may be conspicuous without being exclusive, 

 but may also be so assertive as to be absolute. 

 Then, again, when the characters of the 

 parents are reproduced in the offspring they 

 may be equally intermingled, or they may 

 appear in patches. In cattle the former 

 condition of things, so far as hair colour is 

 concerned, is illustrated in blue-grey Short- 

 horn-Angus or Shorthorn-Galloway calves, 

 where the whiteness of the father and the 

 blackness of the mother reappear as black 

 and white hairs which occur equally all over 

 the animal's body. The other condition of 

 things inheritance of colour in patches is 

 illustrated by the piebald, where the black 

 and white colours are separated in distinct 

 areas. This result is called participate in- 

 heritance, and amongst plants is best illus- 

 trated by that curious hybrid laburnum, 

 Cytisus Adami, which is a cross between the 

 ordinary laburnum with yellow flowers, and 

 another laburnum whose flowers are purple. 

 In Cytisus Adami we find flowers in whose 

 petals the colours of both parents are blended ; 

 but we have also, on the same plant, yellow 

 flowers, which are indistinguishable from 

 those of the common laburnum, and purple 

 flowers, of precisely the same colour as those 

 ef the purple parent.
