ball will roll rapidly upon its surface, and
yet have such pattern produce the irregu
lar form desired.
Second, 10 have the cutting point so sen.
sitive to the motions Of the tracing ball up

Third, To be allie 70 transfer the design

Fourth to adopt The mechanism Of tha

from the original work Of art.
Fifth, To combine tie solution Of the
above four mechanical roblems in sim
