formation of oval cells which remained attached, in groups of 

 three and four, as short chains, the individuals of which varied 

 in size; and sometimes the terminal pair were at right angles to 

 the others, thus producing a T- or Y-shape. 



Bacillus ii. rarely exhibited the alatiis-iovm. The typical cell 

 was oval and stained terminally. Mixed with these were bent 

 rods staining irregularly and evidently containing two, three, or 

 four oval cells within a rod-shaped capsule. The exclamation- 

 mark (!) form was genei'ally seen, and in some films Y-forms were 

 noted. It was clearly of the Ehizohiutn-ty^e, while Bac. i. was 

 evidentl}^ allied. 



The respective slimes were obtained in quantity by growing 

 Bac. i. on saccharose-bean-agar, and Bac. ii. on levulose-asparagin- 

 agar. From these slimes, gums were prepared according to the 

 method used in the preparation of other gums.* The slime 

 squeezed from the sponge was precipitated with alcohol, treated 

 with water, and made to yield its gum in the same fashion. All 

 the gums were tested with various reagents with the following 

 results.
