Science_,
mainly a condensed form of his treatises, with the doctrines re-stated, and
in many instances freshly illustrated, and with many important additions.
The year 1870 saw the publication of the _Logic_. This, too, was a work
designed for the use of students; it was based on J. S. Mill, but differed
from him in many particulars, and had as distinctive features the treatment
of the doctrine of the conservation of energy in connexion with causation
and the detailed application of the principles of logic to the various
sciences. His services to education in Scotland were now recognized by the
conferment of the honorary degree of doctor of laws by the university of
Edinburgh in 1871. Next came two publications in "The International
Scientific Series," namely, _Mind and Body_ (1872), and _Education as a
Science_ (1879).

All these works, from the _Higher English Grammar_ downwards, were written
by Bain during his twenty years' professoriate at Aberdeen. To the same
period belongs his institution of the philosophical journal _Mind_; the
first number appeared in January 1876, under the editorship of a former
pupil, G. Croom Robertson, of University College, London. To this journal
Bain contributed many important articles and discussions; and in fact he
bore the whole expenses of it till Robertson, owing to ill-health, resigned
the editorship in 1891, when it passed into other hands. Bain resigned his
professorship in 1880 and was succeeded by William Minto, one of his most
brilliant pupils. Nevertheless his interest in thought, and his desire to
complete the scheme of work mapped out in earlier years, remained as keen
as ever. Accordingly, in 1882 appeared the _Biography of James Mill_, and
accompanying it _John Stuart Mill: a Criticism, with Personal
Recollections_. Next came (1884) a collection of articles and papers, most
of which had appeared in magazines, under the title of _Practical Essays_.
This was succeeded (1887, 1888) by a new edition of the _Rhetoric_, and
along with it, a book _On Teaching English_, being an exhaustive
application of the principles of rhetoric to the criticism of style, for
the use of teachers; and in 1894 he published a revised edition of _The
Senses and the Intellect_, which contains his last word on psychology. In
1894 also appeared his last contribution to _Mind_. His last years were
spent in privacy at Aberdeen, where he died on the 18th of September 1903.
