 Medlicott were largely in arrears of subscription, and though registered 

 letters had been sent to them in accordance with Rule 37 no notice had 

 been taken of them. Their names would therefore be suspended for a 

 month as defaulters in the Society's meeting-room, and unless the sums 

 due were paid in the meantime they will be declared removed from the 

 Society at its next meeting. In accordance with Rule 38 this fact will 

 be notified in the Proceedings. 



Col. Waterhouse exhibited some views of Jaunpur and other speci- 

 mens of heliogravure by the photo-etching process and said : — 



" At the meeting of the Society in March 1887, I exhibited some 

 specimens of heliogravure, chiefly by the photo-electrotype method. 

 These I have now the pleasure of showing you are by the photo-etching 

 process, and are reproductions from the original negatives of some views 

 of Jaunpur intended for the illustration of Dr. Burgess' Archseological 

 Survey Report. My assistant, Mr. Turner, has carried out a good many 

 improvements in the process lately, and it is now being worked with 

 considerable success. We find that many of these reproductions are 

 really much better than ordinary silver prints from the same neo-atives 

 and this was particularly the case with some reductions we lately made 

 from Dr. Giles' negatives taken in Gilgit, The etching process is ex- 

 ceedingly rapid, the plates require very little touching up, and the 

 prints being pulled in the copper-plate press are as permanent as or- 

 dinary engravings. 



I gave a description of the process on the occasionj-eferred to and 

 need not repeat it, but I may remark that we have now adopted the plan 

 of etching with baths of perchloride of iron of different streno-ths, usu- 

 ally 45° 40° 36^ and 27° B. commencing with the strongest."
