ASTRONOMY WITH AN OPERA-GLASS. 
*jL A Popular Introduction to the Study of the Starry Heavens 
with the Simplest of Optical Instruments. By GARRETT P. 
SERVISS. 8vo. Cloth, $1.50. 
This is a unique book, quite alone in the field that it occupies. The call for a 
fourth edition within two years after its first publication attests its popularity. As one 
of its reviewers has said, "It is the most human book on the subject of the stars." 
It would have supplied Thomas Carlyle's want when he wrote, "Why did not some- 
body teach me the stars and make me at home in the starry heavens?" Interest in 
the geography of the heavens is increasing every year, as the discoveries of astrono- 
mers with the giant telescopes of our day push back the limits of the known univer&e, 
and this book is to those who read of such discoveries like an atlas to the student of 
history. 
Some of the compliments that the book has received are these: 
" A most interesting and even fascinating book." Christian Union. 
" The glimpses he allows to be seen of far-stretching vistas opening out on every 
side of his modest course of observation help to fix the attention of the negligent, and 
lighten the toil of the painstaking student. . . . Mr. Serviss writes with freshness and 
vivacity." London Saturday Review. 
" We are glad to welcome this, the second edition, of a popular introduction to the 
study of the heavens. . . . There could hardly be a more pleasant road to astro- 
nomical knowledge than it affords. ... A child may understand the text, which reads 
more like a collection of anecdotes than anything else, but this does not mar its sci- 
entific value." Nature. 
" Mr. Garrett P. Serviss's book, ' Astronomy with an Opera-Glass,' offers us an 
admirable hand-book and guide in the cultivation of this noble aesthetic discipline (the 
study of the stars)." New York Hotne Journal. 
"The book should belong to every family library." Boston Plome Journal. 
' This book ought to make star-gazing popular." New York Herald. 
"The author attributes much of the indifference of otherwise well-informed per- 
sons regarding the wonders of the starry firmament to the fact that telescopes are avail- 
able to few, and that most people have no idea of the possibilities of the more familiar 
instrument of almost daily use whose powers he sets forth." New Orleans Times- 
Democrat. 
" By its aid thousands of people who have resigned themselves to the ignorance in 
which they were left at school, by our wretched system of teaching by the book only, 
will thank Mr. Serviss for the suggestions he has so well canied out." New Yotk 
Times. 
" For amateur use this book is easily the best treatise on astronomy yet published " 
Chicago Herald. 
" 'Astronomy with an Opera-Glass ' fills a long-felt want." Albany Journal. 
"No intelligent reader of this book but will feel that if the author fails to set his 
public star-gazing the fault is not his, for his style is as winning, as graphic, and as 
clear as the delightful type in which it is printed." Providence Journal. 
" Mr. Serviss neither talks over the heads of his readers nor ignores the sublime 
complexity and range of his themes, but unites simplicity with scholarship, scientific 
precision with life -long enthusiasm, and a genuine eloquence with rate touches of hu- 
mor. Considered as a product of the publishing industry, the book is elegance itself."
