It was a splendid race, neither having any advantage for
a long way up, it being a neck and neck affair ; but ultimately
Cambridge drew slightly in advance, gradually improved
upon it, and won by a length and a-halt.

Oxford were slightly the favourites, but both parties seemed
extremely confident, as did their friends, and those unac-
quainted with either expressed their admiration at the fine
appearance of both crews.
The Oxonians were on the Berks shore. A beautiful start
at a few paces having been effected, the Cantabs pulled the
nose of their boat a trifle in front, and in this position and
oar and oar a most beautiful race VMS continued up to Re-
menham with undiminished pace. Oxford here gradually
began to shake their opponents off and continued to im-
prove their position, the Cantabs having broken a thwart,
owing to which the Oxonians acquired a greater lead than
before.

NASMYTH'S ABSOLUTE SAFETY VALVE.--Mr' Na:
smyth has forwarded to us a representation of the vane
already described by us in the current volume. The diagram
appears to bear out what is there said as to its peculiarity of
construction. It must be effectual in preventing the Talve
from getting set fast in its seat, unless, indeed, there be some
extraordinary power of attraction at work, electrical or mag-
netic, which even the violent agitation of the water in ebul-
lition cannot overcome. The valve, however, is spherical,
and one cannot readily conceive even a force of this kind to
be capable of rendering such a form of valve quite fixed and
immoveable. The precise nature of the cause of fixture, in
some cases at least, is by no means clear, and seems to re-
quire further and closer investigation; and if it should turn
out that electrical or magnetic action has something to do
with so dangerous an accident, it will be very easy to apply
the proper remedy so as to render such a valve as Mr.Na-
myth's, even in this assumed respect, quite certain in its
action. That electricity may have more to do with boiler
fiexplosion than might at first s'ightybdero.le
