MACMILLAN & C0.S SCIENTIFIC PUBLICATIONS. 
SCIENTIFIC MANUALS. 
Ir is the intention of the Publishers to produce a complete 
series of Scientific Manuals, affording full and accurate elementary 
information, conveyed in clear and lucid English. The authors 
are well known as among the foremost men of their several de- 
partments ; and their names form a ready guarantee for the high 
character of the books. Subjoined is a list of those manuals 
that have already appeared, with a short account of each. Others 
are in active preparation; and the whole will constitute a 
standard series specially adapted to the requirements of beginners, 
whether for private study or for school instruction. 
ASTRONOMY.—By the Astronomer 
ROYVAL.—POPULAR ASTRONOMY. With Illustrations. By G. B. 
AIRY, Astronomer Royal. Sixth and cheaper Edition. 18mo. cloth. 45. 62. 
This work consists of six lectures, which are intended ‘to explain to in- 
telligent persons the principles on which the instruments of an Observatory 
are constructed (omitting all details, so faras they are merely subsidiary), 
and the principles on which the observations made with these instruments are 
treated for deduction of the distances and weights of the bodies of the Solar 
System, and of a few stars, omitting all minutiz of formulz, and all trouble- 
some details of calculation.” ‘The speciality of this volume is the direct 
reference of every step to the Observatory, and the full description of the 
methods and instruments of observation. 
ASTRONOMY.—Mr. LOCKYER’S ELE- 
MENTARY LESSONS in ASTRONOMY. With Coloured Diagram of 
the Spectra of the Sun, Stars, and Nebulz, and numerous Illustrations. By 
J. NORMAN LOCKYER, F.R.S. Fifth Thousand. x18mo. 5s. 6d. 
The author has here aimed to give a connected view of the whole subject, 
and to supply facts, and ideas founded on the facts, to serve as a basis for 
subsequent study and discussion. The chapters treat of the Stars and 
Nebulz: the Sun the Solar System ; Apparent Movements of the Heavenly 
Bodies ; the Measurement of Time ; Light; the Telescope and Spectroscope ; 
Apparent Places of the Heavenly Bodies; the Real Distances and Dimen- 
sions; Universal Gravitation. The most recent astronomical discoveries 
are incorporated. 
QUESTIONS ON LOCKYER’S ELE- 
MENTARY LESSONS IN ASTRONOMY FOR SCHOOLS. By J. 
FORBES-ROBERTSON. 18mo. ts. 6d. 
PHYSIOLOGY.—Professor HUXLEY’S 
LESSONS in ELEMENTARY PHYSIOLOGY. With numerous Illus- 
trations. By T. H. HUXLEY, F-.R.S., Professor of Natural History in the 
Royal School of Mines. Twelfth Thousand. 18mo. cloth. 4s. 6d. 
This book describes and explains, in a series of graduated lessons, the 
principles of Human Physiology; or the Structure and Functions of the 
Human Body. The first lesson supplies a general view of the subject. 
This is followed by sections on the Vascular or Veinous System, and the 
Circulation ; the Blood andthe Lymph; Respiration ; Sources of Loss and of 
Gain to the Blood; the Function of Alimentation : Motion and Locomotion ; 
Sensations and Sensory Organs ; the Organ of Sight; the Coalescence of 
Sensations with one another and with other States of Consciousness ; the 
Nervous System and Innervation ; Histology, or the Minute Structure of the 
Tissues. A Table of Anatomical and Physiological Constants is appended. 
QUESTIONS ON HUXLEY’S PHYSIO- 
LOGY FOR SCHOOLS. By T. ALCOCK, M.D. x8mo. 1s. 6d. 
BOTANY. — PROFESSOR OLIVER’S 
LESSONS IN ELEMENTARY BOTANY. With nearly Two Hundred 
Illustrations. By DANIEL OLIVER, F-R-S., F.L.S. Seventh Thousand. 
18mo. cloth. 45. 6d. 
This book is designed to teach the Elements of Botany on Professor 
Henslow’s plan of selected Types and by the use of Schedules. The earlier 
chapters, embracing the Elements of Structural and Physiolo gical Botany, 
introduce us to the methodical study of the Original Types. The con- 
cluding chapters are entitled, ‘‘ How to Dry Plants,” and ** How to describe 
Plants.” <A valuable Glossary is appended to the volume. In the prepara- 
tion of this work free use has been made of the manuscript materials of the 
‘Jate PROFESSOR HENSLOW. 
ROSCOE’S 
CHEMISTRY. — Professor 
“LESSONS IN ELEMENTARY CHEMISTRY, INORGANIC AND 
ORGANIC. By HENRY ROSCOE, F-.R-S., Professor of Chemistry in 
Owens College, Manchester. With Numerous Illustrations and Chromo- 
Litho. of the Solar Spectrum, and of the Alkalies and Alkaline Earths. 
‘New Edition. Twenty-first Thousand. 18mo. cloth. 4s. 6d. 
It has been the endeavour of the author to arrange the most important 
facts and principles of Modern Chemistry in a plain but concise and scientific 
form, suited to the present requirements of elementary instruction. For the 
purpose of facilitating the attainment of exactitude in the knowledge of the 
subject, a series of exercises and questions upon the lessons have been added. 
The metric system of weights and measures, and the centigrade thermo- 
metric scale, are used throughout the work. The new edition, besides new 
woodcuts, contains many additions and improvements, and includes the 
most important of the latest discoveries. 
Second Edition, with the most recent Discoveries and Additional 
Illustrations, 
PROFESSOR ROSCOE’S “SPECTRUM 
ANALYSIS.” Lectures delivered in 1868. With Appendices, Chromo-litho- 
graphs, Maps, and upwards of 7o Illustrations. Medium 8vo, 21s. Second 
Edition. [Nearly ready. 
Westminster Review.— The lectures themselves furnish a most admir- 
able elementary treatise on the subject, whilst by the insertion in appendices 
to cach lecture of extracts from the most important published memoirs, the 
author has rendered it equally valuable as a text-book for advanced stu- 
dents.

TION. By C. H.H. CHEYNE, M.A. Crown 8vo. 3s. 6d.
