" Any man who yields habitually to melancholia may expect his brain, sooner or later, to degenerate from its original strength, and relax the toughness and compactness of its fibre. Absolute dementia may not be the result for some years, but there will be occasional and painful indications of the end for a long space before it arrives. The indications, as a rule, will assume the form of visions and dreams and wild imaginings of various sorts. Now do you understand me? "
