AETIOLOGY OF TUBERCULOSIS.

5.—Servant girl of nineteen years ; mother died of phthisis ; had suffered 
for a year from cough ; of a delicate build, short breathed and had profuse 
sweats. Death after seven weeks’ stay in the hospital. In the left upper lobe 
of the lung a moderately large vomica. The remaining part of the lobe infil¬ 
trated and lobular ? (lobuliire) caseous herds, close together, partly with central 
decay. On the right almost the whole lung infiltrated with greyish yellow 
caseous masses and with many softened spots. In the trachea flat ulcerations. 
In the ileum and in the beginning of the colon numerous abscesses with indented 
borders. Mesentric glands partly freshly caseously infiltrated. As well in the 
interior of the vomicse as in the caseously infiltrated parts of both lungs extra¬ 
ordinary numbers of bacilli w^ere found, mostly heaped together in nests. Also 
in the intestinal abscesses and mesentric gland tuberculous bacilli were present 
in considerable numbers. 
3.—Tuberculosis of Various Organs. 
The cases of tuberculosis examined by me to be mentioned under this di¬ 
vision concern single organs which have been obtained, partly from operations, 
partly from sections, without my knowing anything further of the course of 
the disease or of the other results obtained from the sections. I can on this 
account only mention them summarily here. 
Two cases of tuberculous abscess of the tongue. At the base of the ab¬ 
scesses and in places forcing themselves deep into the tissue of the tongue, 
thick swarms of tuberculous bacilli were found. 
Tuberculous bacilli were just as abundantly present in four cases of tuber¬ 
culosis of the pelvis of the kidneys, in one case of tuberculosis of the bladder 
and of the urethra, once in tuberculosis of the surenal gland, and in a case of 
tuberculosis of the uterus and of the tubi. 
On the contrary, the number of tuberculous bacilli was very small in five 
tuberculous testicles removed by operations. They could only be proved here 
singly in the numerously present giant cells. 
Just the same behavior showed itself also in two cases of large solitary tu¬ 
berculous herds of the Ijrain. The appearance of the bacilli here also confined 
itself to the giant cells. 
The only case belonging here in which no tuberculous bacilli at all could 
be proved concerned the examination of pus which came from a tuberculous 
abscess of the kidneys. Inoculation with this pus had given a positive result, 
therefore infectious germs must have been present in the same. We shall 
speak of this case later and give explanation for the negative result of the mic¬ 
roscopic examination. 
4. —Scrofulous Glands. 
The scrofulous glands which I have examined I owe for the most part to 
Privy Councillor Badeleben, who placed the same at my disposal directly after 
they were removed. Twenty-one cases in all were examined in which the 
glands showed themselves tuberculous. I understand by this the presence of 
epithelioid cells which are grouped in herds and enclose more or less num¬ 
erous giant cells. With few exceptions, in which a necrosis and caseous degen¬ 
eration of the diseased gland tissue had not yet appeared, these cells were
