AN account OF the manner ct making very
fine threads Of glass is thus given in ii pa
per of science: GA fragment Of drawn-out
glass was attached by sealing wax to the
tail Of an arrow made of piece of straw
few inches in length: the glass was heated
to high temperature in the middle, ard
while the end was held i'll the fingers, the
arrow was projected by crossrbow of pine
held in q wise and with a trigger that could
be pulled by the foot. With every success
full shot the thread was continuous from
the piece held in hand to the arrow 50 feet
of, glass thread 90 feet long and one
thousandth of an inch in diameter be-
ing obtained. The diameter was almost
