QUERY. 



Can any reader of Science 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 Lght 

 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.' 



Au 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 our mode of treating Neuras- 

 thenia, consequent 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.
