ed in the Lecture above referred to. See what Dr. John Hughes
Bennett says of it in the recent edition of his work on Medicine.
Nothing but the most careful clinical experience can settle this and such
points of treatment.

These are all practical questions--questions of life and death, and every
day will be full of just such questions. Take the problem of climate. A
patient comes to you with asthma and wants to know where he can breathe;
another comes to you with phthisis and wants to know where he can live.
What boy's play is nine tenths of all that is taught in many a
pretentious course of lectures, compared with what an accurate and
extensive knowledge of the advantages and disadvantages of different
residences in these and other complaints would be to a practising
physician.

I saw the other day a gentleman living in Canada, who had spent seven
successive winters in Egypt, with the entire relief of certain obscure
thoracic symptoms which troubled him while at home. I saw, two months
ago, another gentleman from Minnesota, an observer and a man of sense,
who considered that State as the great sanatorium for all pulmonary
complaints. If half our grown population are or will be more or less
tuberculous, the question of colonizing Florida assumes a new aspect.
Even within the borders of our own State, the very interesting researches
of Dr. Bowditch show that there is a great variation in the amount of
tuberculous disease in different towns, apparently connected with local
conditions. The hygienic map of a State is quite as valuable as its
geological map, and it is the business of every practising physician to
know it thoroughly. They understand this in England, and send a patient
with a dry irritating cough to Torquay or Penzance, while they send
another with relaxed bronchial membranes to Clifton or Brighton. Here is
another great field for practical study.

So as to the all-important question of diet. "Of all the means of cure
at our command," says Dr. Bennett, "a regulation of the quantity and
quality of the diet is by far the most powerful." Dr. MacCormac would
perhaps except the air we breathe, for he thinks that impure air,
especially in sleeping rooms, is the great cause of tubercle. It is
sufficiently proved that the American,--the New Englander,--the
Bostonian, can breed strong and sound children, generation after
generation,--nay, I have shown by the record of a particular family that
vital losses may be re
