mal food from their diet for a year or over, to lend them
this number of the Journal, and ask them to forward to Milo L. North,
Hartford, Connecticut, as early as convenient, the result of this change
of diet on their health and constitution, in accordance with the
following inquiries?

"1. Was your bodily strength either increased or diminished by excluding
all animal food from your diet?

"2. Were the animal sensations, connected with the process of digestion,
more--or less agreeable?

"3. Was the mind clearer; and could it continue a laborious
investigation longer than when you subsisted on mixed diet?

"4. What constitutional infirmities were aggravated or removed?

"5. Had you fewer colds or other febrile attacks--or the reverse?

"6. What length of time, the trial?

"7. Was the change to a vegetable diet, in your case, preceded by the
use of an uncommon proportion of animal food, or of high seasoning, or

"8. Was this change accompanied by a substitution of cold water for tea
and coffee, during the experiment?

"9. Is a vegetable diet more--or less aperient than mixed?

"10. Do you believe, from your experience, that the health of either
laborers or students would be promoted by the exclusion of animal food
from their diet?

"11. Have you selected, from your own observation, any articles in the
vegetable kingdom, as particularly healthy, or otherwise?

"N.B.--Short answers to these inquiries are all that is necessary; and
as a copy of the latter is retained by the writer, it will be sufficient
to refer to them numerically, without the trouble of transcribing each
question.

This circular, or letter, drew forth numerous replies from various parts

prize of the Boylston Medical Committee was awarded to Luther V. Bell,
M.D., of Derry, New Hampshire, and was published in the Boston Medical
and Surgical Journal, and elsewhere, and read with considerable
interest.

In the year 1836, while many were waiting--some with a degree of
impatience--to hear from Dr. North, his health so far failed him, that
he concluded to relinquish, for the present, his inquiries; and, at his
particular request, I consented to have the following card inserted in
the Boston Medical and Surgical Journal:

"DR. NORTH, of Hartford, Connecticut, tenders his grateful
