In the present study, examinations of Feulgen hydrolysis were carried out by the microspectrophotometric measurement of the relative DNA contents in lymphocyte nuclei. Smears of thymus of male mice, 2-month old, were made. The smears were air-dried for at least 1 hour, fixed in methanol-formalin-acetic acid mixed 85 : 10 : 5, in Carnoy's solution or in formalin vapor for 30 minutes, and subjected to the Feulgen-staining procedure. Feulgen hydrolysis was performed either in 1 N HCl at 60℃ in a constant temperature water bath or in 5 N HCl at 25℃ (±3℃). After washing, smears were stained in decolorized basic fuchsin for 3 hours, and rinsed three times with SO_2 for 15 minutes and once tap water for 5 minutes. The relative DNA content was measured in 10 to 20 small lymphocytes from each smear by microspectrophotometry at 560 mμ by the scanning procedure.
