tubing is used, the one-eighth inch connection is cut off, and for larger sizes both of the two smaller joints are removed.The valve is placed in the side wall of the connector in such a position that no air bubbles will pass into the outlet tube even though the fluid is allowed to flow freely from the one-eighth inch outlet under a head of 6 feet of water. This is a rate of flow greatly in excess of any used in practice.An important advantage of this valve lies in the fact that the attending nurse can tell at a glance, by observing the flow of air bubbles through the fluid, whether or not the apparatus is in operation.

of Physicians and Surgeons NEW YORK A chronic inflammatory disease of the scalp, primarily perifollicular, leading to suppuration and extensive undermining of the involved area, was given the name Perifolliculitis capitis abscedens et suffodiens by E. Hoffmann. He presented such a case before the Berlin Dermatological society, Nov. 12, 1907. Hokmann's patient, a man aged 25, had then been afflicted for a year, and showed "on the occiput many (about 20) nearly hazelnut sized, pale, hemispherical elevations, hairless or covered at the borders with sparse, short hair stumps, from which on pressure pus exuded and into whose fistulous openings the sound could be introduced up to 4 or 5 cm. Beside these closely crowded tumors with smooth, pale, grayish-red surfaces, which gave the scalp a rough, uneven, mammillated appearance, there were a few disseminated pustules and crusts, pierced by hairs, and isolated, small coin-sized, smooth scars. Healing resulted in further scar formation and was hastened by a 10 per cent, sulphur-zinc paste. Microscopically there was no fungus ; cultural investigation for sporotrichosis proved negative. There was, then, a suppurating folliculitis, undermining the scalp, with formation of fistulae and termination in cicatrizing alopecia." The American, and to the best of our knowledge, the British, French and Italian literature contains no record of this entity ; but in the German dermatologie publications we find that A. Ruete 1 has carefully described the disease in an article which deserves to be reviewed in detail. In the introduction he mentions the numerous processes leading to scarring of the scalp or to alopecia associated with scarring, touching on syphilis, tuberculosis, favus, lupus erythematosus and the innominate cicatricial alopecias of Besnier, which include folliculitis decalvans Read before the Section on Dermatology and Syphilology at the Seventy\x=req-\ Second Annual Session of the American Medical Association, Boston, June, 1921. 1.
