nn?ORT OV T>R. "P AUh (Ohomlet of J.ondnn. Endland. )
Ae the result, of. my. .obeervat Ion of the -working of
the process itself, I am of opinion It is completely
efficacious, and. so simple, -easy and expeditiouathat It'
promises to be or considerable value as an improvement in
tho manufacture of white load on the large 'scale. The oon~. ,
verslon lnto white lead takas place within the space of an,
hour (but safely within as many hours as tho Dutoh process '
takes months.) In addition to this rapidity of production,
the appliances required for the purpose are very simple end
inexpunnive ae compared with those now in use. ;i<'.
Though many attempts have been made to produce white
lead without incurring tho difficulties attending-the carry
ing out of what Is known as the Hutch process, none -of these
have h.therto succeeded In producing a material in .all > . j~
respects equal to the white lead made by that moro todioua
and more expansive process. It is therefore a point of
--
great importance in regard to tho Orr. process that the white
lead made by sane, not only bears comparison with the beat
kind made by the "Dutch process but i-s in -several part lou-
lore -superior to that.
..
It B.'ipsura to me thorefora that this method of
larking ".'bite lead is a docidod ndvanoo upon previous ex
perience and that it presents every indication of bocanlng
a stioeesrful process on tho manufacturing scale.
