M. Warlomont examined the blood and products of respiration chemically, and satisfied himself of their normal character, except that the former contained an excessive amount of white corpuscles. When being closely interrogated, Louise admitted that, though she did not sleep, she had short periods of forgetfulness at night.
Advice is therefore given to every person who has practised violent singing-exercises, which cause perspiration, immediately to change his clothing after having been rubbed down with a horsehair glove or with flannel sprinkled with alcohol.

At this time, an apparently rapid decline had become developed in the system of his wife, and on the night on which he had appealed to this person's feelings of humanity, as mentioned in the opening of the story, he found her, on his return, extremely ill. A high fever had set in, and she was suffering. much from difficult respiration.
The food products are stored in various parts of the plant for future use, or are expended immediately in the growth and movements of the plant. In order that they shall be used for growth, free oxygen is required, and this is supplied by the respiration of the plant. Some plants steal their food ready-made. Such a one is the Dodder, which sends its roots directly into the plant on which it feeds.
It has, therefore, long been known that carbonic acid gas is given off at night. The amount, however, is so small that it could not injure the air of the room, as is popularly supposed. Respiration takes place principally through the stomata of the leaves.
From these experiments," he says, "the upper surface of the leaf appeared to be the immediate organ of respiration, because the colored fluid was carried to the extremities of the leaf by vessels most conspicuous on the upper surface, and there changed into a milky fluid, which is the blood of the plant, and then returned by concomitant veins on the under surface, which were seen to ooze when divided with scissors, and which, in Picris, particularly, render the under surface of the leaves greatly whiter than the upper one."
Hence a gaseous interchange, the essential step in respiration, very readily takes place between the blood and the air, by which the latter gains moisture and carbon dioxid, and loses its oxygen. These changes in the lungs also restore to the dark blood its rosy tint.
These natural efforts were artificially aided as far as possible. At 5:45 P.M. natural respiration was fairly though insufficiently established, the skin began to lose its deadly hue, and titillation of the fauces caused weak reflex contractions.
It was a man between sixty and seventy; an age at which the heart can seldom stand very much shocking, or lowering, especially where the brain is diseased. So they placed him in a shower-bath, narrow enough to impede respiration, without the falling water, which of necessity drives out air. In short a vertical box with holes all round the top.
