Now, why did they not break down? Why do we find comparatively few invalids among the educated German girls and women? Are there no other causes at work than a somewhat different climate and, occasionally, a more phlegmatic temperament; or is it because the studies of the modern languages and history, the endless practising of _etudes_ and sonatas, the stooping wearily over some delicate embroidery, is less taxing to the nervous system than Latin and Greek, and the working out of algebraic problems? I am not prepared to say. But grant that a small part of the solution can be found in this difference, there are yet other and deeper causes at work. One of them is that the young German girl, while at school, makes study her sole business. She goes to no parties, visits no balls. She does not waste her hours of sleep or leisure in putting numberless ruffles on her garments, so as to surpass her mother in elegance, nor does she promenade up and down the avenues and flirt with young gentlemen. Her amusements are of the simplest. A walk, or an hour spent in a public garden in her mother's company; occasionally a concert or an opera, which never lasts later than nine or half-past nine; some holiday afternoon, a little gathering of young school-friends, to which gentlemen are not admitted; once or twice a year, perhaps, after she is fifteen, private theatricals or a _soiree_; where she appears in a simple dress, dances under her mother's care, and returns home at eleven o'clock. In this way she manages her strength and husbands her forces for study. Another cause of her better health is the great physical care taken at the critical periods of the month; although, as I have previously said, she continues her studies during these days, if without suffering; I must add, that on the other hand she abstains from all physical exercise like gymnastics or dancing-lessons, protects herself most carefully against cold and wet, sleeps perhaps a little longer in the morning, and instead of taking a walk, lies down for an hour through the day. A party or ball at such a time would be looked upon by the mother with horror, and considered by the girl herself as a great impropriety. The care of her health is at all times, of importance to German women. I have, for instance, very rarely seen them walk in bitter-cold winter weather in a so-called cloak, which left the abdomen entirely unprotected.
