Joty—The Bright Colours of Alpine Flowers. 153 
day when it is done with vitality, for the explanation of that 
preparation for momentous organic events which is in progress: 
throughout the entire course of development, and to the economy 
involved in the physiological welding of processes for the pheno- 
menon of physiological memory, wherein we see reflected, as it 
were, in the development of the organism, the association of 
inorganic restraints occurring in nature which at some previous 
period impressed itself upon the plastic organism. We may pic- 
ture, somewhat crudely, the seedling at Upsala swayed by organic 
memory and the inherited tendency to an economical prepara- 
tion for future events gradually developing towards the esthetic 
climax of its career. In some such manner only does it appear 
possible to account for the prophetic development of organisms, not 
alone to be observed in the alpine flowers, but throughout nature. 
And thus, finally, to the effects of natural selection and to 
actions defined by general principles involved in biology, I would 
venture to refer for explanation of the manner in which flowers om 
the Alps develop towards their unusual beauty.
