Composition of Paints. The following table gives data 

 regarding the composition, etc., of paints applied to the steel 

 panels. 



Results of Inspection. The results of an inspection of the 

 steel test plates, made by Sub-committee D representing Com- 

 mittee D-l of the American Society for Testing Materials, is 

 herewith presented: 



" On Wednesday, June 28, 1911, the second inspection of the 

 Atlantic City Steel Test Panels, erected in October, 1908, was 

 made by Sub-committee D of Committee D-l, this Committee 

 having agreed to report upon the condition of the painted sur- 

 faces, leaving any report on the comparative corrosion of the

" According to the amount of rust apparent on the painted 

 surfaces of the panels, as well as the degree of checking, chalking, 

 scaling, cracking, peeling, loss of color, and other signs of paint 

 failure shown, ratings were given each panel. The system of
