Nos. 5309 and 5343. Common Opossums 6" 9 
(Didelphys virginiana). Osteosarcoma of jaw bones. 
This was malignant only in the sence that it interfered, 
by its size, with chewing and thus affected the animaFs 
nutrition. 
No. 5461. Common Hedgehog (Erinaceus 
europacus). 
Sarcoma of lymph-glands, spleen, liver, and lung. 
This tumor is still to be studied for more detailed report. 
It bears some resemblance to hypernephroma but if 
it be, it must be a misplacement tumor as the adrenals 
seem unaffected.
