The last research extended over ten days; the period during which each of
the other subjects was under observation was from 20 to 28 days.

(_a_) The tentative standard for a woman at light work calls for 90
grammes of proteids and 2,500 calories; it is thus seen that the quantity
of food eaten was far below that usually stated as being necessary. The
subject, however, was a very small woman, 5 feet in height, taking almost
no physical exercise. She believed, as do fruitarians generally, that
people need far less raw than cooked food. (_b_) The food eaten was even
less in quantity than in the previous dietary. One reason for this was the
fact that the subject was, for part of the time at least, under great
mental strain, and did not have her usual appetite. Even this small amount
of food, judging by her appearance and manner, seemed sufficient for her
needs, enabling her to do her customary housework and take care of her two
nieces and nephew, the subjects of the other experiments. (_c_) This girl
was given cereals and vegetables when she craved them, but her aunt says
she never looks nor feels so well when she has much starchy food, and
returns to her next meal of uncooked food with an increased appreciation
of its superiority. The commonly accepted dietary standard for a child 13
years old and of average activity, is not far from 90 grammes of proteids
and 2,450 calories, yet the girl had all the appearance of being well fed
and in excellent health and spirits. (_d_) During the 22 days of
experiment, there was an increase in weight of 2 pounds, due to the fact
that the family had been in straitened circumstances, and the food
