...personality and taste were evident throughout the exhibition, from the lacy finery she wore on festive occasions (exhibited on dressmaker's dummies at the entrance) to the staggering array of bibelots that had caught the royal eye. There were finely fashioned items of Chinese jade, Chelsea porcelain, Battersea enamel, Neapolitan piqué (tortoise shell or ivory inlaid with gold or silver), case after case of tiny, exquisite baubles, splendid examples of the jeweler's and goldsmith's art. Of small boxes alone -for snuff, beauty patches, or just for decoration-there were 550, plus 120 etuis...

But in 1949, things began to go wrong. Zerbe started suffering from asthma, found that he was allergic to beeswax...
Through research at the University, he and James H. Shaw, assistant professor of Dental Medicine, have discovered that dental enamel is actually composed in part of living organic matter, not of purely inorganic matter, as was formerly supposed. This research has enabled them to learn considerable information about the causes of tooth decay...
...These discoveries," Sognnaes states make clearer what is involved in the decay of a tooth. The micro-organisms that are believed to cause decay. . . are much wider than the individual crystal and organic units that make up the enamel. Hence, before a micro-organism can invade the enamel, both the organic and the inorganic matter (or the bond between the two) must be destroyed or weakened in some...
Sognnaes and Shaw have shown that enamel is also quite dependent on the rest of the body. Using radioactive cancer elements in their University laboratory, they have discovered an unceasingly way traffic of ions in the enamel zone of calcium and phosphorous, a freely exchangeable...
