In looking back over the career of this vast enterprise, so happily 

 originated and carried out, the consideration which most strongly im- 

 presses itself upon the mind is its unprecedented popularity. As an 

 illustration of this, it is stated, that in the month of May, 734,782 

 visits were paid to the building ; in June, 1,133,116 ; in July, 1,314,- 

 176 ; in August, 1,023,435 ; in September, 1,155,240 ; and in the first 

 11 days of October, 841,107. These figures give a total of 6,201,856, 

 as the sum of visits to the Exhibition. The greatest number of persons 

 ascertained to have been in the building at any one tune was on the 

 7th of October, wlien 93,224 were present. On the same day the num-

 amount of expenditure, from the commencement of the Exhibition to its

 of the Exhibition, from subscriptions at the commencement and from 

 fees of entrance, were 469,115 ; leaving a large balance in the hands 

 of the Commissioners. 



Curiosities of the Great Industrial Exhibition. In the Spanish De-

 made of rich, ivory-like, white wood, into which were inlaid designs of 

 extraordinary beauty, composed of small quadricules of colored woods. 

 These are so minute that it is necessary to examine the work through 

 a powerful magnifying glass before one can have any idea of the won- 

 derful delicacy of this monument of human ingenuity and patience. In 

 the wreaths, scrolls, and other ornaments which cover the top and the 

 shaft, there are three millions of these tiny cubes ; the arms of England 

 alone, which occupy a space only of three inches by two, containing
