III (fig 4 ) Diphtheroid baciUi isolated from a case of Hodgkin's disease, by 

 Dr. Rhea — magnification same as in Plate II, and much higher than 

 figs 1, 2, 3 

 IV ,V (fig 1, 2 ) Branched and beaded forms from sputum of case reported by 

 Muster, Pearce and Gwyn — either a streptothrix or a branched and 

 beaded tubercle bacillus (after figs in Trans Assos. Amer. Physicians 

 16: 1901, p. 208). 

 VI (fig 3) Streptothrix filaments, branched and beaded, stained in sections 

 from abcess of human brain — to compare with previous illustrations 

 This was localized without signs of tuberculosis elsewhere, nor did 

 inoculations of the brain material set up tuberculosis in guinea pigs 

 The felted masses as seen in other parts of the section resembled in 

 size and arrangement those present in actinomycosis
