ls whose habitat is in dry places, is to be preferred
to that of ducks and geese. Of fish, only those provided with scales
should be eaten, and all forms of milk should be avoided, except whey,
"which purifies the body of superfluities." Fruits are to be eschewed,
except acid pomegranates, whose juice cools the stomach and relieves
thirst. Boiled meats, seasoned with herbs like sage, parsley, mint,
saffron, etc., are better than roasted meats, and onion and garlic are
to be avoided.

The primitive conditions of land travel in the days of Gilbert are
emphasized by his minute directions for the care of the feet, which he
directs to be rubbed briskly with salt and vinegar and then anointed
with an ointment of nettle-juice (_urtica_) and mutton-fat, or with
a mixture of garlic, soap and oil. If badly swollen, they should be
bathed, before inunction, with a decoction of elder-bark and other
emollients.

In travel by sea, Gilbert tells us the four chief indications are to
prevent nausea, to allay vomiting, to palliate the foul odor of the
ship and to quiet thirst.

For the prevention of nausea he recommends the juice of acid
pomegranates, lemons, etc., or a decoction of parsley or sweet cicely
(_cerfolium_). The traveler should endeavor to sit with his head
erect, should avoid looking around, but maintain his head as immovable
as possible, and support himself by a firm grasp upon some beam of the
ship. Some sweets may be sucked, or he may chew a few aromatic seeds.
If vomiting ensues, acid or sweet pomegranates, figs or barley-sugar
(_penides_) may be taken sparingly, but no food should be ingested
until the stomach is thoroughly quieted. Then the patient may take a
little _stomatichon_ or _dyantos_, and a small portion of digestible
food. As the diet must necessarily consist largely of salty food and
vegetables, these should be cooked in three or four different waters,
and then soaked in fresh water. A little aromatic wine will also
benefit the patient, and a few aromatic seeds chewed in the morning
are also of service.

The effect of the foul odors of the ship may be combatted by the use
of aromatic electuaries, "which comfort the heart, the brain and the
stomach." The patient should be removed to some quiet portion of the
ship, as distant as possible from the channels for the discharge of
the bilge-water, and short walks upon the upper deck will contribute
to convalescence. Frequent changes of clothing will palliate t
