,, ^ ese engravings represent an elevation and sections of6 peculiar arrangements adopted in these smeltingworks. Fig. 1 represents the section of the chimney■with the flue entering it from below. Fig. 2 shows thearrangement adopted for deprecating the fumes as theyP? 5 ® upwards, and also the hydraulic trap at the summito,t *'U e vertical flue of the exhausting chamber. Fig. 3shows the mechanical arrangement for communicating areciprocating horizontal movement to the hydraulic slideplate over the top of the chamber. Fig. 4 shows the

slide plate seen from above. Fig. 5 is a ground plan ofthe chambers, chimney, &c.

The following illustrations accompany the model.

A block of pure silver, weighing more than 140 lbs.;separated from the rich lead, and purchased by silver-smiths as “ unalloyed.”
