Furthermore, it forms a perfectpacking by entering the grooves C (as seen infig. 2,) and forcing itself around the groovehead D, a small quantity of it will secret it-self under the gates and pass into the groovesB B, fig. 2, and will be forced around the edgesof the gates by the steam so soon as the gatesrise. Being thus provided with a packing,the cap, (a section of which is seen at D ,) need not set so close on the wheel as tobind orcause friction. The liquid escapes atK, and falls into a receiver below, from whichit is again taken up by pump L L, and de-posited into the box H H, through a funnelstrainer M. N, the frame on which thewheel rests.

It is stated, in a letter from Naples, that theancient amphitheatre of Pouz/.oles has beenfreed from the earth that surrounded it, andmay now be examined in all its parts.
