pamphlet contains a paper on the above subject, read before the Odontological Society of New York. Irregularity of teeth is shown to arise from three causes: 1. During the life of the individual, from cerebral disturbance while the teeth were forming; 2. Or before the individual life commenced, from like causes transmitted; or, 3. From mixing inharmonious types, large teeth with small jaws.

In this paper, reprinted from the proceedings of the Hartford meeting of the American Association for the Advancement of Science, Prof. Grote summarizes the results of five seasons' observation of the cotton-worm in the States of Georgia and Alabama. Where the moth first came from, its powers of flight, breeding habits, and the measures to be taken against its ravages, are among the interesting questions discussed.

The American Engineer, published monthly at Baltimore, begins its third volume in enlarged form. Though primarily this journal addresses inventors and mechanics, it will be perused with interest by the general reader, who will find in its pages much useful scientific and industrial information, $1.00 per annum.
