In 1837 a _Botanical-Lexicon_ was published
by an author who described himself as
``The Rev. Patrick Keith, Clerk, F.L.S.''
This somewhat pedantic form deceived a
foreign cataloguer, who took Clerk for the
surname, and contracted ``Patrick Keith''
into the initials P.K. More inexcusable
was the blunder of an American who, in
describing J. E. H. Gordon's work on
_Electricity_, changed the author's degree
into the initials of a collaborator, one
Cantab. The joint authors were stated
to be J. E. H. Gordon and B. A. Cantab.

Chancellor of the Exchequer, of course
Isaac's son Benjamin, afterwards Prime
Minister and Earl of Beaconsfield; but
