 at the opposite end ; c is a chain of cells, c' is the same three-quarters of 

 an hour later ; the lowest bud had, like those above it, assumed the typical 

 form of the species, but in the figure it is seen from the end, so that 

 its longitudinal axis is at right angles to the plane of the paper ; d d", 

 development during 1| hours ; '", during 2 hours ; //"", during 

 3 hours ; in ef, it is seen that the oval cells first develop a bud and
