Genetics and Cytology have, in the past twenty years, combined to place the chromosome in the important role of chief physical link between parent and offspring. Through this body the parent bequeaths its potentialities in the form of determiners which have been called genes. Any portion of an organism which has a function of such significance is obviously a subject for considerable investigation. The study of chromosomes is definitely a part of the somewhat wider study of cell processes. The phenomena of mitosis and cell division certainly involve changes in cell physiology and a knowledge of these changes may well be expected to throw some light on the more intimate nature of protoplasm. The study of chromosome structure, therefore, falls logically into its place as one of the many ramifications of the biologists' main problem, the establishment of the laws governing living matter. The problem of chromosome morphology is, therefore, of general biological significance. [...]
