series of diagrams the new partitions, or those just about to form, are in each case outlined; and in the next succeeding stage they are shewn after settling down into position, and after exercising their respective tractions on the walls previously laid down. It is clear, I think, that these four diagrammatic figures represent all that is shewn in the first five stages drawn by Berthold from the plant itself; but the corôÙreôÙsponôÙdence cannot {373} in this case be precisely accurate, for the simple reason that Bertholdãs figures are taken from different individuals, and are therefore only apôÙproxôÙiôÙmateôÙly consecutive and not strictly continuous. The last of the six drawings in Fig. 144 is already too
complicated for diagrammatisation, that is to say it is too complicated for us to decipher with certainty the precise order of appearance of the numerous partitions which it contains. But in Fig. 156 I shew one more diagrammatic figure, of a
