Abstract

I AGREE with Miss Schafer1 that the use of a Greek letter for the basic chromosome number has serious disadvantages and should therefore be dropped. But I think a new symbol is necessary, to avoid the confusion which results from a resuscitation of x for this purpose. This symbol tends to be overworked, presumably because every schoolboy begins his algebra with x as the unknown quantity. In the result we have papers written on the effect of X-rays on the X-chromosome. In this case, however, no confusion results, because the two uses of X are so different.
