TUBERCULOSIS. 251 



pharynegeal were only noticed to be affected in one case. On the 

 other hand, the mesenteric glands were particularly affected, some 

 cases presenting large tumor-like masses containing brokefn-do^yn 

 centres. 



Tuberculosisof the Intestines. Tuberculosis of the intestines 

 is rare, and is restricted to slight ulcerations or abscesses. The 

 liver is generally involved to a marked degree, its substance being 

 filled with small knots, also large granular masses milky white in 

 color. In the centre of these is found a broken-down opaque fluid, 

 the result of fatty degeneration. The spleen was noticed to be 

 tubercular in only two cases, and to a slight degree. The kidneys 

 are frequently the seat of tubercular deposits : in twelve cases scat- 

 tered granulations and cheesy abscesses and centres were found in 

 the spinal and membranous substance. These were accompanied by 

 chronic indurative nephritis. Ulceration of the pelvis of the kid- 

 ney was observed in one case. One dog showed but a slightly tuber- 

 cular ureter and bladder. The sexual organs are, as a nlle, found 

 healthy and very rarely attacked by the disease. In rare instances 

 a tubercular testicle is noticed. . 



Tuberculosis of the prostate has been observed in two cases by 

 Cramer. The same author observed a tubercular ovary in one case. 



Clinical Symptoms and Coubse. On account of the various 

 ways in which tuberculosis appears, no positive line of symptoms 

 can be made. Tuberculosis of the lungs only will show marked 

 symptoms, especially if it has made considerable progress, and is 

 very similar to chronic catarrh of the lungs or chronic lobular 

 pneumonia (see this disease). Eapid emaciation, notwithstanding 

 a good appetite, and a quick loss of strength, indicate tuberculosis 

 of the lungs. We can only he positive of our diagnosis by recog- 

 nizing tubercle bacilli within the secretions. 



The simplest method of obtaining tubercle baccilli is to spread 

 the material thought to contain tubercle baccilli over glass slides 

 or a cover slip : the spread is then fixed but must first be dried 

 by passing the slide through a gas-flame, care being taken not to 

 burn it. The spread is then covered with carbol fuehsin and per- 

 mitted to stain for thirty or more minutes. To hasten the staining 

 pass through a gas-flame until steam is seen to arise from the stain. 

 Three to five minutes of this steaming is sufficient, great care being 

 taken not to boil the stain. Then wash in distilled water. The
