To clear the medium add one or two eggs, well beaten in 25 of water, boil for forty-five min- utes, and filter through a thin filter of absorbent cotton. Add the glucose after clearing. The reaction of the medium is most important; it should never contain less than 2 per cent, of normal acid. The tube medium contains agar, 5 grammes; gelatin, 80 grammes; sodium chloride, 5 grammes; meat ex- FlG.
