 interpreted them correctly on one flagellate and wrongly on another, 

 or even reached different conclusions concerning the filaments on diff^er-

 gote flagellates as hypermastigotes. Historical data on the interpretation 

 of adherent spirochetes has been reviewed by Kirby (1924, 1926a); 

 Duboscq and Grasse (1927); and Grasse (1938). Cleveland (1928) 

 discussed their occurrence on flagellates. 



The spirochetes range in length from only 2 p, the minimum for
