CLOCK.

Plate CXLVI.

Fig. 3. A detailed drawing of a clock face. It features a large outer dial with Roman numerals (II, III, IV, V, VI, VII, VIII, IX, X, XI, XII) and minute markings. Inside this is a smaller dial with Arabic numerals (1-12). At the top, there is a small circular dial with a scale from 0 to 60 and a needle labeled 'B'. The entire clock is housed in a dark, arched wooden case.

PLATE III

Technical drawing of a mechanical device, possibly a press or loom, with various gears and levers.A detailed technical drawing of a mechanical apparatus, likely a textile loom or a similar industrial machine. It features a complex arrangement of gears, levers, and a large horizontal frame. The drawing is rendered in a fine-lined, engraved style.
Technical drawing of a circular instrument, possibly a sundial or a specialized clock face, with concentric circles and a central pointer.A technical drawing of a circular instrument, possibly a sundial or a specialized clock face. It consists of several concentric circles. The outermost circle has a scale with markings. Inside, there are smaller circles and a central pointer or gnomon. The drawing is rendered in a fine-lined, engraved style.

Fig. 6.
Diagram of a mechanical component with three overlapping circles labeled A, B, and C. The top circle is labeled 'R' and 'D.C.' with '120' below it. The middle circle is labeled 'C' and 'R.C.' with '120' below it. The bottom circle is labeled 'A' and 'Valley' with '120' below it. Two vertical lines extend downwards from the bottom circle, labeled 'G' and 'G'.
Fig. 9.
Diagram of a mechanical component showing a vertical rod labeled 'G' passing through a horizontal bar labeled 'H'. The rod is pivoted at a point labeled 'D'. A horizontal arm extends from the pivot, ending in a small circle labeled 'P'. A large circle labeled 'A' is shown below the rod, with points 'B' and 'C' marked on its circumference. A small circle labeled 'M' is also present.
Fig. 8.
Diagram of a circular dial with Roman numerals. The dial has an outer ring with numbers 1-12 and an inner ring with numbers 1-24. A small circle labeled 'F' is in the center, and a small circle labeled 'V' is on the inner ring. A compass rose is shown to the left of the dial.

A large circular clock face with Roman numerals. The clock is mounted on a square frame. Above the clock is a circular vignette of a bridge with multiple arches. The clock face contains several concentric rings with text. The outermost ring has Roman numerals. The next ring has numbers 1-12. The third ring contains text: 'The Line of the Sun's Declination and Time of High Water at London B.' and 'The Moon's Age' and 'The Moon's Light'. The innermost ring is a grid. A long hand points to approximately 10:10.
Faint circular seal or emblem with radiating lines.A faint, circular emblem or seal is centered on the page. It features a central circle surrounded by a ring of radiating lines, resembling a sunburst or a gear. The entire emblem is rendered in a light, translucent grey, suggesting it is a watermark or a faded stamp. The background of the page is a light beige with some minor discoloration and small spots.
