Values of A V for carboxyl and amino groups in the Synopsis and Table I were erroneously given and should read 9.4 and 19.7 cm3/mole, respectively. Consequently, the statement on page 788 that the bV is considerably smaller than that for glycine should be deleted. The value of A V for carboxyl group
## Abstract The titration curve of ultrasonic absorption at 2.82 MHz in aqueous solutions of lysozyme measured by Zana and Lang [__J. Phys. Chem.__, **74**, 2734 (1970)] is theoretically analyzed. The maxima at pH 3 and pH 11 are describable with protonβtransfer reactions of dissociable carboxyl an
The addition of an appropriate mixture of ethanol, water and sodium perchlorate to crude extracts of some biological material results in the selective precipitation of nucleic acids. Detergent extracts of tissue-cultured plant cells treated with this reagent yielded as much as 95-100% of the nucleic
