ABSTRACT
The progress of experimental philosophy may be gathered, in a degree, from the perfection of the instruments it employs; for while it is certain that in some sciences much has been accomplished by the aid of rude and imperfect means, it is equally true that in others the perfection of the apparatus is essential to that of the knowledge sought to be established by deductions drawn from its indications. The large astronomical telescope in the Nave, mounted upon a stand, having equatorial movements and complete adjustments, is an interesting member of a Class. British manufacturers have for some time been making great efforts with a view of producing good optical glass, and a skilful method of working it into the forms desired for optical purposes. The musical instruments exhibited include several powerful organs. The organ over the Eastern Entrance exhibits a new and pleasing arrangement of pipes, and possesses a powerful set of stops.
