Magnetism and Electricity. By Professor F. Guthrie. New edition, 
revised by Mr. C. Y. Boys ; 428 pp., 328 illustrations. Published 
by W. Collins and Sons ; price 3s. 6d. 
The lai’ge circulation of Professor Guthrie’s book—it has now reached 
its twentieth thousand—is the natural result of the high merit of the 
book and its low price. To the present edition Mr. Boys has added a 
valuable chapter dealing with electrical measurements and with the 
wonderful discoveries which have rendered the last few years famous 
in the history of electricity. 
The Student's Elements of Geology. By Sir C. Lyell. Fourth edition, 
edited by Professor P. M. Duncan. 621 pp., 8vo.; 636 woodcuts; 
price 9s. Published by 0. Murray. 
Students will hail with pleasure the appearance of a new edition of 
“ Lyell’s Elements,” a standard work which has been out of print for 
several years. It has been revised with great care by Prof. Duncan, 
who has incorporated with the book the most recent geological 
discoveries, including even Prof. Geikie’s acknowledgment of the true 
arrangement of the rocks of the Highlands, a statement only published 
a few weeks ago. The illustrations, which are very numerous, appear 
to have been re-drawn, as they are as fresh as those of the first edition. 
The Table of British Fossils given in the appendix, which extends 
over twenty-two pages, and shows at a glance the successive appear¬ 
ance and development in time of the chief orders, classes, or families 
of animals and plants, is a valuable feature. There can be no doubt 
but that this book still remains the best general text-book of geology— 
considering its fullness of detail, the fact that it is contained in one 
volume, and ibs moderate price. W. J. H. 
METEOROLOGICAL NOTES.— December, 1884. 
The barometer was unsteady throughout the month—fluctuating 
between 29*1 inches and 30*1 inches until the 20tli, when it fell to 
28*857 inches, and rose in forty-eight hours to 30*311 inches, remaining 
high during the remainder of the month. Temperature was about 
the mean, and was variable in the earlier part of the month. The 
highest maxima were 57*7° at Hodsock, on the 13th ; 54*2° at Lough¬ 
borough, 54*0° at Henley-in-Arden, and 53*3° at Coston Rectory, on 
the 6tli; and 52*8° at Strelley, on the 13th. In the rays of the sun 
84*2° was registered at Hodsock, on the 13th; 76*9° at Loughborough, 
on the 5tli; and 72*3° at Strelley, on the 7th. The lowest minima 
occurred on the 31st, and were 22*0° at Coston Rectory, 23*3° at 
Hodsock, 24.0° at Henley-in-Arden, 24*6° at Loughborough, and 25*6° 
at Strelley. On the same date the thermometer on the grass recorded 
18.7° at Strelley, 19*4° at Hodsock, and 21*7 at Loughborough. The 
rainfall was below the average, and consisted of small amounts. The 
12th and 15tli were the only days before the 21st on which there was
