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 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. 



First inserted June 19. No response 

 to date.

TO THE READERS OF SCIENCE. 



PUBLISHER'S ANNOUNCEMENT. 



OUR PLANS. 



Within the past six months the use of Science by 

 scientific men and women as a medium for prompt 

 publication and weekly discussion, has increased 

 very materially, so that the pages are now well 

 filled each week with original matter. As the num- 

 ber of those promising contributions is increasing 

 at the rate of three or four each day. It cannot be 

 long before Science at Its present size will be too 

 small tor the amount of matter offered. We have 

 under consideration therefore an enlargement of 

 the paper by one-half, but must first learn the tem- 

 per of our constituency as to an advance in price to 

 S5.00, which was the subscription price from the 

 start for four years, up to June 30, 1887. Further, to 

 carry out the proposed enlai-gement, we shall need 

 five hundred additional subscribers. If you are not 

 already a subscriber, are you willing to aid In mak- 

 ing Science more worthy of American scientific work 

 by becoming one ? 



It goes without saying, that the demand tor scien- 

 tific literature is limited, when compared with that 

 for literature which is more to the public taste, so 

 that the receipts of most of the Scientific Journals, 

 in this country, do not pay quite for their printing 

 and paper, to say nothing of the other items of ex- 

 pense. We say this merely to emphasize the fact, 

 that generous and prompt support must be ac- 

 corded this iT.ove if it is to succeed.
