These thinner and transparent places disappear after a time, and aA-the end of two or three days liquefac- tion of the gelatin commences; complete liquefaction does not occur until the fifth or sixth day, or even later. Along the line of puncture finely gran- ular colonies are first formed, from which long threads are given off, which, form after a short time a tolerably broad zone of threads and spiral zoogloea Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Sternberg, George Miller, 1838-1915.
