diagnosis and aetiology of the plaintifi's disorder, a view which I
am unable to share; but it also depended to a very great extent
upon inferences drawn from the results of chemical analyses in
respect of the garments in question and other garments, from the
character of the processes to which the web of the ankle ends was
subjected in the course of the manufacture, and from other cireum-
stances. It appeared that, in November 1931, the defendant, the
manufacturer, submitted to an analytical chemist for report one of the
pairs of underpants which the plaintiff had returned to the retailer.
He reported that his examination disclosed the presence of no chemical
substance likely to cause irritation of the skin, but he also reported
that the mineral portion of the water soluble extract which he had
made consisted mainly of neutral sulphates. The percentage of such
matter was small, but was larger in the ankle and crutch of the
garment than in the waist and knee. In May 1932, the same chemist
made another examination, this time of all four garments and of a
fifth which was taken as a sample from stock. From each garment
he made up a given weight of material taken from various parts of
the garment. From each sample he extracted a solution using
distilled water at blood temperature. He reported that he obtained
a percentage by weight of sulphur dioxide as follows : in one pair of
the plaintiff's underpants, 0.0082 per cent, in the other, 0.0201
per cent, in one of the plaintifi's singlets none, in the other 0.0070
per cent, in the sample from stock, 0.0313 per cent. This statement
was not intended to mean that the fabric contained sulphur dioxide,
which is a gas, but that it was represented or obtainable. In fact
he considered that the sulphur dioxide represented a sulphite,
With these reports before them, the defendants answered an inter-
rogatory that the garments at the time of delivery to the retailer
by the manufacturer contained, among other things, sulphur dioxide.
The evidence given by the defendants of the process of manufacture
disclosed that the woven material, after going through a shrinking
process in which calcium hypochlorite and some hydrochlorie acid
are used, is put through a bath, containing bisulphite of soda, to
get rid of chlorine. The compounds formed are soluble, and in that
process and in three succeeding washing processes, they would be
completely taken out. The percentages of sulphur dioxide disclosed
