LIGHT, CALCIUM, PHOSPHORUS
 AND LONG YOUTH

The main chemical elements com- posing the teeth are calcium and phosphorus, and adequate daily in- take of vitamin D is essential for the utilization of these elements from food or medicine.
 Original source of all vitamin D is sunlight, particularly the ultra violet rays of sunlight-not violet, but invisible colorless rays beyond the blue, indigo and violet in the spectrum of sunlight. These invis- ible colorless rays of sunlight are the ones that produce Sunburn and tan. They are the rays of light that produce the chemical change in the photographic film or plate. They are the rays that bleach. They produce vitamin D in the teeming diatomS and plankton in the sea, these are eaten by larger fish, which are in turn eaten by still larger fish, and so the fish caught for human food have stored in their flyers consid- erable vitamin D.
 Ultraviolet sunlight produces some vitamin D in growing plants, for aside from sea fish oils or fish liver oils, egg yolk and butter or milk fat are the only sources of appreciable amounts of vitamin D in mans na- ural food. If hens are exposed to sunshine, or to ultraviolet light from artificial source, their eggs will con- tain more vitamin D. Likewise cows exposed to sunshine or ultraviolet rays from lamps give milk contain ing more vitamin D. If the feed of fowls or cows is irradiated with ul- traviolet light the eggs or milk will have more vitamin D. One way to produce what is now known as Vita min D milk is by feeding the dairy animals a sufficient amount of ir- radiated yeast daily. Another way is to irradiate the milk itself with ultraviolet light.
 Most children obtain their limited supply of. vitamin D directly from sunshine during the summer months only-even if the youngsters wanted to expose their skin to sunshine in other seasons, the oldsterS would not permit it, being badly taught about that by old fogy physicians and health authorities-but group of 325 infants and children who re- ceived adequate daily rations of vita mins B, G and D. to supplement their dfaily quart of milk, green leafy vegetables, fresh fruits or fruit juices and eggs, for period of 2 1-2 years, showed not single decayed tooth in that time. (Medical Rec- ord, Vol. Al, 346.)
 From a study of the influence of vitamin D in the prevention of car- ies (tooth decay) P. c. Anderson and five associates q. Am. Dent. Assn. 21, 1349, 193N concluded that vitamin D definitely lnhibits the progress of established. carries in the temporary or baby teeth and slightly decreases progress of carries in per- manent teeth.
 McBeath (Am. J. Pub. Health, 24, 1928. 1934) showed that the de- gree of control of decay of the teeth depends on the adequacy of the daily dose of vitanain D.
 As go the teeth so go nerves, the arteries, the vital organs. On other occasions I have said every tooth is worth a thousand dollars. No fool- ing. I believe two or three years are cut off from ones expectation of life for each tooth lost by disease, accident or design.
 Mean Spells
