[摘要] In the article entitled “Studies on Blood Platelet Phospholipids,” by Marcus et al., in the January, 1960, issue, the words Dinitrophenyl Ethanolamine and Dinitrophenyl Serine should be substituted for Dinitrophenylhydrazine Ethanolamine and Dinitrophenylhydrazine Serine on lines 5, 6, and 7 in the left-hand column of page 184. It is to be noted that the abbreviation DNP as used elsewhere in the article refers to dinitrophenyl.
