EXTRACTS FROM EXCHANGES.

those found in recent miliary tubercles, likewise cause tubercu¬ 
losis ; both cause tuberculosis, according to Klebs. 
( e ) Molassez and Vignal have, while investigating certain 
pathological changes caused by tuberculosis, found no bacilli in 
the pathological areas, but on the contrary, u zoogloe of micro¬ 
cocci difficult to stain, which inoculated in guinea pigs caused 
general tuberculosis. 
(/) New cases of tuberculosis induced by inoculation with 
“ zoogloe of micrococci ” have been published by Chantemesse, 
Grancher, and Fedroux have likewise discovered in lesions con¬ 
taining “ zoogloe ” ovoid u cocci ” and short rods. 
Cornil and Babes say, if the tubercle bacilli of Koch are in¬ 
variably present in tuberculosis of the lungs, in most cases of 
tuberculosis of the liver, spleen, kidneys, etc., ought they not, 
if they are the cause of tubercular lesions in general, also 
present in localized tuberculosis, viz., white swelling of joints, 
caries of bone, cold abscesses, strumous glands, and lupus. C. 
and B. have only once, in many sections made from specimens 
of. twelve different cases of lupus, found Koch’s bacillus ; not 
being satisfied with this demonstration they have made a series 
of inoculations with lupus specimens, and were unable to find 
any bacilli in their inoculation cultures. Furthermore, say C. 
and B., in chronic or fibroid phthisis of very slow progress, 
Koch’s bacilli may not be demonstrable in the diseased areas ; 
but the failure to find them with the microscope may give way 
to success as a result of a series of inoculations of culture 
mediums, in which they may finally show themselves. In this 
case we must conclude that the bacilli must have been present 
even though microscopically invisible, or else that they were 
present in the form of spores in the affected areas, which spores 
changed their character and became bacilli only after a series of 
inoculations of culture mediums. 
Nocard and Roux found bacilli in the sputa shorter than 
Koch’s, often accompanied by ovoid swellings called spores by 
Koch. 
One is therefore compelled to admit that other micro-organ¬ 
isms than Koch’s bacilli can cause tubercular lesions, and that 
a variety of lesions may be present in tuberculosis which con¬ 
tain few or no bacilli at all; all of which facts make us doubt 
the entity of the morphological character of the micro-organism 
of tuberculosis inasmuch as the organism has been found by C. 
and B. ; (i) in the state of “ zoogloe ” ; (2) in the state of “ cocco- 
bacteria ” ; (3) in the state of u coccotrix ” (granular rods); (4)
