348 REPORT—1904. 
round pollen x ditto ditto long pollen gives (usually) purple F,.  F., some- 
times has only three colour-types—purple, red bicolor, white ; but others 
have five—purple, purple-picotee, red bicolor, red-tinged white, white. 
On the purple side the great majority have Jong pollen, while of the reds 
most have rownd. Statistical relations not yet determined. The whites 
are 3 long : 1 round. 
Some coloured F, plants give in F; no whites ; and, though the point 
is not yet proved, the presumption is that some failure of segregation 
occurs in gametes of F,. The other possibility is that this phenomenon 
is due to simultaneous homozygosis of independent allelomorphs. 
A family from Lady Penzance x E. Henderson (long), showed abortion 
of anthers in certain F, individuals. The ¢ cells may be fertile. This 
sterility on ¢g side has Mendelian inheritance; but, probably as a 
fortuitous accident, the ratio approaches 4 fertile : 1 sterile (instead of 
3:1). With rare exceptions, coloured types with dark axils are fertile, 
light axils going with sterility. Hence the fertile whites (though light 
axilled) must bear the character ‘ dark axil,’ a point which can be proved 
next year. 
The following scheme shows the probable distribution of forms :

During the year the new Education Act has come into force, and 
many of the new educational authorities, in arranging their work for the 
coming session, are devoting considerable attention to the question of the 
training of teachers. The Regulations issued in July by the Board of 
Education for the training of teachers set out under their professional 
training, as the sum of the whole matter, the following weighty recom- 
mendations, 
‘The students ought to have an adequate knowledge of school hygiene. 
They should understand the general conditions necessary for making a 
building or a room healthy and for keeping it so, and they should be well 
acquainted with the rules of personal health, and, so far as possible, with 
the psychological principles upon which these rules are based. In the
