But for a painful and rapidly deepening conviction, that the profession of a teacher, which I had embraced with all my heart, would, in the higher departments, bring me into constant collision with my idea of use as the aim and purpose of a manly life,--but for this, I should never have turned to the profession of medicine. Gladly would I exchange all that the classics gave me, for a familiarity with any one of several natural sciences, which I had but little time to examine during my school days. The colleges and universities are rapidly emerging from this darkness of the past. DANCING. During the years of our school in Lexington, we danced from two to four evenings a week. Beginning about half past seven o'clock, we danced till half past eight, which was always our bed-time. In our school family there were several gentlemen, among them the revered Theodore Weld,--our most inveterate dancer. The round dances were not admitted, for the following reasons:-- 1st. The rotary motion is injurious to the brain and spinal marrow. 2nd. The peculiar contact between the man and the woman, may suggest impure thoughts. I have many times asked young men what they thought of it, and after saying it was jolly, that they liked it first-rate, they have generally, when urged to tell me seriously their convictions, confessed that, knowing how men feel and sometimes talk about it, if they were women, they should not indulge. I never talked with one father or mother who was not gratified with my rule against round dances, while a number of them wrote me the warmest commendation. I wish I was at liberty to publish a letter on this subject, which I received from a well-known lady,--giving the letter entire, with the writer's name. I have requested her to allow me to publish it; but she says the sneers at Puritanism are too much for her. I ask my reader, if a mother, whether, if her daughter were away from home, and attending dancing parties, dancing now with Lieut. S., and then with Capt. W.; in brief, with such gentlemen as the managers choose to introduce to her; whether she would like to know that her daughter was being hugged up, and whisked about in the German? Very few mothers would answer yes, to this question. The square dances are certainly very beautiful, graceful, chaste, and healthful. Besides, in a large and interesting way they are social. A large company may join in these dances. The round dance is another illustration of the tendency toward individual display, so strikingly exhibited in the department of music. How constantly we see at dancing parties a single young lady and gentleman start out alone for a dizzy whirl about the hall. I will not comment upon the wild whirligig of her skirts, for I don't think a girl need be ashamed to show her legs. I only say that her contact with her partner is not a modest one.
