require some new principles of right and wrong in these matters, some force of opinion, which may, indeed, be already heard whispering in private, but has never affected the moral sentiments of mankind in general. We unavoidably lose sight of the principle of utility, just in that action of our lives in which we have the most need of it. The influences which we can bring to bear upon this question are chiefly indirect. In a generation or two, education, emigration, improvements in agriculture and manufactures, may have provided the solution. The State physician hardly likes to probe the wound: it is beyond his art; a matter which he cannot safely let alone, but which he dare not touch:
“We do but skin and film the ulcerous place.”
When again in private life we see a whole family one by one dropping into the grave under the Ate of some inherited malady, and the parents perhaps surviving them, do our minds ever go back silently to that day twenty-five or thirty years before on which under the fairest auspices, amid the rejoicings of friends and acquaintances, a bride and bridegroom joined hands with one another?

The late Dr. Combe is said by his biographer to have resisted the temptation to marriage, because he knew that he was subject to hereditary consumption. One who deserved to be called a man of genius, a friend of my youth, was in the habit of wearing a black ribbon on his wrist, in order to remind him that, being liable to outbreaks of insanity, he must not give way to the natural impulses of affection: he died unmarried in a lunatic asylum.

If we could prevent such marriages without any violation of feeling or propriety, we clearly ought; and the prohibition in the course of time would be protected by a horror naturalis similar to that which, in all civilized ages and countries, has
