 appear to be identical with the fibres of coagulated lymph.

Malignant growths may be divided into three classes of 

 disease. 1. Scrofula, and its varieties. 2. Carcinoma, or 

 scirrho-cancer. 3. Encephaloid disease, or medullary fungus. 



1. Scrofulous growths present three forms of manifestation. 

 In the lymphatic ganglia and in the conglomerate glands ; in 

 well-defined spherical tubercles, which appear first as small 

 points or grayish granules ; and depositions which appear 

 during the progress of typhus fever, between the muscular and 

 mucous coats of the intestines, in the mesenteric glands, in and 

 under the mucous membrane of the trachea, and sometimes in 

 the substance of the lungs and spleen. Fig. 44 shows the 

 microscopic appearance of typhous matter from the mesenteric 

 glands. A, an amorphous, slightly granular mass, of a 

 brownish-white color, with an immense number of cells depo- 

 sited ; B ; the amorphous mass treated with acetic acid, by which
