a descriptive account, accompanied by -woodcuts, of tbe cave of Cro-magnon, 
and some general remarks by M. E. Lartet on tbe burial-place of the cave- 
dwellers of Perigord. The sections show how large a quantity of matter 
had accumulated in the cave, and how great must have been the difficulty 
of making the necessary excavations. M. Lartet describes a number of 
interesting relics and fossils found with the human remains. Among the 
former we may mention a curious necklace made of shells of the peri- 
winkle and whelk, a sort of amulet or pendant of ivory — oval, flat, and 
pierced with two holes. The presence of the remains of an enormous bear, 
of the mammoth, of the great cave-lion, and the reindeer, shows the 
great antiquity of the deposits. These and certain other facts lead M. 
Lartet to refer ^^this station of Cro-magnon to the age immediately 
preceding that artistic period which saw in this coimtry the flrst attempts 
of the engraver and sculptor.” Of the plates in this number, four are 
devoted to flint, bone, and other weapons, and one contains a full-size re- 
presentation of the necklace of shells and the amulet. Every new number 
of this work strengthens our conviction that, when completed, it will be the 
finest contribution to prehistoric archaeology in any language. 
POPULAE ASTEONOMY.* 
O F the two books which we have here classed together, the first is 
one of Messrs. Macmillan’s excellent scientific series, the second one of 
Mr. Hardwicke’s no less valuable handy-books. Both are addressed to 
beginners and amatem’s in astronomy j but Mr. Lockyer’s volume takes 
rather a higher, and of course a more systematic aim, than Mr. Proctor’s. 
Indeed, the differences between the two are these : the first is intended to 
be read by those who know nothing about the subject, and therefore embraces 
all that relates to the chief phenomena and the generalisations of the science ; 
the second offers itself to the student — amateur or professional — who has 
already mastered the elements of the subject, and wishes to make him- 
self practically conversant with the heavens. They are both admirable 
contributions to oui’ literature, but, while we should advise those interested 
in astronomy to possess the two, we should say, Study Mr. Lockyer’s book 
first, and then you can take up IVL. Proctor’s ‘ Half-hours ’ with the greatest 
advantage and the least difficulty.” As we should have expected, Mr. 
Lockyer has brought his book up to the latest advance in scientific research, 
and the spectroscope and chronograph are briefly but most intelligibly 
described. He is nothing if not clear, and though he carefully abstains 
from what is styled popularisation, we think that even to those unused to 
scientific reading this book presents no insurmountable difficulties. He deals 
with his subject in nine chapters, whose headings are shortly as follows : 
* Elementary Lessons in Astronomy.” By J. Norman Lockyer,

Half-hours with the Telescope.” By E. A. Proctor, B.A., F.E.A.S.
