ed on the work. It will be
remembered that the detail and mass of this work are purely numerical;
every numerical coefficient being accompanied with a symbolical
correction whose value will sometimes depend on the time, but in every
case is ultimately to be obtained in a numerical form. Of these
coefficients, extracted (for convenience) from Delaunay's results,
there are 100 for parallax, 182 for longitude, 142 for latitude; the
arguments being preserved in the usual form."--After reviewing the
changes that had taken place at the Observatory during the past forty
years, the Report to the Board of Visitors concludes thus: "I much
desire to see the system of time-signals extended, by clocks or daily
signals, to various parts of our great cities and our dockyards, and
above all by hourly signals on the Start Point, which I believe would
be the greatest of all benefits to nautical chronometry. Should any
extension of our scientific work ever be contemplated, I would remark
that the Observatory is not the place for new physical investigations.
It is well adapted for following out any which, originating
with private investigators, have been reduced to laws susceptible
of verification by daily observation. The National Observatory
will, I trust, always remain on the site where it was first
planted, and which early acquired the name of 'Flamsteed Hill.'
There are some inconveniences in the position, arising principally
from the limited extent of the hill, but they are, in my opinion, very
far overbalanced by its advantages."--In a letter on the subject of
the Smith's Prizes Examination at Cambridge, which was always a matter
of the greatest interest to him, Airy renewed his objections to the
preponderance in the Papers of a class of Pure Mathematics, which he
considered was never likely under any circumstances to give the
slightest assistance to Physics. And, as before, these remarks called
forth a rejoinder from Prof. Cayley, who was responsible for many of
the questions of the class referred to.--In this year Airy completed
his "Notes on the Earlier Hebrew Scriptures," which were shortly
afterwards published as a book by Messrs Longmans, Green, & Co. In his
letter to the publishers introducing the subject, he says, "For many
years past I have at times put together a few sentences explanatory as
I conceive of the geographical and historical circumstances connected
with the principal events recorded in the Hebrew Scriptures. The
