rthy how the relations of medicine to the welfare of man
always occupied his attention. Thus we find, in one sent from England,
June, 1870, a description of the Liverpool Medical Missionary Society,
a charity which combines religious instruction with medical advice; and
again, he comments on the popular instruction in hygiene which was
supplied at that period to the English workingmen by a committee of
competent physicians, organized for that purpose. It was the author's
purpose to collect and expand these letters into a volume, but the
project was not carried out.

The siege of Paris, which city he left in one of the last trains before
the blockade commenced, and the prolongation of the war, induced him to
return home. In the United States he found offers from several
publishers awaiting him, which would more than occupy him for a full
year. There was a new edition of his "Therapeutics" demanded, and a
revision of both "The Physical Life of Woman" and "The Transmission of
Life." A New England firm urgently pressed him to superintend the
production of several hygienic works, and secured him as literary
adviser to their house. He assumed the editorship of the "Half-Yearly
Compendium of Medical Science," and also of a "Physician's Annual,"
besides undertaking a number of articles for the periodical press, both
scientific and popular.

To this active literary life he devoted the year 1871; but at its close
felt more strongly than ever that he must give himself several years of
studious quiet, in order to accomplish his best. Refusing, therefore,
any further engagements, he sailed for Europe again, late in 1871, and
did not return this time until the spring of 1875. In this period, of
more than three years, he visited almost all the principal cities of
Europe, and enjoyed the friendship of many eminent men at London, St.
Petersburg, Vienna, and Paris. Reading, visiting hospitals, and
attending clinics, he accumulated a mass of material which he designed
to work up into future literary enterprises.

With these collected stores he returned to the United States early in
1875, and set to work with his wonted energy. A new and much enlarged
edition of the "Therapeutics" was sent to press; a "Handbook of Popular
Medicine," designed to give, in simple language, the domestic treatment
of disease, the rules for nursing the sick, selected receipts for diet
and medicinal purposes, and the outlines of anatomy and physiology, was
