lls being 2 to 4times the breadth of a colourless blood-corpuscle. These cells occur chiefly in themorning sputum in individuals over 30 years of age. In younger persons theirpresence indicates a pathological condition of the pulmonary parenchyma(Guttman, H. Schmidt, and Bizzozero). They often undergo fatty degeneration,and theyjnay contain pigment granules (3); or, they may present the appearanceof what Buhl has called mydin degenerated cells; i.e., cells filled with clearrefractive drops of various sizes, some colourless, others coloured particles, thelatter having been absorbed (4). Mucin in the form of myelin drops (5)) isalways present in sputum. 2. Lymplwid cells (9) are to be regarded as colourless blood-corpuscleswhich have wandered out of the blood-vessels; they are most numerousin yellow sputum, and less numerous in the clear, mucus-like excretion.The lymph-cells often present alterations in their characters; they maybe shrivelled up, fatty, or present a granular appearance.

ACTION OF THE ATMOSPHERIC PRESSURE. 275 The fluid substance of the sputum contains much mucus arising fromthe mucous glands and goblet cells; together with nuclein, and lecithin,and the constituents of saliva according to the amount of the lattermixed with the secretion. Albumin occurs only during inflammation ofthe respiratory passages, and its amount increases with the degree ofinflammation. Urea has been found in cases of n
