may submit them to the judgment of the distinguished physicists 
who will doubtless be there assembled. 
To such a judgment I pledge myself implicitly to bow; no one 
being better aware than myself of the disadvantage under which 
I labor in possessing no more than an elementary knowledge of 
physical doctrine.— Atheneum, May 13. 
2. Reclamation. — Letter to the Editors, from Mr. George 
Davidson, U. S. Coast Survey, dated San Francisco, March 7, 
1876.—In the March number of your Journal (No. 63, vol. xi,) 
Article xxix, by Professor Lovering, the statement is made that 
“the late Professor Winlock [in February and March, 1869] sent 
electrical signals from Cambridge to San Francisco, and thence 
by other lines to Canada, and back again to Cambridge, over a 
loop of wire measuring 7200 miles.” 
Professor Winlock and I were always in full accord in this and 
other matters, and I am sure he never made the above claim. O 
the contrary, he gave me full credit for the inception of the experi- 
\ sala and the successful determination of the wave time over a 
a : : ; 
Moreover, the experiment was not made at boars it was 
rancisco, 
? 
unfortunately the cable across the Golden Gate broke after passing 
the first series, and no more were undertaken. 
The whole work is fully detailed in the records of the Coast 
Survey, and, by permission of the Superintendent, the results and 
modus operandi were verbally communicated by me to the Cali- 
fornia Academy of Sciences. 
If, however, the details of my work and of Professor Winlock’s 
device are of any interest to experimentalists, I can readily supply 
em from the original memoranda.
