“The church of La Morceda, at Valparaiso, built of burnt bricks, 
stood with its length north and south. [The houses are built of adobes, 
or sun-dried bricks.] ‘The church tower; sixty feet high, was lev- 
eled ; the two side walls, full of rents, were left. standing, supporting 
part of the shattered roof, but the two end-walls were entirely demol- 
ished. On each side of the church were four massive buttresses, six 
feet square, of good brickwork ; those on the western side were thrown 
down and broken to pieces, as were two on the eastern side. The 
other two were twisted off from the wall in a northeasterly direction, 
and left standing.’ The direction of the. shocks was thought to be 
either from the southwest, or from the northwest. 
“The last instance I shall quote is from the pages of the able and 
delightful Darwin, in his Journal of a Naturalist’s Voyage, (Colonial 
Library, edit. p. 308), in describing the effects of the great earthquake 
of March, 1835, upon the buildings in the town of Conception; and 
after noticing also the evidences of immense velocity in the shock, by 
which the projecting buttresses from the nave walls of the cathedral 
had been cut clean off close to the wall, by their own inertia, while the 
wall, which was in the line of shock, remained standing ; he proceeds, 
~—‘Some square ornaments on the coping of these same walls were 
moved by the earthquake into a diagonal position. A similar circum- 
stance was observed after an earthquake at Valparaiso, Calabria and 
other places, including some of the ancient Greek temples’ (for which 
he quotes 5 in a omni bes oar gs scare ngs a

9. Geological Chart of M. Boué; (Bull. de Ia’ Soe: Geol, he. Frail 
2 Ser., i, 572.)—The fine large geological chart by Boué embraces a 
general view of the geology of the globe, and was published under the 
auspices of the Geological Society of —, The following results 
appear to be established by it: - 
-1.-The more ancient formations prevail towards the poles, in the 
principal ossature near the equator, and around the great ocean. 
2. The intermediary (Silurian) formations exist‘about the poles and 
in the northern temperate zone. But they fail almost entirely under 
the equator. 23 
3. The secondary formations rest in the concayities of the interme- 
diary formations in the northern hemisphere, whilst rat rest upon ' = 
primary of the equator. ~ 
4. The tertiary abound near rie equatety ; they fill the lowest oath 
of the basins of the sea, and form a zone extending from the Desert of
