Show Wednesday. November Dental Series Story of Decay Preventing Product By PHILLIP CLARK HALL. D.D.S. How does a new dental product get on the market, and bow is it proved to be safe to sell to the public as an er product? Progress toward the retail marketplace can take several routes and the following is one example. Recently, Dr. Israel Kleinberg. head of the department of oral biology and pathology at State University College, Stony Brook, N.Y., discovered a peptide which has been named Sialin. In laboratory tests, Sialin (having already been successfully synthesized) has shown a potential for reducing tooth decay through its seeming ability to raise the pH level in ther mouth to a point that makes the decay process unlikely. Since many popular foods and most candies cause an acid to form in the mouth, thus setting the stage for decay to begin, negating that acid should cut g the potential. This new peptide if proved safe and effective might be used as an addecay-formin- ditive in foods, mouthwash or toothpastes. Therefore, it is readily understandable why a large company like '" $ 1980. it It. trk THE HERALD. Provo. Utah-Pa- ge 15 It. (..! successful.

Then, according to a new book and an exhibition at the British Museum, travel was not only no fun, it was downright dangerous. So much so that a traveler's friends laid odds he would never get back alive. "Bankrupts and others undertook journeys to gain the money wagered against their return," said the British Library exhibition of early travel guidebooks. Even Fynes Moryson, the first professional travel writer, bet 100 pounds in 1599 with friends who laid 3 to 1 that he would never make it back. It took him four years, but he collected. Moryson also features in a delightful book by J.G. Links, published by the Bodley Head. "Travelers in Europe" has the incidental benefit of travel tips which still sound sensible. Moryson, for instance advised nearly 400 years ago: "And to the end he (the tourist) may leave nothing behind him, let the visiting of his chamber, and gathering his thirj? together, be the last thing he does before he puts his foot into the stirrup." Links in his book rescues the forgotten "postcards" of 22 pioneer travelers, ranging from Horace in 37 B.C. to diarist Samuel Pepys in 1668. Their tales are full of hairraising adventures and hilarious misadventures. Moryson hinted at both by advising the tourist: "In all inns, let him take heed of his chamber fellows and always have his sword by his bedside." Moryson also suggested he "lay his purse under his pillow, but always folded with his garters, or something he first uses in the morning." But the chief delight of these ancient travelers' ac counts is to prove that the more things change, the more they remain the same. English diarist John Evelyn in 1644 encountered "certain persons in Rome who get their living only by leading strangers about to see the city." In England, observed Andrea Trevisano in 1498. "Rain falls almost every day during the months of June, July and August: they never have any spring here." Trevisano, by the way, found the English "great lovers of themselves and of everything belonging to them. They think that there are no other men than themselves, and no world but England." Links compiled "Travelers in Europe" by scouring private diaries and letters from the era when travel was anything but pleasant. Tourism, after all, is leaner than bacon 50 PXG. 12-0- 1.
