of the ordinary crimson clover and sowed part of it on a 
bed of about five square meters. Two of the seedlings 
were tricotylous and one was tetracotylous, and these 
were transplanted to a special bed as soon as possible 
in the hope that tkey would exhibit the desired abnor- 
mality. This hope was based on the principle of the 
correlation between different kinds of anomalies. 1 If a 
plant exhibits an anomaly in its early stages it will, ac- 
cording to this principle, be more likely than any other 
individual in the same culture to give rise to other devia- 
tions later on. In this particular case my expectation 
was fulfilled, for the tetracotylous plant produced one 
4-foliate and one 5-foliate leaf in the course of the sum- 
mer. Such were not found on any other plant, either 
during the course of the experiment or at the end of 
July when the plants were in full bloom and were pulled 
up and minutely examined. There were about a thousand 
plants. 
I left the three selected specimens to flower together 
and sowed their seeds in April 1896. Over 600 seedlings 
came up, all of them with only two cotyledons. In all 
of them the first leaf was single, which is the general 
rule in clovers (Fig. 47 A). The second and third leaves 
developed in May; they were quite normally trifoliate, 
with the exception of one, of which one of the three 
leaflets was" split laterally, although not completely di- 
vided. The form of this blade was similar to that figured 
in Fig. 45 B. About 250 individuals of the whole group 
were planted out. The seed had been sown in pans; the 
young plants were transplanted into pots and were planted 
in the beds ir the middle of May. At the end of June,
