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.

THE MODERN MALADY ; or, Suf- 
” ferers from ‘ Nerves,’ 
An introduction to public consideration, 
from a non-medical point of view, of a con- 
dition of ill-health which is increasingly 
prevalent in all ranks of society. In the 
first part of this work the author dwells on 
the errors in cur mode of treating Neuras- 
thenia, consequeut on the wide ignorance of 
the subject which still prevails: in the sec- 
ond part, attention is drawn to the principal 
causes of the malady. The allegory forming 
the Introduction to Part I. gives a brief his- 
tory of nervous exhaustion and the modes of 
treatment which have at various times been 
thought suitable to this most painful and try- 
ing disease.
