 osition was referred to a committee consisting of Messrs. C. F.

Mr. Edmund Quincy proposed the insertion of a clause in

Mr. S. P. Sharpies read a paper on some methods of dispos-

Professor Joseph Lovering communicated the results of the 

 computations made, under his direction, for the determination 

 of the difference of longitude between Cambridge and Duxbury, 

 Massachusetts, by means of telegraphic signals, and also for 

 the determination of the difference of transatlantic longitude 

 between Duxbury and Brest, France, by means of telegraphic 

 signals exchanged through the French cable-line. He stated 

 that three campaigns had already been conducted by the officers 

 of the United States Coast Survey for the settlement of trans- 

 atlantic longitudes. 1. The first was in the autumn of 1866, 

 when the signals were sent through the English cable-line. 

 2. The second was in the winter of 1869-70. 3. The third 

 was in the summer of 1872. In the second and third opera- 

 tions, the French cable-line was used. The communication of 

 Professor Lovering related especially to the second of these 

 campaigns, and was made by permission of Professor Benjamin 

 Peirce, the Superintendent of the United States Coast Survey. 

 A full account of the method of exchanging signals and the 

 forms of computation will appear in Volume IX. of the Memoirs
