Chromatm resists the action of dit/i.-sliue fluids much 

 longer than the albumins do ; so that a moderate digestion 

 serves to free the chromosomes from any caryoplasmic gran illa-

 up the cytoplasm. UNNA (Monatschr. prakt. Derm., xxxiii, 

 1901, p. 342) digests tissues in solutions of sodium chloride, 

 to remove the granoplasm.
