neighborhood or in contact with them (fig. 6). I have been 

 unable to find leucocytes ingesting entire or large fragments of 

 erythrocytes as was observed by Lewis ('04) who worked with the 

 ungulates and by Weidenreich ('08) who worked with guinea- 

 pigs. A possible reason for amphibian leucocytes not ingesting 

 entire erythrocytes is found in the large size of the red blood cells 

 in this class of animals.

The first evidences of muscle degeneration are marked by a 

 collection of leucocytes among the muscle fibers. The number of 

 leucocytes that accumulate between the fibers is so great that 

 the width of the intercellular spaces is increased to several times 

 their normal extent (fig. 5) . In this accumulation of white blood 

 cells the great majority are the smallest of the leucocytes. Their 

 nuclei are large, taking up almost the entire cell body. The out- 

 line of the nuclei which vary, may be round, shghtly elongated, 

 gently dented on one side or irregularly crescent-shaped, indicat-
