AËRONAUTICS.
The subject of artificial flight, notwithstanding the large share of attention bestowed upon it, has been particularly barren of results. This is the more to be regretted, as the interest which has been taken in it from early Greek and Roman times has been universal. The unsatisfactory state of the question is to be traced to a variety of causes, the most prominent of which are—
1st, The extreme difficulty of the problem.
2d, The incapacity or theoretical tendencies of those who have devoted themselves to its elucidation.
