that one part will remain attached to each chromosome. This 

 is also undoubtedly what takes place, as in the metaphase 

 when the chromosomes are all perfectly formed and placed on 

 the central spindle in the form of rings, we find that at the 

 center of one side of each ring is a globular body, frequently 



An auxocyte in the "bouquet stage." There are twelve leaders starting from five chromo- 

 plasts. The leaders consist of chromomeres containing chromioles suspended in a 

 film of chromoplasm. The spheres are of a foam-like structure. There are three acces- 

 sory archosomes and one archosome with two centrioles. The open space between the 

 inner granosphere and the outer plasmosphere represents the hyalosphere. The cytoplasm

containing one or more endochromatic granules. These bodies 

 attached to the chromosomes are, therefore, chromoplasts. In 

 the confluent umbrella stage the endochromatic granules are 

 the only indications of the presence of the chromoplasts. This 

 is the case in the auxocytes. In the spermatocytes the chro- 

 moplasts are much more difficult to follow, but the greater
