742 MAN'S PHYSICAL WKLFARE

Dietary surveys which have been conducted by the Department of Agriculture

. . . indicate very clearly that in the neighborhood of one-third of our

entire population are receiving diets which, according to modern standards of

nutrition, are definitely inadequate. Those diets are so poor that while they

supply enough calories — and, of course, all of our population, speaking in

general terms, get enough calories — they are deficient in minerals and vitamins

to such an extent that we see wide-spread symptoms of them. All groups

are affected — it is by no means confined to the low economic groups.'

In 1922 Harry Steenbock discovered that milk and other foods when

irradiated with ultraviolet light were increased in their vitamin-D content.

He patented his irradiation process and turned down fabulous

ofTers for his patents. These patents were turned over to the University

of Wisconsin to create a research fund. Steenbock received ten dollars

for the patent, while the Wisconsin Alumni Research Foundation had

received over $1,400,000 in royalties by 1941. The foundation stipulates

that only major food items shall be irradiated and that the companies

manufacturing these foods may not increase the prices of these

foods because of their irradiation. The foundation also checks all

advertising claims dealing with irradiated foods. Over two billion

pounds of evaporated milk, representing 60 per cent of the evaporated

milk produced in the United States, are irradiated annually, while

many people buy irradiated fresh milk.

Research workers in the Universities of Illinois, Toronto, Cincinnati,

and Purdue, following Harry Steenbock's example, have contributed

patents to similar research foundations. The University of Purdue

owns 145 patents, from which it has already received more than a

million dollars.

Undoubtedly Harry Steenbock receives more real satisfaction from

the knowledge that his patents are enabling many research workers to

extend the frontiers of human knowledge than the owner of a milliondollar

yacht could ever receive from his investment.

Plants Are Stimulated by Vitamin Treatments.

Thiamin chloride has been widely publicized as a stimulant for root

growth to be used especially when transplanting plants.

The majority of plants probably make all the vitamins that they

need, but there are some plants that resemble animals in their inability

to manufacture one or more of the vitamins.

One trillionth of a pound of vitamin Bi produces a measurable effect
