SUPERSTITIONS AND THEIR SOURCES ' 7
The following passage from the "Faithful Lapidary" of Thomas Nicols,5
who wrote in the middle of the seventeenth century, illustrates the
prevailing opinion in England at that time as to the virtues of
precious stones :
Perfectionem effectue contineri in causa. But
it cannot truly be so spoken of gemms and pretious stones, the effects
of which, by Lapidists are said to be, the making of men rich and
eloquent, to preserve men from thunder and lightning, from plagues and
diseases, to move dreams, to procure sleep, to foretell things to come,

causes, can produce none other but naturall effects, such as are all

operations of hot and cold, and of all the first qualities, and all
such accidents as do arise from the commixtion of the first qualities:
such as are hardnesse, heavinesse, thicknesse, colour, and tast. These
all are the naturall faculties of gemms, and these are the known
effects of the union of their matter, and of the operation of the first
qualities one upon another.
The
long-continued concentration of vision on an object tends to produce a
partial paralysis of certain functions of the brain. This effect may be
noted in the helplessness of a bird when its gaze is fixed upon the
glittering eyes of a serpent, or in the unwilling obedience yielded by
a lion or some other wild animal when forced to look into the intent
eyes of its trainer. In the same way those who gaze for a long time and
