QUERY. 
Can any reader of Sczence cite 
a case of lightning stroke in 
which the dissipation of a small 
conductor (one-sixteenth of an 
inch in diameter, say, ) has failed 
to protect between two horizon- 
tal planes passing through its 
upper and lower ends respective- 
ly? »Plenty of cases have been 
found which show that when the 
conductor is dissipated the build- 
ing is not injured to the extent 
explained (for many of these see 
volumes of Philosophical Trans- 
actions at the time when light- 
ning was attracting the attention 
of the Royal Society), but not 
an exception is yet known, al 
though this query has been pub- 
lished far and wide among elec- 
tricians.

RACES AND PEOPLES. 
By DANIEL G, BRINTON, M.D. 
“The book is good, thoroughly good, and will long 
remain the best accessible elementary ethnography 
in our language.”—The Christian Union. 
“We strongly recommend Dr. Brinton’s ‘ Races 
and Peoples’ to both beginners and scholars. We 
are not aware of any other recent work on the 
science of which it treats in the English language.” 
—Asiatic Quarterly. 
“His book is an excellent one, and we can heartily 
recommend it as an introductory manual of ethnol- 
ogy.” —The Monist. 
“A useful and really interesting work, which de- 
serves to be widely read and studied both in Europe 
and America.”—Brighton (Eng.) Herald. 
“This volume is most stimulating. It is written 
with great clearness, so that anybody can under- 
stand, and while in some ways, perforce, superficial, 
grasps very well the complete field of humanity.”— 
The New York Times. 
“Dr, Brinton invests his scientific illustrations and 
measurements with an indescribable charm of nar- 
ration, so that ‘Races and Peoples,’ avowedly 3 rec- 
ord of discovered facts, is in reality a strong stim- 
ulant to the imagination.”—Philadelphia Public 
Ledger. 
“The work is indispensable to the student who re- 
quires an intelligent guide to a course of ethno- 
graphic reading.” —Philadelphia Times. 
Price, postpaid, $1.75. 
THE AMERICAN RACK. 
By DANIEL G. BRINTON, M.D. 
“The book is one of unusual interest and value,"=— 
Inter Ocean. 
“‘ Dr. Daniel G. Brinton writes as the acknowledged 
authority of the subject.”—Philadelphia Press. 
“The work will be of genuine value to all who 
wish to know the substance of what has been found 
out about the indigenous Americans.”—Nature. 
“©A masterly discussion, and an example of the 
successful education of the powers of observation.” 
—Philadelphia Ledger.

FOSSIL RESINS. 
This book is the result of an attempt to 
collect the scattered notices of fossil resins, 
exclusive of those on amber. The work is of 
interest also on account of descriptions given 
of the insects found embedded in these long- 
preserved exudations from early vegetation.
