growth and rapid multiplication of the bacilli; or when 

 associated with elastic fibers or areoli, indicating des- 

 truction or breaking down of lung tissue, then a positive 

 diagnosis of pulmonary phthisis and unfavorable prog- 

 nosis should be made. 



The presence of the bacillus pneumonia? of Fried- 

 laender in the sputa, if in quantity, is positive evidence 

 of pneumonia and when associated with dead pus in 

 quantity is evidence of pneumonic abcess and with 

 copious expectoration indicates the abcess is being dis- 

 charged through the bronchi with probable recovery. 

 But if the bacilli of tuberculosis are also present, it 

 changes the diagnosis to pulmonary phthisis with mul- 

 tiple abcess of the lung, a hopeless case with rapid fatal 

 termination. 



The presence of pus, if in quantity, in the sputa and 

 especially if dead pus, is evidence of an abcess some- 

 where in the respiratory tract or in the lungs and when 

 broken down tissue is also present the character of the 

 debris will locate the abcess and so we may by micros- 

 copical examination of the sputa, noting the presence or 

 absence of certain well-known micro-organisms and the 

 presence or absence of the various pathological pro- 

 ducts, not only make a positive diagnosis and prognosis 

 but often in unfavorable cases tell how long the patient 

 will live with no other data upon which to base an 

 opinion. 



EXAMINATION OF URINE. 



For the detection of bacillus tuberculosis in the urine, 

 dry cover glass preparations must be made and stained 

 in the usual way. Also for the detection of the gono- 

 cocci in the urine. Dead pus can only be recognized after 

 staining in dry cover glass j^reparations. 



Tnhe casts. — Since the days of John Bright, of Eng- 

 land, the presence of tube casts in the urine have been
