anchester they work and
construct machinery and tools of all kinds with differences in linear
measurements amounting to one ten-thousandth of an inch. The standards
of the English inch, etc., made by him for the Government--and now used
by all the engine and tool makers, etc., of the United Kingdom--lead to
the construction of machinery, etc., to such minute divisions; and the
adoption of these standards has already effected enormous saving to the
country by bringing all measured metal machinery, instruments, and
tools, wherever constructed and wherever afterwards applied and used, to
the same identical series of mathematical and precise gauges.

THE SABBATH, ETC. TYPIFIED IN THE PYRAMID.

The communication next discussed some others amongst the many and
diversified matters which Professor Smyth fancifully averred to be
typified and symbolised in the Great Pyramid.

One, for example, of the chambers in the Great Pyramid--the so-called
Queen's Chamber--has a roof composed of two large blocks of stone
leaning against each other, making a kind of slanting or double roof.
This double roof, and the four walls of the chamber count six, and
typify, according to Professor Smyth, the six days of the week, whilst
the floor counts, as it were, a seventh side to the room, "nobler and
more glorious than the rest," and typifying something, he conceives, of
a "nobler and more glorious order"--namely, the Sabbath; it is surely
difficult to fancy anything more strange than this strange idea.[272] In
forming this theory liberties are also confessedly taken with the floor
in order to make it duly larger than the other six sides of the room,
and to do so he theoretically lifts up the floor till it is placed
higher than the very entrance to the chamber; for originally the floor
and sides are otherwise too nearly alike in size to make a symbolic
_seven_-sided room with one of the sides proportionally and properly
larger than the other six sides. Yet Professor Smyth holds that, in the
above typical way, he has "shown," or indeed "proved entirely," that the
Sabbath had been heard of before Moses, and that thus he finds
unexpected and confirmatory light of a fact which, he avers, is of
"extraordinary importance, and possesses a ramifying influence through
many departments of religious life and progress."

He believes, also, that the corner-stone--so frequently alluded to by
the Psalmist and the Apostles as a symbol of the Messiah--is the h
