LABORATORY MANUAL 
Lecture Notes: Lecture notes should be written up in such manner 
that the note book is presentable at any time it may be called for. Each 
day’s lecture should be begun on a new page, and should bear a date. 
The above does not refer to instructions given preceding the laboratory 
period. If the instructor so desires he may call for the manual and labora¬ 
tory notes at any time. 
Reports: The regular reports should be made on 8x11 paper and handed 
in at the period following the performance of the experiment, unless other 
arrangements are made by the instructor. The reports should be written 
with ink or typewritten and should be in the form outlined below: 
1. Number of experiment; name and number of student. 
2. Object: As given in the manual. 
3. Procedure: Apparatus used; a brief description. 
4. Observation: Filled in and copied in exercise as outlined in the 
manual. 
5. Questions: The question should be copied, and it should be followed 
by a comprehensive, but concise answer. Additional questions may be 
given by the instructor. 
A two-inch margin should be left on the left hand side of the page for 
notations by the instructor. Corrections should be made as requested and 
the exercise should again be handed in for credit.

Introduction to second revised edition 
Since the publication of the first edition of this Manual, it has been 
found advisable to make a number of minor changes so that the exercises 
might be of a greater general interest. It has also been deemed advisable 
to drop several little used exercises and replace them with exercises per¬ 
taining to more recently developed dairy tests. It was also thought 
advisable to enlarge the appendix by the addition- of a number of tables 
of general interest to the student of dairying.—L. C. T.
