    are pushing their way into a portion of a breast which to the naked eye appeared unaffected. It may be that these lymph corpuscles are generated where they are found, and are not there by infiltration or intrusion. The Drs. Hoggan say these cells are derived from the blood-vessels, attracted as it were through the walls by the stimulus to such movement as is given by the cancerous process going on in their immediate neigh- bourhood. What the share is of the epithelioid and the lymphoid cells respectively in the contamination is a problem that will possibly be solved by further experiments in a bac- teriological direction. The Drs. Hoggan* describe the infection of cancer through the lymphatic system. They differ from Koester mainly in denying the participation of the endothelial cells of the lymphatics themselves. They say that the cells of the lymphatic wall ultimately become infected by the cancer cells, but are not the primary agents of cancer dissemination ; but that cancerous cells of the lymphatic wall infect the wandering cells on the other side of the wall, and thus become the focus of the secondary tumour. They add that cancerous lymphoid or wandering cells infect the cells of the fixed tissues; that nuclei of the fixed cells alone undergo the cancerous change; and that the nucleus of the cell becomes the new cancer cell.
