ARABIAN WispoM. Selections translated by 
John Wortabet, M.D. New York: E. 
P. Dutton & Co. Cloth; 16mo.; 75 pages. 
Price, 40 cents net. 
The Arabic language is particularly rich 
in wise sayings and proverbs, and Dr. 
Wortabet has compiled from Oriental 
sources an excellent little handbook to serve 
as an introduction to an appreciation of 
the little-known wealth of material in 
Arabic literature. One could not choose a 
better guide. 
THE RELIGION OF THE Koran. By Arthur 
N. Wollaston, K.C.1.E. New York: E. 
P:. Dutton & ‘Go, (Cloth; W6mo;s 70 
pages. Price, 40 cents net. 
As the sacred volume of some one hun- 
dred and seventy millions of the present- 
day inhabitants of the world, the Koran 
possesses an interest and importance that 
well merits, and will amply repay, atten- 
tion and study. The admirably translated, 
well arranged and carefully selected ex- 
tracts from the Koran contained in this lit- 
tle volume commends it to student and lay- 
man alike. 
THE TEACHINGS OF ZOROASTER. By S. A. 
Kapadia, M.D. New York: E. P. Dut- 
ton & Co., 1911. Cloth; 16mo.; 104 
pages. Price, 60 cents net. 
The ancient precepts of the Persian 
prophet of the Parsis are clearly set forth 
in “The Teachings of Zoroaster,’ by Dr. 
Kapadia, who is an authority of the Parsi 
religion, and whose little book is one of 
the most interesting of the later volumes in 
“The Wisdom of the East Series,” and will 
introduce the Western reader to a prepara- 
tory knowledge of the tenets of the great 
Persian moralist who lived and preached 
some 3,500 years ago. 
Tue WIspoM OF THE ApocrypHA. New 
York: E. P. Dutton & Co. Cloth; 16mo. ; 
124 pages. Price, 60 cents net. 
The selection of the two Apocryphal 
books of the Old Testament—The Wisdom 
of Solomon and Ecclesiasticus—which ap- 
pear in this little volume accompanied by 
an introduction from the pen of C. E. Law- 
rence, has been made by the editors of “The 
Wisdom of the East Series,’ as present- 
ing human documents reflecting the ideals 
and the philosophly of eastern wisdom. 
From this point of view there can be no 
question of the great interest and value of 
these books, not unworthy to be ranged, 
as literature, with ‘The Proverbs” and 
“Ecclesiastes, although not attaining equal- 
ity of excellence with these accepted parts 
of the Canon. As the wisdom-books re- 
printed in the present volume give helpful 
strengthening counsel on the great and the 
little troubles, fears, comforts, questions 
which—all in a tangle and somehow—com- 
prise human life, they should become less 
neglected than they are at present.

developments in the artistic construction in 
the decoration and furnishing of the house, 
It is planned to appeal to all who are in- 
terested in such matters. While the text is 
of no special importance, even meagre in 
August, 1912 
its data at times, the illustrations are ex- 
cellent and present a diversity of subject 
matters will worth careful attention. 
INHERITANCE OF ACQUIRED CHARACTERS. 
By Eugenio Rignano. Chicago: The 
Open Court Publishing Company: 1911. 
Cloth. 8vo. 413 pages. Price, $3 net. 
Professor Basil Harvey, the translator 
of this work, contributes to it a preface 
wherein he states that the author is a stu- 
dent of Biology who has also the training 
of an engineer and physicist. His attack on 
biological problems is from that side. In 
this book he offers an explanation on a 
physical basis of assimilation, cell division, 
and the biogenetic law of recapitulation in 
ontogeny, and he suggests a mechanism 
whereby the inheritance of acquired char- 
acters may be effected. This much dis- 
cussed but unsolved question excites the 
keenest interest and the present work is a 
valuable contribution to the subject, the re- 
sult of much original investigation. 
Farm Boys anp Grrts. By William A. 
McKeever. New York: Macmillan Com- 
pany. 1912. Cloth. 8vo. 326 pages. 
Price, $1.50 net. 
The reviewer heartily endorses the pur- 
pose of this excellent book, in the prepara- 
tion of which the author appears to have 
had in mind two classes of readers; namely, 
the rural parents and the many persons who 
are interested in carrying forward the rural 
work discussed in the several chapters on 
“Building a Good Life,” “The Time To 
3uild,’ “The Rural Home and Character 
Development,” “The Country Mother and 
the Children,” “Constructing the Country 
Dwelling,” “Juvenile Literature in the 
Farm Home,” “The Rural Church and the 
Young People,” “The Transformation of 
the Rural School,” “The Farmer and His 
Wife,” “How Much Work for the Coun- 
try Boy,” and others. This is one of the 
most helpful volumes that have appeared in 
Macmillan’s “Rural Science Series.” 
NorRTH WALSHAM AND THE NORFOLK 
Broaps. By Florence Bohun. Yelverton 
(South Devon). By Edward Francis, 
New York: Frederick Warne & Co., 
1911. 
These are two newly-issued “Homeland” 
guidebooks, abounding in fine illustration 
and graphic description and maintaining in 
every way the high standard which the pub- 
lishers have set themselves. Cheap in price 
and ephemeral as to concrete make-up, the 
little booklets may be tucked away in a poc- 
ket without compunction, yet are ever ready 
to yield up their exact knowledge and in- 
spiring information for the benefit of trav- 
eler or shut-in. History, topography and 
present-day features of interest are alike 
charmingly unfolded. 
THe Sayincs:-or Conructus. By Lionel 
Giles, M.A. New York: E. P. Dutton 
& Co, Cloth; 16mo.; 132 pages. Price, 
60 cents. 
This is a new and excellent translation 
of the greater part of the Confucian 
Analects. Confucius stands forth as one of 
the few supremely great figures in the 
world’s history, and yet how httle we have 
chosen to concern ourselves with arything 
about him beyond that fact. Professor 
Giles’ excellent volume will enable the 
reader who has been neglectful in the past 
to make amends conveniently and briefly, 
since this little book, though small in com- 
pass, is rich in presenting to us glimpses of 
the philosophy of the greatest figure in 
Chinese history and of the man, Confucius 
himself.
