in number, which were the subject of the previous agreement,
should be divided between them upon certain terms and conditions,
The transaction from which this agreement arose began in May
1927. The respondent had acquired from one Forsyth an option
to buy, for the sum of £5,000, letters patent for the Commonwealth
of Australia for inventions relating to pulsators in milking machines,
and he himself was the owner of a patent relating to the same subject.
At the time when the respondent obtained the option a contract
subsisted between him and Forsyth, the substance of which was
that he should be employed to exploit the patents by disposing of
licences in Australia. He was bound to devote his whole time and
attention to doing so, except that he might accept employment from
any licensee. In consideration of devoting himself to this work
he would receive half the royalties obtained in respect of the patents.
Although the time limited for the exercise of the option actually
expired on 4th March 1927, Forsyth seems to have treated it as
extended. Shortly before or early in May 1927 the respondent
opened up negotiations with the appellant Company. He proposed
that Forsyth's interest should be acquired and that they should
jointly exploit the patents by forming a new company. The option
would be exercised and the patents would be transferred to the new
company which would find the money to pay the price to Forsyth.
Shares in the company were to be allotted, five thousand of £1 each
fully paid up to the respondent and five thousand to the appellant
Company. In making this proposal the respondent represented
that he was entitled to a half-interest in the patents, and that Forsyth
was entitled to the other half-interest, but was willing to sell it ata
price of £5,000. The whole property in the patents was valued at
£10,000. In support of this value the respondent gave £1,000 per
annum as an estimate of the revenue which might be produced from
royalties, and he says a capitalization on a ten-years' basis was
adopted on the part of the appellant. In point of fact, some of the
more important patents had more than ten years yet to expire,
although many of the patents would expire at much earlier dates.
Written notes of the proposals were placed before the appellant
Company, and finally an agreement was arrived at. On 10th May
1927 the appellant Company handed the respondent a letter stating
