centre, which keeps contracting under the pressure due to the curvature 

 of its limb. 



Set 5. 



Thus as the centre contracts the arm increases in length. 



This increase in length causes, after a certain point, a tendency to 

 split into drops. This tendency is counteracted by the thickening of 

 the cylinder from the injection of liquid at the inner end. 



Set 6. 



This thickening gives efficiency to the curvature of the end of the 

 cylinder, and the arm contracts slowly. 



Set 7. 



This accounts for our seeing arms whose length is very great compared 

 with their diameter, but which do not succeed in splitting into drops.
