THE POOR LAW BOARD AND THB HOLBORN
wrawoollnilt —An Lotiation oto the Dort of the
Poor Law Board hal loog Wen *rumen tor owning seen
the removal of all pauper children into establishments sepa-
rate sad distinct from workhouse, and with this elm they
hive ',Unwed a communicatim. to the Board of Guardians

of the Holborn Union, is which they call their attention to
the esteems disadvantsgtoueciteureetanees under which the
boys and girls are retained in the workhouse, and at the
sense time to the want of a male repast ward.
welch leads to paupers of this class being pissed
in the recovery ward, in violetion of the provisions of
article 99 of the general consolidated orders, and
tameable a hope that the guardians will Lie ao time in
adoptiag such measures as may be calculated to put the
workhouse on a bettor footing in these teepee% The
partlians are desirous of retsiping the children in the
workhouse, bat they are unable to comply with the Nugget-
dons*. the Poor Law Board, without the erection of addi-
tional buildings to the workhouse, and the plans for thew
Mr. L. IL haus, architect, has been directed to prepare.
bat the lessees of the premises edjoiaing the workhouse and
the trustees of Morton's Charity, who are the freeholders,
object to the erection of the proposed additional buildings,
ea the ground that they will obstreot the light and air tithe
inhabitants of the neighbourirg houses.
/lingers or Ovra•vrowt.—An interesting sobjrog
fat discussion was started by Dr. Theophilus Thompson, at
tlar tut meeting of the Medical Society of London, namely.
The Effects produced on the Blood by Mental Labour."
His view is that over-werk of the brain occasions deteriora-
tion of the blood sad be addaxes itieteace• in which sleep-
I eeeee se, and toes of mental power following over-eaertion,
were associated with jugular murmurs, and a remarkable
deficiency of the white corpuscles in the blood, then not
bring a fourth of the average myrmidon of health—ill this
without neuseular debility or impaired dietetic°, but with
oxeluria to a slight extent. Dr. Thompson thinks that the
wear and tear of inordinate and auntous week Gee as a ena-
ct, sloe of shocks through the nervous system ; and he
believes that sudden and violent shocks, as in railway col-
lisions, produce analogous results. He addaxes a remark-
able ease from the practice of Sir Henry Marsh, la which a
rang lady who had accidentally poierned ter lather died
with an entire eking' in the condition of the blood, without
any other organic disease. There is a wide field for farther
inve•tigatios here, for, as Dr. Thompson says, there is a
possibility of the hereditary tracrealtetos of the physical
condition iaduced by inordinate mental labour, and the
present tendency to over work the brain may prove un-
favourable to the production of great see.—Medieal Telma
