matter and "upon using various stains tubercle bacilli 

 were found mingled with the debris of the broken down 

 tissue." Further on, they say that "as tubercle bacilli 

 are always associated with this disease, possibly secondary 

 to the parasite, the danger to the system of these tumours 

 is obvious." 



Although it is apparent from their general remarks about 

 the parasite, that Barnard and Park are dealing with the 

 same worm as ourselves, the above quotations are much at 

 variance with our experience. It would appear, from their 

 description, that abscess formation, caseation and calcifica- 

 tion were almost the rule in the tumours they found, and 

 that these changes were due to the presence of the tubercle 

 bacillus which was always associated with the disease. 

 We have not so far seen this combination of tuberculosis 

 with the worm-nests, and, if it does occur, believe that it 

 must be through a remarkable concatenation of events, for 

 there seems no special reason why the tubercle bacillus 

 should select the worm-nests in the subcutaneous tissues 

 in which to develop. Barnard and Park's references to 

 abscesses the size of cocoanuts and to degenerated nodules 

 in the throat, neck and intestines make us inclined to 

 believe that they were dealing with the presence of two 

 separate and independent diseases, that the really tubercu- 

 lar areas were those found in the above mentioned sites 

 (in which true worm-nests are rare), that the brisket 



degenerated though possibly, in one or two instances, 

 actually invaded by the tubercle bacillus. In fact, we 

 have come to the conclusion that in the examination of 

 their specimens, these authors must have mixed the tumours 

 and abscesses from various parts of the animal, associating 

 truly tubercular abscesses with caseous worm-nests and,
