deceive ' is not a phrase which has reference to to-day or when the
writ is issued. It means, according to the proper use of language,
calculated in the ordinary sense of business, assuming business will
be carried on in future not precisely and not exactly in the mode it
is carried on to-day by this new company, but with one's knowledge
of affairs how it is likely to be carried on." Applying these
observations to the present case, we have to disregard the get-up
of the respondents' goods. They may, if now successful, use the
name " Mulsol " alone, or at all events without any get-up distin-
guishing their wares from the get-up of the appellant Company.
And we have to bear in mind that get-up often plays a secondary
part, if any, in a matter of this kind. The tongue and the ear are
the chief channels of communication for the present purpose. The
least slur or want of precision in speaking, the least failure to hear
the exact pronunciation, and error is almost certain to arise.
Tn purchasing articles of this kind - it is not a question of a cup
~ of tea or a yard of calico, but of an urgent remedy for what may
be a serious illness - the Court ought, in my opinion, to be vigilant
to prevent confusion. Where, on a field of competition already
occupied, a new rival enters and, with the vast range of inventive
possibility open to him, selects an assumed name, there is a duty
on him to see that his invented designation does not destroy the
distinctiveness of his competitors' marks. The Court should, as I
view the matter, compel him to keep at such a distance from prior
existing trade marks, as to prevent both unfair encroachment on
competitors' trade, and unnecessary danger to the public. It may
be conceded that in the first instance the respondents happened,
however surprising it may appear, to get into a false position without
bad faith, and entirely through ignorance of circumstances which
ordinarily one would imagine were within the knowledge of those
engaged in the business of chemists and druggists. Nevertheless,
even conceding so much, that is by no means conclusive as to the
respondents' good faith in resisting this application. The material
facts are these : - The appellant Company, taking the first distinctive
word of its name, Mond, from the surname of a celebrated chemist,
