Of the works of creation which occupied so much of his thoughts, the Professor's views may be had by reading the following concluding remarks found in his "Physical Astronomy:" "Whatever doubts may hang over all speculations respecting distant events, either of past or future time, we have reason to believe that our universe will ever exhibit great and useful operations throughout its extensive domains. From the ruins of some celestial bodies others will rise to act a part in the drama of the physical creation in future ages. Though nature's work may all decay, her laws remain the same, and numerous agencies, obedient to their control and aided by occasional interventions of creative power, must maintain the heavens forever in a harmonious condition and transform innumerable spheres into seats of light and intelligence. While the laws of nature have been thus widely ordained for such great ends, their simplicity renders them intelligible to the limited powers of the human mind, and the immense universe thus becomes a vast field of intellectual enjoyment for man." TESTIMONY OF THE LATE DR. JOHN HANCOCK. The late Dr. Hancock, in writing to Mrs. J. W. McLaughlin, stated that he attended institute lectures of Prof. Vaughn, making his acquaintance at a meeting of the Southwestern Ohio Normal Institute. The Professor was engaged to lecture on his favorite specialties, physical geography and astronomy. "It is my recollection," says the doctor, "that Prof. Vaughn was a graduate of Trinity Collage, Dublin. However that may be, there can be no doubt as to his wide and profound scholarship. He was not only deeply versed in the physical sciences, but was equally proficient in the classics and mathematics. It is said by competent judges that he read Greek and Latin as he would English, as though he thought in those languages, and he was one of the few Americans who read through Laplace's 'Mechanique Celeste.' He had a prodigious memory. At the Oxford Institute, to which I have referred, some dozen of the leading members, Prof. Vaughn among them, got up some literary games requiring wide reading and retentive memories for successful rivalry. In these games the Professor showed a wealth of reading and an ability to use it on the instant that I have never seen approached by any other scholar. It is needless to say that he was first in the game and the rest nowhere. "Some ten years afterward, when connected with Nelson's Commercial College, I edited a little educational paper, the News and Educator, of which Mr. Nelson was proprietor. In this relation I came much more frequently in contact with Prof. Vaughn than I ever did before. To this paper he contributed a number of articles on scientific subjects, but, being printed in an obscure local paper, they attracted little attention." REMINISCENCES OF MRS. STAMPS.
