ABSTRACT OF PROCEEDINGS. XXXIX. 
alterations is in general employment at the present time. 
The details of the process as conducted at Rhodes near 
Sydney were given. The main improvements consisted in 
the corroded lead being manipulated in contact with water 
and finally with oil. The process is automatic from the 
time that the corroded buckles are taken from the stone- 
ware pots until the finished white lead in oil is obtained. 
Mr. H. J. SULLIVAN continued the lecture, describing the 
blending of the white tead with pigments, and explaining 
the research work necessary in a paint factory to maintain 
and improve the quality of the products. He detailed the 
methods used in standardising the chemical and physical 
properties of his firm’s products. 
The lecture was followed by a discussion, in which the 
following took part, Dr. J. B. CLELAND, Messrs. WM. POOLE, 
A.D. OLLE, J. A. YOUNG, FINLAY, NEIL, WATT, the Chair- 
man and the Hon. Sec. 
Mr. SEVIER invited the members to inspect the works of 
Messrs. Lewis Berger and Sons at Rhodes, and twenty-five 
accepted the invitation upon August 13th. 
Dr. R. K. MURPHY contributed a note upon Cobalt Plat- 
ing which of recent years had been suggested as a substi- 
tute for nickel plating, The advantages are that iron, 
steel, and brass can be plated directly and more rapidly 
than with nickel, the material to be plated does not require 
the same careful preparation, and the finished surface is 
harder and does not scratch so easily. The present price 
for cobalt in Australia, however, would prohibit its general 
use, but if a demand should arise, the price would probably 
fall sufficiently to enable it to compete with nickel.
