The next customer that comes to be fitted with glasses can only see
the line marked XL on the distance card at 20 feet or about one-half
of what he should see, which leads you to think that there is no far
sight, for vision for distance is good except in very high degrees of
this error. Nor can there be old-sight, for vision for distance is
good in old-sight until after the fifty-fifth year, but it can be near
sight (myopia) or astigmatism, or both. We next try the near card and
find that even the finest line can be seen clearly if held
sufficiently close to the eyes. We now know that this is a case of
near sight, and we must fit them with glasses for distance. The
weakest concave that will enable him to see the line that should be
seen on the distance card at 20 feet is the proper one to give him for
use.--_The Optician._

CHARLES GOODYEAR.

CHARLES GOODYEAR was born in New Haven, December 29, 1800. He was the
son of Amasa Goodyear, and the eldest among six children. His father
was quite proud of being a descendant of Stephen Goodyear, one of the
founders of the colony of New Haven in 1638.
Amasa Goodyear owned a little farm on the neck of land in New Haven
which is now known as Oyster Point, and it was here that Charles spent
the earliest years of his life.
