Hydrodynamics, Pneumatics, the Laws of the Motions of Waves
in general, Sound, the Theory of Musical Notes, the Voice and
Hearing, Geometrical and Physical Optics, Magnetism,
Electricity and Galvanism, in all their subdivisions, Heat
and Meteorology, within the space of an ordinary middle-sized
volume. Of the manner in which the translator has executed
his task, it behoves him to say nothing; he has attempted
nothing more than a plain, and nearly literal version of the
original. He cannot, however, conclude this brief
introductory note without directing the attention of his
Readers to the splendid manner in which the Publishers have
illustrated this volume.

_August, 1847._

"The Physics of Muller is a work, superb, complete, unique: the
greatest want known to English Science could not have been better
supplied. The work is of surpassing interest. The value of this
contribution to the scientific records of this country may be duly
estimated by the fact, that the cost of the original drawings and
engravings alone has exceeded the sum of 2000L."--_Lancet_, March,
1847.

"The plan adopted by Muller is simple; it reminds us of the excellent
and popular treatise published many years since by Dr. Arnott, but it
takes a much wider range of subjects. Like it, all the necessary
explanations are given in clear and concise language, without more
than an occasional reference to mathematics; and the treatise is most
abundantly illustrated with well-executed wood engravings.

"The author has actually contrived to comprise in about five hundred
pages, including the space occupied by illustrations, Mechanics, the
Laws of Motion, Acoustics, Light, Magnetism, Electricity, Galvanism,
Electro-Magnetism, Heat, and Meteorology.

"Medical practitioners and students, even if they have the means to
procure, have certainly not the time to study an elaborate treatise in
every branch of science: and the question therefore is, simply,
whether they are to remain wholly ignorant of such subjects, or to
make a profitable use of the labours of those who have the happy art
of saying or suggesting much in a small space.

"From our examination of this volume, we do not hesitate to recommend
it to our readers as a useful book on a most interesting branch of
science. We may remark, that the translation is so well executed, that
we think the translator is doing himself injustice by concealing his
