 289-293), and the differential characters existing between 

 blennorrhcea of the conjunctiva and catarrhal ophthalmia, 

 succeeded in cultivating the bacilli of the catarrhal or true 

 Egyptian conjunctivitis. He showed that they do not grow 

 on peptone or gelatine ; on blood-serum or on Agar they 

 grow well between 28-36" C, forming in thirty to forty 

 hours small white punctiform colonies, prominent over the 

 surface of the medium ; when closely sown {e.g., in streak 

 culture) they soon coalesce into a whitish-grey band of a 

 fatty, glistening appearance ; the margin of the band is wavy 

 or crenated. Animals inoculated on the conjunctiva with 

 the conjunctival secretion or with the culture prove refrac- 

 tory ; but Kartulis succeeded in producing with the culture 

 the typical catarrhal conjunctivitis in one out of six cases. 

 The pus corpuscles resulting in this case were crowded with 

 the characteristic bacilli. This one case was that of an in- 

 dividual twenty-five years old. 



I append here the illustration of a bacillus of septiccemia of 

 man. In several cases of human septicaemia I have found 

 in the blood-vessels of the swollen lymphatic glands large 

 numbers of minute baciUi, slightly thicker than those just 

 mentioned. They form continuous masses, both in the 

 capillaries and in the minute veins, amounting in some 

 cases to veritable emboli. They occur isolated or in short 

 chains, their length about i /a to 2 '5 /*, their thickness about 

 o'3 /x, to o'5 /* ; no cultivations having been made, the 

 characters of these bacilli could not be ascertained.
