Additional comments
Abstract
My initial comments applied to Dr. Hsieh's original
paper. His reply contains an additional assumption not
made previously; namely, that the vortex always consists
of the same fluid particles. Also, he now considers
a fixed region in the vicinity of the center, rather than
following a "fictitious point at the surface moving so
as to remain directly under the center of the upper
vortex." In view of these changes, it appears desirable
to add a few remarks.
