NOTES ON THE RHINELAND CHEMICAL WORKS. 
industries concerned with the supply of the materials, whether for 
power, plant, or process, which it demands. ‘This all-round advance of 
attached industries is in the greatest measure due to the utilization of 
applied science, and particularly chemistry, in all branches of their 
work. 
The preparation of metals having special resisting or other proper- 
ties would be impossible without the chemist, and the beautiful earthen- 
ware and enamelled apparatus which is to be seen in general use has 
been produced largely with his assistance: 
It would appear that the standardizing of such apparatus as auto- 
claves, whether of plain metal or lined with enamel, of earthenware 
pots, tubes, and the like, greatly facilitates the work of plant erection, 
since it only requires a knowledge of the quantity of material to be 
handled in an operation to determine at once from a manufacturer’s 
list what vessels and appliances have to be ordered, and usually they 
can be obtained from stock. Large stocks of such equipment as auto- 
claves, open and closed pans, with and without stirring gear, tiles for 
lining, town packings, and glass fittings are carried in the large fac- 
tories, ‘and it is an education in itself to walk through a storage yard in 
which such materials are contained. 
There is no question that in this matter we have yet much to learn,’ 
and it may be hoped that, with the increasing demand for such materials 
in this country, we shall rapidly acquire the knowledge and technique: 
which provide the German chemical manufacturer with such a wide 
range of excellent plant materials. 
It was, of course, open to British manufacturers to obtain such sup- 
plies. from Germany in pre-war times, and it cannot therefore be said 
that lack of them prevented the maintenance of organic chemical in- 
dustry in this country, but that we were handicapped by the absence of 
such supplies at our own doors there can be no doubt, and we shall cer- 
tainly be better able to meet competition when such a supply is forth- 
coming from British makers. reat 
“My success as a man of science, whatever this may have amounted 
to, has been determined, as far as I can judge, by complex and diversified 
mental qualities and conditions. Of these, the most important have 
been—the love of science, unbounded patience in long reflecting over 
any subject, industry in observing and collecting facts, and a fair share. 
of invention as well as of common sense. With such moderate abilities 
as I possess, it is truly surprising that I should have influenced to a 
considerable extent the belief of scientific men on some points.”
