 Bacterium acidi lactici. Hiippe. (Lactic Acid Bacillus.) 



I. Gelatin stab culture, five days at 22°. The stab 

 canal in nature is somewhat whiter. 



II. Agar streak culture, five days at 22°. 



III. Agar stab culture, three days at 22°. Stab canal. 



IV. Agar stab culture, three days at 22°. Surface 

 growth. 



V. Agar plate, three days at 22°. Natural size. 

 VI. Agar plate, three days at 22°. X 50. Upper colony 

 superficial, lower colonies deep. Compare also Plate 18, 



VII. 



VII. Gelatin plate, two days at 22°. Natural size. 

 VIII. Gelatin plate, two days at 22°. X 50. Upper colony 

 superficial, lower colonies deep. The superficial colonies 

 may vary very much. Compare also Plate 16, viii, ix; 

 Plate 17, 1, 11; Plate 19, iv, vn. 



IX. Microscopic preparation. Pure culture from an 

 agar colony. X 800.
