appearance of two closely connected spherical bodies without any 

 visible partition, and somewhat resembles the shape of a figure 

 8. At this stage the now bispherical micrococcus is about 

 twice as long as its transverse diameter, or measures about 1.5 m. 

 In the interior of each spherical body a somewhat darker sub- 

 stance, or a kind of a nucleus can be observed. This duplication, 

 or process of division, which occurs in a large number of micro- 

 cocci at the same time, it seems, finally breaks the glia, or the 

 viscous mass, which apparently holds the micrococcus cluster 

 together; the micrococci, many, or perhaps most of them now 

 bispherical, and some yet single, become free and make their exit. 

 Whether the glia constitutes the pabulum needed to effect this 

 growth and duplication, and is gradually consumed, cr whether

 found, though seldom in large numbers, in the fresh blood and 

 blood serum ; and are very numerous, and often very large in the 

 morbid tissues, the exudations, particularly the lung exudations, 

 and blo'od extravasations, and in the morbid products in general. 

 I never found them absent. The bispherical, and also the single 

 micrococci, when freed from their glia, do not cease to multiply 

 by fission ; on the contrary, the process of division proceeds with 

 great rapidity, provided the temperature is not too low. At an 

 ordinary temperature, say about 70 to 75 °, a double or bispheri- 

 cal micrococcus is often changed into a small chain of two double 

 micrococci, connected endways, in less than 5 minutes. While 

 the process of division is thus going on, and the single cells of 

 such a bispherical micrococcus are becoming double by a longi- 

 tudinal growth, and becoming contracted in the middle, the orig-
