PREFERENCE FOR PARTICULAR COLOURS. 305 
oue in Middlesex—and spreading the observations over 
some time, so as to experiment with different bees, 
and under varied circumstances. Adding the numbers 
together, it of course follows that the greater the 
preference shown for each colour the lower will be the 
number standing against it. 
The following table gives the first day’s observa- 
tions in extenso :—

In the next series of experiments the bees had 
been trained for three weeks to come to a particular 
spot on a large lawn, by placing from time to time 
honey on a piece of plain glass. This naturally gave 
the plain glass an advantage; nevertheless, as will be 
seen, the blue still retained its pre-eminence. It seems 
hardly necessary to give the observations in detail. 
The following table shows the general result :—
