The analytic results in the above table are those for seeds of the plants, 

 except in the last five cases. They are compiled from a number of sources. 

 Among the plants studied for their phyto-phosphate content, in which the rela- 

 tive amount of this substance is not given, are the following: Beta vulgaris, 

 Brassica campestris, Cucurbita pepo, Ervum lens, Lupinus albus, L. angustifolius, 

 L. luteus, Pinus laricio, P. maritima, Sinapis nigra, Solanum tuberosum, and the 

 tubers of AI Hunt cepa and Dahlia variabilis. In only two materials reported, 

 namely, rutabaga root and alfalfa hay, could no phyto-phosphate be found. In 

 several instances the total phosphorus was not reported. Where there is a 

 close agreement between two or more results, only one figure is given above.
