JMoussu has almost always found gastric strongylosis associated with pulmonary or tracheo-bronchic strongylosis, but Lignieres asserts that the Argentine cases showed nodules of hepatisation which had nothing to do with the pulmonary strongylosis, and which appeared to result from areas of pneumonia produced by the specific cocco-bacillus and other organisms. He has even found abscesses and cavernous spaces in the lung. Pathogeny. According to Lignieres the specific agent of pernicious ansmia is a cocco-hacillus which stains well with fuchsin, violet, blue, safraniu, etc., but does not take Gram, and which in cultures assumes either the strepto-bacillary form or occurs in barrel-shaped masses. It grows in simple bouillon at 38" C, but better still in peptonised bouillon, -which turns tur- bid for five or six days, afterwards becoming lim- pid in consei]uence of the organisms falling to the bottom of the vessel. It does not coagulate milk. On agar the culture is thin, bluish, shows an iridescent reflection, and when old appears whitish. Grown on gelatine, the appearances are similar—the gelatine is not liquefied ; on serum the pellicle is scarcely visible. The organism is said to be pathogenic for guinea-pigs, rabbits, dogs, and, of course, for sheej). Moussu, however, does not consider that the reported cases of transmission through the blood stream or hy subcu- taneous injection are really convincing or characteristic. He does not question the fact that Lignieres discovered a special pathogenic agent in all cases and in all his patients; but what aj)pears to him debatable is the exclusive part which Lignieres attributes to that agent. The fact that in Argentina, just
