ADDITIONAL INFORMATION ON R E F E R E N C E S * RELATED TO C H A P T E R 8
In addition to the procedures described in detail in the preceding pages of this chapter, the author wishes to call to the attention of the reader many of the investiga
tions in connection with the microdetermination of nitrogen by the Kjeldahl method. These are listed in Table 19 and the same plan is used here as was used in the preceding chapters. (See statement at top of Table 4 of Chapter 1, regarding completeness of this material.)
