It takes longer for some muscles to dissociate than others, even in the same temperature, so one must try occasionally to see if the action is sufficient. When it is, the acid is poured off and the muscle washed. Fig. 131. Adjustable lens holder for the same purposes as Fig. 130.

If it is de- sired to keep the specimen indefinitely, or several days, the water should be poured off and a half saturated solution of alum added (§ 299). The alum solution is also very advantageous if the specimens are to be stained. The specimens may be mounted in glycerin, glycerin jelly or balsam. Glycerin jelly is the most satisfactory, 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 Gage, Simon Henry, 1851-1944.
