In putting him down to sleep, you should ascertain that his face be not covered with the bedclothes; if it be, he will be poisoned with his own breath—the breath constantly giving off carbonic acid gas; which gas must, if his face be smothered in the clothes, be breathed—carbonic acid gas being highly poisonous.

You can readily prove the existence of carbonic acid gas in the breathing, by simply breathing into a little lime-water; after breathing for a few seconds into it, a white film will form on the top; the carbonic acid gas
