 the putrefactive bacteria, slender bacilli in chains, two of the 

 stout rods somewhat narrowed at one end, a spirillum, and a 

 curved chain of possibly lactic acid elements, which is seen 

 somewhat out of focus at the edge of the circle in Photograph 

 No. T (Fig. 56). 



Upon continuing the examination a day later, a considerable 

 change was noticed ; the putrefactive bacteria were not so 

 numerous. The rods of all lengths were plentiful, of equal 

 width, and noticed to have bluntly rounded ends. The whip-

shaped rods were not quite as abundant as the others, but 

 many of them were seen with the thick ends discharging their 

 spores, and with spore formation occurring in nearly the whole 

 of the remaining length of the rod. These points are shown in 

 the photographs, Figs. 57 — 58, though many of the rods of both 

 kinds extended far beyond the field of the microscope when 

 using the i/5th objective and No. i ocular. 



The spirilla, which had been somewhat sparse, appeared at
