It is under this provision that, as the respondent contends, the
bill of sale given by the bankrupt requires due registration as to
after-acquired as well as then existing property ; without which
process he says it is void as against him. He contends that the
term "bill of sale," as there used, includes assignments of after-
acquired property ; that the definition in sec. 8 does not apply to
it because that section does not purport to enumerate all the
instruments that may be regarded as bills of sale. Sees. 5, 6, 7,
8 and 10 (4) of the Bills of Sale Act 1898 are re-enactments
upon repeal of secs. 31, 32, 33 and 34 of the Bankruptcy Acts
Amendment Act 1896. The respondent's contention that the
definition does not apply is, so far as we understand it, based on
the fact that in the last-mentioned Act sec. 1 provided that it
should with the Bankruptey Acts of 1887 and 1888 be cited
together and construed as one Act; which shows, he says, that
the above-named sections of the Bankruptcy Act of 1896 are not
to be read with the Bills of Sale Acts. These sections stood by
themselves in the Act of 1896, and there is nothing in the Bank-
ruptey Acts which affects the ordinary meaning of their terms.
We see no reason why the term "bill of sale" in sec. 31 of the
Bankruptcy Act of 1896 should not always have been read in that
section as an expression which had already acquired a meaning
similar to that given to it by the original Bills of Sale Act, and
which is exactly the meaning given to it by the consolidating Act
of which it is now a part. Ever since 1856 there was only one
sense in which lawyers and the public here had understovud the
expression "bill of sale," and that is the sense in which the English
Act of 1854 and 19 Vict. No. 2 had alike used it. But if this
were not so, we are thrown back upon the meaning of the term
as used before this Statute of 1854 - that is, the common law
meaning. Then, what was the meaning of a bill of sale at com-
mon law? It seems to us that it meant nothing more than an
assignment of personal chattels in existence, and therefore assign-
able at common law. It might be secret or open; it might be
accompanied or followed by a change of possession, These were
