EXPLANATION OF TABLES. 
The methods of comparison of results must, of necessity, be 
more or less largely tabular. Under each head, so far as practi- 
cable, we shall present three tables, A, B and C. 
Table A will contain data pertaining to each individual cow 
for each period of lactation completed and will, therefore, con- 
. stitute the basis of a comparison of individuals and of breeds. 
Table B will contain the same data averaged for all the cows 
of each separate breed for the different periods of lactation; in 
other words, the data will represent a comparison of breeds and 
not of individuals. 
Table C will contain the average results by breeds for all 
periods of lactation, arranged in order, commencing with the 
lowest; and, also, a modified arrangement, showing the compara- 
tive results based on 100 as representing the lowest. This will 
show a comparison of both actual and relative values. Each 
- table will also show the number of cows of each breed repre- 
sented by the results, and, in addition, the aggregate number of 
lactation periods completed by those cows. : 
PRECAUTIONS TO BE ORpsERVED IN Stupyine Resvtts. 
The method of comparison used would be open to criticism, if 
the data were put forward as representing final results. We 
desire to emphasize the statement that these results are liable to ~ 
greater or less modification. Final judgment can be rendered
