TYGON
Chemist Need Good Wives DEAR SIR:
Percentage-wise, yes, and dollar-wise, too, the money any laboratory spends for laboratory tubing amounts to little. But the cost of using inferior quality tubing can be extremely high. Contam ination of a single solution might cost more than a year's supply of tubing. That's basically why laboratories the world over use Tygon plastic tubing — insist on Tygon — refuse to accept tub· ing sold as "just as good as Tygon/' For laboratory technicians know Tygon is the one tubing completely "zieutral" — neither affecting nor being affected by virtually any solution they might use. Add to this outstanding and proven quality: Glass-clearness, string-like flex ibility, unmatched coupling ease, and an availability in a range of sizes to meet every need — and it's easy to see why TYGON is the accepted standard of laboratories everywhere.

The thoughts expressed by Mrs. Robert T. Keen (C&EN, Nov. 18, 1957, page 9) are not new and have been heard on every campus in the U. S. for years. One hears more and more these days about the shortage of scientists. What one does not hear about is the num ber of scientists we have lost because a young student was faced with the choice of graduate work or the girl he loved. Often the young lady, sensing that his choice will be graduate work, agrees to marriage, then begins a cam paign which results in his dropping out of school (with a master's degree, if he is lucky) to accept a position which will allow her to enjoy a "decent standard of living." Λ great fraction of the graduate student's life is spent in study at a time when he is young enough, human enough, and virile enough to need and deserve the love, understanding, help, and cooperation of a good wife. The young wife of today does not seem to realize the wonderful opportunity Ae has to contribute to the development of her husband, her children, and her self, and to society as a whole. No longer need she be merely a cook, housekeeper, and baby factory but through her husband she can help-noassure a longer, happier, more fruitful and disease-free life for her children and all other children. I suggest that those wives of gradu ate students who are dissatisfied with their lots sit down in their "substand ard" housing and consider their chil dren. How many diseases that would have killed them 20 years ago are they now protected against? Does the as surance that they will probably never labor for breath in an iron lung comfort her? Does the fact that, in the span of 100 years, mothers lost in childbirth went from 50% down to almost noth ing, give her cause for joy? As she considers her "substandard student liv ing" can she find anything sdenoe has given her? Her aluminum pots, nylons, Salk vaccine, antibiotics, automobile (may be old, but ever try riding a horse to the supermarket?), soap, paints (nail polish included), TV set,
