234 THE ORCHID REVIEW. [Aucust, 1909. 
The sepals and petals may be described as deep carmine rose, and the lip 
deep flesh pink, with a pair of orange keels at the base. The column 
wings are lilac-purple, and approach those of the Cochlioda parent in shape. 
The colour is very brilliant, and the plant should develop into a fine thing 
when it becomes strong, for the Miltonia parent produces a spike of several 
flowers, and the Cochlioda parent quite a long raceme. Only one hybrid 
between Cochlioda and Miltonia is known to have flowered, namely 
Miltonioda Lindeni, which was described at page 58 of the present volume, 
and whose parentage is not quite certain, though it is believed to have been 
derived from Cochlioda vulcanica and Miltonia Phalznopsis. Other 
. seedlings between the two genera are in existence, and the next few years 
may witness some striking developments. Quite recently the existence of 
hybrid seedlings between Cochlioda and Ada and between Cochlioda and 
Oncidium have been recorded, and the linking up of other allied genera 
is probably only a question of time. The progress made in hybridisation 
during recent years is indeed remarkable, and the field for experiment in the 
future seems inexhaustible, for the hybrids themselves are so frequently 
fertile when again intercrossed.

NATURAL SELECTION AND THE ORIGIN OF SPECIES. 
In the course of an interesting address given at the recent Darwin 
Celebrations at Cambridge, Prof. Ray Lankester remarked that after fifty 
years of examination and testing, Darwin’s theory of the origin of species 
by means of natural selection, or the preservation of favoured races in the 
struggle for life, remained whole and sound and convincing, in spite of every 
attempt to upset it. In the judgment of those best acquainted with living 
things in their actual living surroundings, natural selection retained the 
position which Darwin claimed for it of being the principal means of the 
modification of organic forms. The nature of organic variation, and the 
character of the variations upon which natural selection can and does act, 
were not neglected or misapprehended by Darwin, and the notion that these 
variations are large or sudden was considered by him, and for reasons set 
forth at considerable length rejected. In regard to the important facts of 
heredity connected with the cross-breeding of cultivated varieties, especially 
the blending or non-blending of their characters in their offspring, and the 
question of prepotency, it was important to recall the full and careful con. 
sideration given to this subject by Darwin. We could not doubt that he 
would have been deeply interested in the numerical and statistical results 
associated with the name of Mendel. These results tended to throw light on 
the mechanisms concerned in hereditary transmission, but it could not be 
shown that they were opposed in any way to Darwin’s great theoretical 
structure, his doctrine of the origin of species. It had often been urged
