'There is no doubt that in severe cases, and especially in acute rheumatism, the constant inhalation of strong radium emanation with oxygen to saturation of the system is of the greatest value; and no apparatus has given such excellent results as that which is shown here – the joint invention of Pro. Paul Zazarus and Dr. Saubermann. This apparatus is most useful when it is desired to highly charge the blood with radium emanation in order that it may exert its bactericidal power.'
