Occasionally the hard ringresulting from the contraction of the cancer acts as a polypuswill, and produces intussusception. I have operated on sucha case. The chief difficulty with which surgeons have to contendin the diagnosis of cancer of the gastro-intestinal tract is theabsence of specific symptoms. When a lump in the stomachor intestine is exposed in the course of an operation, eyes andfingers are often incompetent to decide for or against malig-nancy.

The CEecum is occupied with a cancerous mass,which has perforated its mesial wall, and not only implicated the adjacent seg-ment of the ileum but has penetrated its lumen.

On microscopicexamination, however, the presence of giant-cell systemsaffords an unerring means of distinction. Inflammatorythickenings around the ctecum often cause great difficultyin diagnosis. A large proportion of patients with intestinal cancersuccumb from the effects of obstruction; in some death isbrought about by other means. For example, the retentionof the contents of the bowel leads to dilatation of the gutabove the stricture ; th
