fiftli larger. But the true rival will probably bo tliougbt to be 

 the Hyde Park Paxton BiiilJing, now erecting at Sydenham. 

 That building was 1,848 feet long, by 408 feet broad, thus giv- 

 ing, on the ground floor, seven hundred and fifty-three thousand 

 nine hundred and eighty-four square feet, and, with the transept, 

 eighteen acres. This building covers only one-eighth of the 

 ground occupied by the Hyde Park monster, but the available 

 space, with the galleries, is about one-fifth or one sixth. But it 

 is plain enough that, independent of the question where so large 

 a building as the Paxton Palace should or could be put, it would 



be very absurd to erect one here of such gigantic dimensions. 

 The Atlantic is not yet quite abolished, and the business of 

 crossing the ocean, to fill the building with goods woilhy to be 

 exhibited, would be a good deal more serious than crossing the 

 English Channel. The New York Crystal Palace is large 

 enough for every purpose, in all conscience. As to the architec- 

 tural eifeet and beauty of the building, there will be no sort of 

 comparison. The general idea of the Reservoir square building 

 — that of a Greek cross with a dome over the centre — though 

 not by any means new, is one of approved architectural effect.

The column headed "Magnet" is an attempt to dislinffuish the character 

 of each day, as regards the frequency or extent of the fluctuations of the 

 Magnetic declination, indicated liy the self-registering instruments at Toronto. 

 The classification is, to some extent, arbitrary, and may require future 

 niodificatioDj but has been found tolerably definite as far as applied. It is as 

 follows : — 



(a) A marked absence of Magnelical disturbance. 



lb) Unimportant movements, not to be called disturbance. 



(r) Marked disturbance — wiiellier shewn by frequency or amount of 

 devialion from the norma! curve — but of no great importance. 



{(1) A grea(er degree of disturl>ance — but not of long continuance. 



((') Considerable disturbance — lasting more or less the whole day. 



(/) A Magnetical disturbance of the first class. 



The day is reckoned from noon to noon. II two letters are placed, the first 

 applies to the earlier, the latter to the later part of the trace. Although the 

 Declination is particularly referred to, it rarely happens that the same terms 

 are not applicable to the changes of tire Horizontal Force also.
