PHOTOGRAPHICAL SECTION. 
January 10th, 1867. 
Dr. J. P. Joule, F.B.S., &c., Vice-President of the Section, 
in the Chair. 
Mr. Coote exhibited a selection from the series of photo- 
graphs by Braun, of Paris, consisting of copies of drawings 
by the old Masters, from the originals in the Louvre. Mr. 
Coote explained the method by which they were supposed

there could be no doubt that one of the processes suggested 
by Sir John Herschel about the year 1840, or some modifi-

method proposed by Mr. Gatty would also produce similar 
results. The prints are remarkable for their perfect resem-

artists and for use in schools of design, are quite equal to 
the originals. Of their permanence there cannot be the 
least doubt. 
The following letters from Mr. J. B. Dancer, F.RA.S., 
addressed to the Chairman, were then read by the Secre- 
tary : —
