KusANno saw and figured the clusters of small nuclei due to various 
sorts of amitosis as described in my former paper (5), but he did not 
study them carefully and failed to ascribe to them the importance 
that they really possess. He repeats the statement of his preliminary 
paper that the chromosomes number constantly five, and thus adds 
strongly to the case against the individuality of the chromosomes 
made in the present paper.
