 usualh' found in dying cultures. An indication of the ap- 

 proaching death of a tissue is the emigration of unusually 

 large-sized spherical cells. These cells when closely ob- 

 served under high magnification showed no protoplasmatic 

 connection between them and even with the greatest care, 

 recovery is ver}- difficult to bring about after this stage 

 has been reached. There is no doubt whatever, that the 

 protoplasmic bridges which exist between the tissue celh
