 in a specially con«triicted thermostat. In most cases the gra- 

 nule cliinip was situated at one end of the spirochaete, but in 

 some (fig. I, n'^ 18-21, and fig. II, n"^ 5-7 ; it was placed either 

 centrally or sub-terminally. 



In thèse fourticks, besides the forms connected wilh the gra- 

 nules, there were also présent other spirochaetesof ail sizes,

from those seen in the blood of a mouse or a monkey. They 

 were ail highlyrefractile and quite homogeneous in appearance. 

 The granule clumps associated with the spirochaetes showed 

 no obvions différence from those commonly found, with the 

 exception that they were somewhat smaller and the number of 

 granules fewer; they gave the impression that a portion of the 

 granular substance was used up in the formation of the new 

 spirochaete.
