with tubercle bacilli in the blood ; (2) if there is placental 

 tuberculosis which has produced such lesions that the 

 passag-e of the bacilli is no more prevented ; (3) if there is 

 uterine tuberculosis which favors the occurence of placen- 

 tal tuberculosis; (4) if the amniotic fluid contains bacilli 

 and be swallowed by the fetus. — Medcine. 



Landry's Paralysis. — Dr. Pierre Marie (La France 

 Med.) communicated the observation of a young- g-room 

 who died with typical symptoms of Landry's acute ascend- 

 ing- paralysis. The autopsy revealed a hemorrag-ic soften- 

 ing- of the g-ray substance in the anterior horns. There- 

 fore, the lesion was central, and not peripheral, as main- 

 tained by certain authors. Microbes were found, and in 

 the cervical and dorsal reg-ion they were present in almost 

 pure cultures. Artificial cultures were not made, but, 

 morpholog-ically, the microbe resembled the bacillus an- 

 thracis. 



Diagnosing Typhoid Bacilli. — Lazarus has a made a 

 clinical test of Eisner's method of diag-nosing- typhoid 

 bacilli. He adds one per cent, of potassium iodide to 

 Holz's acidulated potato-g-elatin. Upon this medium the 

 bacterium r^/;develops rapidly, forming at the end of forty- 

 eight hours coarsely g-ranular brown colonies. The typhoid 

 bacillus, on the other hand, g-rows more slowly; the colo- 

 nies at the end of forty-eig-ht hours appearing- like small, 

 g-listening- drops of water with very minute g-ranulations. 



The stools of five patients with typhoid g-ave positive 

 results during- the first, second and third weeks of the 

 disease. After the subsidence of fever, bacilli were occa- 

 sionally found, in one case as late as forty-one days after 

 defervescence. Repeated examinations are necessary, as 

 negative results were shown at times to be false by posi- 

 tive finding-s at a second examination. In one case of 

 typhoid, where remittent fever persisted, the bacilli were 

 found in the stools even up to the ninth week, Neg-ative 

 results were always obtained in patients suffering- from 

 non-typhoidal disease of the intestines. — Medicine.
