Note 3 — I. VENTILATION AND WARMING.

It is very desirable that the windows in a sick room should be such as that the patient shall, if he can move about, be able to open and shut them easily himself. In fact the sick room is very seldom kept aired if this is not the case—so very few people have any perception of what is a healthy atmosphere for the sick. The sick man often says, "This room where I spend 22 hours out of the 24 is fresher than the other where I only spend 2. Because here I can manage the windows myself." And [Transcriber's Note: Word, possibly "it" missing in original.] is true.
