Improved Procedures for Preparation of Tissues for Chemical Analyses.

Abstract
Improved procedures for the preparation of tissues for chemical analyses are presented in detail. The techniques for drying, extracting neutral fat, and grinding the dry tissues are given. The Zassenhaus spice mill for grinding is illustrated. The detailed procedures have definite advantages over all previous procedures; they are saving in time and effort; they permit a routine for all types of tissues; they produce homogenous materials that insure adequate sampling.
