder. It is truly encouraging to find so many friends and advocates of our new science. It is now becoming the theme of many public addresses and lectures, as well as leading articles in our regular periodicals. There are also some who make a free use of its principles, and very advantageously too, without employing its technical language, or even giving due credit to the science. It is a fact, that whenever and wherever truth on any subject is presented, in harmony with the principles of phrenology, it will appear clearer, more consistent and convincing to every mind, and consequently will be more powerful in its effects. It is as certain as any mathematical demonstration can be, that if phrenology is a _true interpretation_ of human nature, that all truth connected with mind, and presented in harmony with the laws of its correct interpretation, must touch a cord that will vibrate in every person, though perhaps feebler in some than in others. We have known many individuals very much pleased, and even captivated by a certain production or performance, and to affirm repeatedly that the subject was never discussed before so clearly and satisfactory to their minds; but when they were afterwards informed that it was treated upon _strictly phrenological principles_, they are much surprised, and sometimes seem _mortified_. How true, in spite of prejudice and opposition, is the Latin proverb—“_Magna est Veritas et prævalebit_.” But to return to Dr. Elder’s address. We have perused it with much interest. It appears that this address was delivered before an association of young men, formed for mutual improvement. The principal object of the author was to unfold the great laws of mind, a knowledge of which is so important to mental and moral improvement. A subject more appropriate to the occasion could not well have been selected; and how far the author succeeded in accomplishing his object, we shall take pleasure in giving our readers an opportunity to judge for themselves, by presenting several extracts in the next number of the Journal. The article promised in our last, on the “Elementary Principles of Phrenology,” is necessarily deferred till the next number.
