pleasant to the human mind; and the " pearl"—to which
the most precious object of human pursuit is likened by
its wisest guide/—derives its delightfulness merely from its
being of this perfect form, constructed of a substance of
lovely colour.
4. Then the second orders of arrangement are those in
which several beads or globes are associated in groups under
definite laws, of which of course the simplest is that they
should set themselves together as close as possible.
Take, therefore, eight marbles or beads ^ about three-
quarters of an inch in diameter; and place successively two,
three, four, etc., as near as they will go. You can but let
the first two touch, but the three will form a triangular
group, the four a square one, and so on, up to the octagon.
These are the first general types of all crystalline or in-
organic grouping: you must know their properties well;
and therefore you must draw them neatly.
5. Draw first the line an inch long, which you have
already practised/ and set upon it five dots, two large and
three small, dividing it into quarter inches,—A B, Plate III.
Then from the large dots as centres, through the small
ones, draw the two circles touching each other, as at C.
The triangle, equal-sided, each side half an inch, and
the square, in the same dimensions, with their dots, and
their groups of circles, are given in succession in the plate;
and you will proceed to draw the pentagon, hexagon, hep-
tagon, and octagon group, in the same manner, all of them
half an inch in the side. All to be done with the lead,
free hand, corrected by test of compasses till you get them
moderately right, and finally drawn over the lead with
common steel pen and ink.
* In St. George's schools, they are to be of pale rose-coloured or amber-
coloured quartz, with the prettiest veins I can find it bearing: there are
any quantity of tons of rich stone ready for us, waste on our beaches.
