takes place as well. The coloured germs swell at 30 C. so vigorously, that many 

 scon burst out of the seed coat. When the partly blue germs, freed from the seed 

 coat, germinate on filterpaper, they yield part of their pigment to it, but especially in 

 the meristem of the germroot it continues to show for several days and disappears 

 only at length, by the dilution which accompanies the growth. It is then easy to 

 see how the part near the rootmeristem grows the most rapidly whilst the region of the 

 roothairs grows no more at all. 



That the pigment, without killing the cells, has penetrated into the inner part 

 of the tissues, is not only shown by the germeroots, but also by the coloured spots of 

 the seedlobes, whose phloembundles even have taken up the colour.
