But these diets chiefly refer to temperate climates; it
would therefore be a matter of great interest if travellers in distant
lands would accurately observe and note down the weight of their own
rations and those of the natives. It is a great desideratum to know the
lightest portable food suitable to different countries. Any such reports,
if carefully made and extending over a period of not less than two
months, would be very acceptable to me. To make them of any use, it is
necessary that every article consumed should be noted down; and that the
weight and state of health, at the beginning and at the end of the
period, should be compared.
