CROSS-REACTIONS OF PNEUMOCOCCAL TYPES. QUANTITATIVE STUDIES WITH THE CAPSULAR POLYSACCHARIDES.

Data are given on the amounts of antibody nitrogen precipitated in the crossreactions, often reciprocal, of the specific capsular polysaccharides of the pneumococcal type pairs II and XX, II and XIX, VII and XIV, VII and XVIII, VII and XIX, VIII and XVIII, VIII and XIX, X and XIV, and X and XX. Since little is known of the fine structures of the polysaccharides of Types VII, X, XIX, and XX, rigorous correlations between chemical structure and specificity can not be made, but several tentative conclusions are drawn.

Ammonia excretion by mammalian lung.

The intravenous administration of ammonium acetate to dogs results in measurable levels of free ammonia in expired air. Simultaneous measurement of the physiologic dead space permits the calculation of the partial pressure of ammonia in alveolar air. This finding has implications for ammonium metabolism and transport.
