Illustrating the distortion effect of lateral adhesion followed by me- chanical separation of the two chromosomes. Chromatic materials from the bands between a and a' in one chromosome have been drawn out at right angles to the chromosome in the form of strands, connecting with similar strands from the other chromosome, at b. Such distortion should reveal the presence of longitudinal " threads " within the chromosome if detectable chromonemata are present; but none appear..
