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 manrals 
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 Astronomnter 
ROYAL.—POPULAR ASTRONOMY: With Illustrations. 
AIRY, Astronomer Royal. Sixth and cheaper Edition, 18mo, cloth. 4s. 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 far as 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 minutize 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 Nebulez, and numerous Illustrations. By 
J. NORMAN LOCKYER, F.R.S. Fourth Thousand. 18mo. 5s. 62. 
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 asa 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. Mr. Lockyer’s work supplements that of the Astronomer 
Royal mentioned in the previous article. 
PHYSIOLOGY.—Professor HUXLEY’S 
LESSONS in ELEMENTARY PHYSIOLOGY. With numerous Illus- 
trations. By T. H.HUXLEY, I.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 h States of Consciousness ; the 
Nervous System and Innervation ; Histol 
Tissues. A Table of Anatomical and Phy 1 Constants is appended 
The lessons are fully illustrated by numerous engravings. The manual is 
primarily intended to serve as a text-book for teachers and learners in boys’ 
and girls’ schools. 
QUESTIONS ON HUXLEYW’S PHYSIO- 
LOGY FOR SCHOOLS. By T. ALCOCK, M.D. 18mo. 1s. 6d. 
These Questions were drawn up as aids td the instruction of a class of 
young people in Physiology. 
BOTANY. — PROFESSOR OLIVER’S 
LESSONS IN ELEMENTARY BOTANY. With nearly Two Hundred 
Illustrations. By DANIEL OLIVER, I’.R-S., F.L.S. Seventh Thousand. 
18mo. cloth. 4s. 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 Physiological 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 
late PROFESSOR HENSLOW. 
CHEMISTRY. — Professor ROSCOE’S 
LESSONS IN ELEMENTARY CHEMISTRY, INORGANIC AND 
ORGANIC. By HENRY ROSCOE, F.RS., 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. 45. 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 
snbject, 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 improvements, and includes the 
most important of the latest discoveries.

ON THE ALGEBRAICAL AND 
NUMERICAL THEORY OF ERRORS OF OBSERVATIONS AND 
THE COMBINATION OF OBSERVATIONS. Crown S8yo. cloth. 
és. Gd. 
In order to spare astronomers and observers in natural philosophy the 
confusion and loss of time which are producel by referring to the ordinary 
treatises embracing éa// branches of probabilities (the first relating to 
chances which can be altered only by the changes of entire units or in- 
tegral multiples cf units in the fundameatal conditions of the problem ; 
the other concerning those chances which have respect to insensible 
gradations in the value of the element measures) the present tract has been 
drawn up. 
UNDULATORY THEORY OF OPTICS. 
Designed for the Use of Students in the University. New Edition. Crown 
8vo. cloth. 6s. 6d. 
The plan of this tract has been to include those phenomena only which 
admit of calculation, and the investigations are applied only to phenomena 
which actually have been observed. 
ON SOUND AND ATMOSPHERIC 
VIBRATIONS. With the Mathematical Elements of Music.—Designed 
for the Use of Students of the University. Crown Svo. 9s. 
By HUGH GODFRAY, M.A. 
A TREATISE ON ASTRONOMY, for 
the Use of Colleges and Schools. By HUGH GODFRAY, M.A., Mathe- 
matical Lecturer at Pembroke College, Cambridge. S8vo. cloth. 12s. 6d. 
This book embraces all those branches of Astronomy which have, from 
time to time, been recommended by the Cambridge Board of Mathematical 
Studies: but by far the larger and easier portion, adapted to the first three 
days of the Examination for Honours, may be read by the more advanced 
pupils in many of our schools. The author's aim has been to convey clear 
and distinct ideas of the celestial phenomena. 
AN ELEMENTARY TREATISE ON 
THE LUNAR THEORY, with a Prief Sketch of the Problem up to the 
time of Newton. By HUGH GODI’RAY, M.A. Second Edition, revised.

ANALYSIS.” Lectures delivered in 1868. With Appendices, Chromo-litho- 
graphs, Maps, and upwards of 70 Illustrations.. Medium 8vo. 21s. 
Westutinster Review.— Vhe 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 memeirs, the 
author has rendered it equally valuable as a text-book for advanced stu- 
dents.”

Planetary theory, which, being elementary in character, should be so far 
complete, as to contain all that is usually required by students in the Univer- 
sity of Cambridge. 
THE EARTH’S MOTION OF ROTA- 
TION. By C. H. H. CHEYNE, M.A. Crown 8vo. 3s. 6d.
