anything like Mendel's phenomena of dominance and segregation has occurred 
in the history of Telephone, is clearly absurd. 
(5) Duke of Albany resembles Telephone so closely in the general characters 
of its seeds, that I have only examined a small sample, sent to me by 
Messrs Sutton and Sons. The frequency of colour varieties in this sample 
is given in Table IV. 
(6) The Hybrid Descendants of Stratagem. It has already been pointed out 
that the average colour of Stratagem must be regarded as a blend of yellow and 
green. The yellow properties of this blend are well seen in Daisy, the result of 
the cross Stratagem x Giant Marrow. In shape, the seeds of Daisy are generally 
oval, with two opposite concave faces, the whole surface being wrinkled to a 
variable extent. Forms intermediate between this and the thinner flattened form 
of Stratagem also occur, as do more rounded forms. The chief shapes may be 
gathered from Figs. 9 and 10 (Plate II.). The average colour is a fairly uniform 
green ; but as will be seen from Table IV., piebald individuals, and individuals of 
colour 4, occur. 
Daisy and Lightning were crossed, as has been said, to produce the race Early 
Morn. In its present condition Lightning is a very round and smooth-seeded 
Pea, the shapes which occur being shown in Figs. 13 to 15 (Plate II.). The 
wrinkles of the group photographed in Fig. 15 occurred in about 16 out of '250 seeds 
examined. The colour varieties include a small percentage of green and piebald 
seeds ; but the great majority of the seeds are of a deeper orange than that 
of Group G. Lightning is what I imagine most of the writers on Mendel's 
laws would accept as a typical round, smooth, yellow Pea. The seeds of the 
second generation (produced by the first hybrid plants) were variable both in 
shape and colour. Messrs Carter and Co. have circulated reproductions of a 
photograph of one pod, containing peas of the second generation. The pod 
contains seven seeds, of which three are labelled " white," three " blue," and one 
"green." Two of the seeds seem smooth, while the rest are wrinkled in various 
degrees. By the kindness of Messrs Carter and Co. I have been able to examine 
a sample of Early Morn not as it is now, but as it was when they introduced it. 
The race was apparently selected from seeds of the second hybrid generation 
which were " recessive " both in colour and in shape ; and although we must 
remember that the seed saved when making the stock from which a new race 
might be established was selected, and cannot be supposed to represent all the 
seed produced by the offspring of all the green and wrinkled hybrids, yet so far 
as the evidence available goes it favours the view that the offspring of wrinkled 
seeds were themselves wrinkled, for the sample given to me contains only 
wrinkled seeds of fairly uniform character. These seeds do not in the least 
resemble the seeds of Daisy. As will be seen from Figs. 16 — 18 (Plate II.), they are 
far more like those of Telephone in the character of their wrinkles than they are 
like either of their parents. This is another example of the danger incurred by
