OXLEY'S IMPEOVFID 
PORTABLE RUSSIAN VAPOUR STEAM BATH 
FOR HOME AND FAMILY USE. 
'PHIS BATH is offered to 
supply a long-felt deside- 
ratum, viz., an effedtive Steam 
Vapour Bath for Home Use. 
It combines simplicity with 
effectiveness, and can be used 
in any home, with a minimum 
of trouble. It is mounted on 
castors, and runs so easily that 
a child can move it from room 
to room. The superiority of 
Steam Vapour over Hot Air 
for Baths is incontestable, as 
it is quicker in its aftion, more 
searching to the skin, and does 
not produce the unpleasant las- 
situdeof the Turkish Bath. The 
head being exposed, enables the 
bather to breathe the atmos- 
phere at the usual temperature.
