NUTRITION AND GENESIS. 485 



for the reason that the cold which arrests reproductive 

 activity also arrests individual activity: growth of the indi- 

 vidual and multiplication of the race vary simultaneously 

 with variations in the seasons. Still there are some familiar 

 facts showing that the external conditions which favour 

 nutrition also bring about reproduction. Early in the year 

 we are supplied with flowers from regions warmer than our 

 own, and by and by there come to our markets fruits and 

 vegetables from the south of France, the Channel Islands, 

 and even from the Scilly Isles, which are much in advance 

 of those furnished by the gardens of our own colder regions : 

 reproduction commences earlier where the light and heat 

 furthering nutrition are greater. And then there is a 

 kindred meaning in the not unfrequent occurrence of a sec- 

 ond flowering and even of a second fruiting in warm, bright 

 and prolonged autumns. Here the abnormal recommence- 

 ment of reproduction is determined by an abnormal increase 

 of nutrition.]
