iving.

5. I think I have not had as many colds and febrile attacks as before,
nor have they been so severe; yet I cannot be very decisive on this
point, on account of the length of time in the trial not being fully
sufficient.

6. Between seven and eight months. I must here state that animal food
was not _entirely_ excluded. I probably partook, in very moderate
quantities, once or twice a week.

7. The quantity of animal food which would be considered "an uncommon
proportion," I am unable to determine; but I was accustomed to make use
of it, not _less_ than twice, and sometimes three times a day,
moderately seasoned. No other stimulants, of any account.

8. Cold water has been the only substitute for tea and coffee, with the
exception of an occasional cup; probably as often as once or twice a
week. I was, on several occasions, by personal experience, induced to
believe that the use of strong coffee retarded the process of
digestion.

9. More aperient. Previous to the general exclusion of animal food from
my diet, I was subject to inveterate costiveness; cases of which are now
neither frequent nor severe.

10. I do firmly believe it would.

11. My diet, principally, during the trial, consisted of wheat bread, of
the proper age, with a moderate quantity of fresh butter. Potatoes,
beans, and some other esculent roots, etc., I found to be nutritious and
healthy. The following substances I found to produce a contrary effect,
or to possess different qualities: cabbage, when not well boiled;
cucumbers, raw or pickled; radishes, beets, and the whole catalogue of
preserves. Fresh bread was particularly hurtful to me.

Yours, etc.,
JOSIAH BENNETT.

LETTER XV.--FROM WILLIAM VINCENT, ESQ.[2]

HOPKINTON, R. I., Dec. 23, 1835.

SIR,--The following answer to the interrogations in the Boston Medical
and Surgical Journal of March 1835, on diet, etc., as proposed by
yourself, has been through the press of business, neglected until this
late period. Trusting they may be of some use, I now forward them.

1. Rather increased, if any change.

2. ----

3. I think I have retained the vigor of my mind more, in consequence of
an abstemious diet.

4. I thought I had the appearance of scurvy, which gradually
disappeared.

5. ----

6. From May 20, 1811, (more than twenty-four years.)

7. Small in quantity, and dressed and cooked simply.

8. I have drank nothing but warm tea, for seven years.

9. Bowels
