Series O. — ExperimenU tcith wet vs. dry diffusion residue. — Conducted 

 by Herr Wrede in Schmerke. — Six cows averaging 1,118 pounds live 

 weight. Three feeding periods of 10 days each, with first transition 

 period 10, second 5 days. Basal rations per head per day in pounds, 

 potato residue 66, hay o,o, chaff 4.4, straw 6.6, palm nut oil meal 2.2, 

 cotton- seed meal 2.8 to 3.o, wheat bran 2.8 to 6.5, and wet or dry beet 

 diffusion residue added to this in quantities as stated. Duration ol 

 experiment from March (> to April 17 — 42 days.
