II appears from official documents that during the

ffty departments OF France Upwards Of 232, 900
patients treated at home; they received 606 757
visits, besides 2S2 20 consultations. Tho sums col

and the expenses 10 31,0Cl francs. The average
cost OF every patients was 81. 3lc.
Glass panes, constantly exposed to the action Of

potash or soda they contain glass being nothing but

either lime or fitharge) combines with the carbooic
acid Of the air. A whtish opaqueness Is the consc-
pane return 70 its pristine transparency, It should
irst be rubbed with dilute hydrochloric acid and
then cleaned with moistened whitening. BY this
means glass in an extreme state Of decomposition
may be completely restored.
Mr.. Dancer has been examining the dust inthe

may account In great measure for the mysterious
way IN whicn some diseases propagate themselves,
for instance cholera. This disease Is spread In only
one way--by persons actually swallowing cholera
poison. Persons may inhale with fmpunity the
breath from Q patient In the last stage OF
this epidemic, hut the smallest atom Of the
poison received into the stomach will cause an at
tack Of the disease. We can understand, then, how
q small quantity OF choleraic excavations, drying
the door OF room, may afterwards float about In
the form OF dust and cause the death OF hundreds.
The most common method for destroying mtsas-

combination with lime; but when this Is not at hand
the fumes OF deutoxide Of nitrogen viii produce
similar effect. This is obtained by pouring little
nitric acid on hafpenny In saucer out as this gas
irritates the respiratory organs the experiment
should he performed IN n corner OF the room, and
care should be taken not TO inhale the emanaions.
