76 SCIENCE In normal respiration the air passes freely in and out through the gauze and the tubes E and D. When artificial respiration is necessary all that is needed is to start the apparatus and the air going through the small tube (sm) enters the trachea with sufficient velocity to go well down into the lungs. With this device it is not necessary to closely approximate the volume of the normal tidal air, because any excess escapes at once through O without causing undue pressure in the lungs. An excess of air is therefore always desirable. I have found that four different sizes of This, trachea cannula suffice for our needs. however, requires only a variation in size of These differthe trachea end of the cannula. ent sizes can be made, therefore, so that the anesthetic cone will fit each of them. This device commends itself because of its simplicity, its effectiveness, its cheapness. and the ease of manipulation. STANFORD UNIVERSITY, J. R.

EXTRACTED BY HYDROCHLORIC Long years of experience and continuous factory operation coupled with fortunate climatic and physical conditions have enabled the Munktell Factory at Grycksbo, Sweden, to supply the Chemists of the world with an unequalled product. Aside from the chemical constitution of the paper, which can, of course, be controlled by the laboratory of the factory, other constituent features can only be attained by expert hand manipulations, as, for instance, the weight, texture and uniformity for it must be remembered that all chemists' Filter Paper must from its very character be hand made. Transient help or workmen trained in other lines of paper manufacture, especially those who have worked in factories where paper is made by machinery, cannot be of much use. For generations the sons and daughters of the workmen in this factory have succeeded their parents and the same is true at this date. In this way the necessary "touch" has been developed in these workers from their childhood on. As the chemical industries have developed so also has this factory enlarged its line so that at the present time, as sole United States Agents, we are able to offer from stock for prompt shipment a grade of Munktell's Chemists' Filter Paper to meet any known requirement.
