THE COMMUNICABLE DISEASES 497 
probably primary as it is not known that the retropharyngeal glands 
drain to or from the larynx. About the lesions on the laryngeal mucosa 
there is an area of congestion probably due to the tuberculin injection. 
Local lymphatic tuberculosis of comparative interest 
was encountered a few times. Three cases of cervical 
adenitis, large enough to be visible, were seen, of which 
one broke dov/n about two weeks before death, and dis- 
charged. The others did not ulcerate through the skin 
but, contrary to the usual rule for the human being, 
remained as isolated glands only lightly adherent to one 
another where they lay adjacent. There was also seen 
an ulcerating tuberculous lymph node in the groin of one 
monkey, the animal having rather pronounced abdominal 
and pelvic tuberculosis. Two instances of tonsillar tuber- 
culosis are recorded, in both of which the lesion was of 
some duration and associated with caseation in the lymph 
node lying immediately behind and below it. A Guinea 
Baboon {Papio sphinx) had as. an unusual part of his gen- 
eral tuberculosis, an active caseopurulent collection in the 
antrum of Highmore, which attacked the upper maxilla 
and immediately adjacent muscle ; tubercle bacilli could be 
demonstrated. 
One of the cases of nodular or massive peritoneal 
tuberculosis is quite like the tumor-forming variety of 
human adolescents ; it is as follows : 
Reddish Macaque (Macacus nifescens). Caseous tuberculosis of 
mesentery and spleen; miliary tuberculosis of lungs, pleura and liver; 
chronic myocarditis. The lymphatic glands of the posterior and supe- 
rior mediastinum and bronchi are slightly enlarged, soft and anthracotic 
but do not show any tuberculous change. Both lungs are riddled with 
small, firm, gray miliary tubercles, some surrounded by a clear mantle 
of connective tissue. The intervening lung is practically normal. Pleura 
over base of right lung on both surfaces shows small, pale miliary 
tubercles. The liver contains various sized miliary tubercles. There 
is a large caseous mass in posterior end of spleen with adhesions to 
kidney, stomach and colon. Retroperitoneal glands are much enlarged, 
firm, homogeneous — probably tuberculosis of a different type. Lesser 
omentum contains one caseous gland. Few caseous glands in great 
omentum. In the right iliac region there is a large mass involving many 
coils of intestine. It is found to arise probably from the ileocecal
