Dear Sir,
We received this morning by post, from Messrs. G.
Hopkins & Sons, (Clerkenwell), Ltd., a sample of enamel
which they certify to have been chipped from No. 8 tank.
The sample consisted of hard flakes of cream-coloured
enamel, most of which had black patches of adhering metal
on one side. We used for analysis flakes which were quite
free from these patches.
We find that the enamel contains 42.0 per cent, of lead.
Yours faithfully,
Eynon & Lane.
In order to close the door absolutely, I visited Messrs. Hopkins
and took a sample of enamel from one of the last tanks delivered,
which had never been set up, the number being 190 on the serial
delivery list.
Messrs. Hopkins submitted their samples of beer which had
been left in the tanks and also of the crystaline flakes and enamel
to Messrs. Heron & Son, the well-known analysis. Their report
is as follows:—
