7. Before entering upon this diet, I was in the habit of taking a
moderate quantity of animal food, but without very high seasoning or
stimulants.

8. While using this diet, I confined myself entirely and exclusively to
cold water as a drink--using neither tea, coffee, nor spirits of any
kind whatever.

9. I am inclined to think that a vegetable diet is more aperient than an
animal one; indeed, I may say I know it to be a fact.

10. From what I have experienced, I do not think that laborers would be
any more healthy by excluding animal food from their diet entirely; but
I believe it would be much getter if they would use less. As to
students, I believe their health would be promoted if they were to
exclude it almost, if not entirely.

11. I never have selected any vegetables which I thought to be more
healthy than others: nor indeed do I believe there is any one that is
more healthy than another; but believe that all those vegetables which
we use in the season of them, are adapted to supply and satisfy the
wants of the system.

We are carnivorous, as well as granivorous animals, having systems
requiring animal, as well as vegetable food, to keep all the organs of
the body in tune; and perhaps we need a greater variety than other
animals.

Yours, etc.,
LYMAN TENNY.

LIBERTY COUNTY, Georgia, July 15, 1835.

SIR,--Having observed, in the May number of the "American Journal of the
Medical Sciences," certain inquiries in relation to diet, proposed by
you to the physicians of the United States, I herewith transmit to you
an account of a case exactly in point, which I hope may prove
interesting to yourself, and in some degree "assist in the settlement of
a question of _great interest_ to the _country_."

The case, to which allusion is made, occurred in the person of a very
intelligent and truly scientific gentleman of this county, whose regular
habits, both of mind and body, added to his sound and discriminating
judgment, will tend to heighten the value and importance of the
experiment involved in the case I am about to detail.

Before proceeding to give his answers to your interrogatories, it may be
well to premise, that at the time of commencing the experiment, he was
forty-five years of age; and being an extensive cotton planter, his
business was such as to make it necessary for him to undergo a great
deal of exercise, particularly on foot, havin
