surveyed, when we have arrived at a point which we cannot pass it were folly and 

 presumption to imagine. That part of space beyond which the art and genius of man fail 

 to conduct his glance, simply reminds us that we are finite beings, and that we have 

 reached the limit which for the present circumscribes finite powers. It is not the boundary 

 of the Creator's workmanship, but a point of indication, that His house, to us, is, like 

 Himself, illimitable, and that its measurement is a' task to which His infinitude alone is 

 equal. 



With these notices, the view proposed to be taken of the SCENERY OF THE HEAVENS 

 concludes. It cannot close more appropriately than with the advice to Adam, which 

 Milton puts into the mouth of the angel : 



" Yet not to earth are those bright luminaries 

 Officious ; but to thee, earth's habitant, 

 And for the heaven's wide circuit, let it speak 

 The Maker's high magnificence ; who built 

 So spacious, and his line stretched out so far, 

 THAT MAN MAY KNOW HE DWELLS NOT IN HIS OWN ; 

 An edifice too large for him to fill, 

 Lodged in a small partition ; and the rest 

 Ordained for uses to his Lord best known."
