were made by Dr. A. M. Hageman, Chemical and Metallurgical 

 Dept. Westinghouse Lamp Company. 



In the case of both seedlings and flowering plants, the chlorophyl 

 contents was the same in both groups of plants used in the ex- 

 periment. 



Only in the case of the Tomato plant was a complete determina- 

 tion made which showed 19.8 per cent, starch in the plants grown 

 under normal conditions and 12.6 per cent, starch in the plants 

 grown under forced conditions. Further analysis will be made be- 

 fore conclusions are drawn in regard to the chemical analysis of 

 the plants under the artificial light.
