Our examination of the sample of beer taken before it
was run into the tank, and also the sample after it had been
in the tank 24 hours is not yet completed, and our report
on these will be submitted later.
We are,
Yours faithfully,

N.B.—In these cases the beer had been roused before samples
were taken, in the others the samples were drawn in the ordinary
way.
It will thus be seen that the percentage of lead varies somewhat
in various batches of tanks. The firm who supplied the
tanks, faced with the analyses, alternatively deny liability as they
stated that they did not understand that the tanks were to be
used for beer. I was shown a copy of an order from Messrs.
Hopkins to the firm in question in which it specifically states for
what purpose they were to be used. This defence, therefore,
would seem to carry no weight.
The Brewery Company and the Medical Officer of Health for
Hammersmith report that they have had no trouble with their
Hammersmith Houses in which the first batch of tanks were
installed.
In order to ascertain if there was any alteration in the trade
which might show whether there was any trouble in the firm's
other houses, especially in those four in the Hammersmith area
where the iron tanks were installed, I got the Brewery Company
to supply me with a certified copy of the deliveries to all their
houses in those districts and in our own. Analysis of these
showed that whereas there had been a definite diminution in the
roild ale trade in tho houses in our district with the iron tanks
this was not so in the other districts. It revealed the fact,
however, that the daily actual consumption in the houses in our
district was, as a mle, less per house than in the larger houses
