INFLUENCE OF LIGHT ON PLANTS. 



At the recent meeting of the British Association, Mr. Hunt, who is 

 so well known for his researches on light, read a report " On the 

 influence of Light on the groAvth of Plants." The author confirms the 

 conclusion, tliat seeds will not germinate under the influence of light 

 separated from the chemical principle with which it is associated in 

 the sunbeam ; that germination being eflfected and the first leaves 

 formed, light — the luminous raj's — become essential to the plant to 

 enable it to secrete the carbon obtained from the carbonic acid of the 

 atmosphere ; and that the increased action of the heat rays are essential 

 to insure the production of the reproductive elements of vegetable life. 

 It is found that the chemical principle of the solar rays is more active, 

 relative to lieat and light, during the spring than at any other period 

 of the year : that as summer advances this power diminislies, and 

 luminous force increases, whilst with the autumn both light and 

 actinism are subdued, but the calorific radiation increased. Thus we
