the metaniOrphic region lying toward Guyana TO the
south OF the Amazonas found the same succession
OF a paleozOc basin OF which can distinctly make
the three divisions oiurap, Devonan and Carbonf-
erOus the latter consequence OF its superpositon
exposing tie largest surface area.
The main portion Of Brazil made of metamorphic
rocks which also form most OF the coast line,
and along the coast at intervals far south Bahia
contain very osserous Cretaceous basins The work OF
the Commission has greatly increased the knowledge OF
these regions and also those south Of Rio, where fossil
ferrous paleozoc rocks again found. In the prov
nce OF Sercipe found large tracts OF partly meta
morphosed deposits, supposed to be pal9ozoc. they
form large mountain range called labyana Coal was
found in three OF the southern provinces Its existence
there known before but its character and relations
had been determined II only In thin beds,
and is very impure containing much sulphur and yield

the miner The coast regions OF The southern provinces
contain very extensive shelf heaps differing entirely
character from those OF the north Of Brazil The gold
and diamond regions were examined IN many places,
and the result OF some OF the explorations IN tue g9d
rcn company OF Americans for the purpose OF working
of the mines An able photographer accompanied
OF parties in the field, and over 300 negatives,
mostly OF large size, testify 70 the faithful manner In
which he carried his part OF the work Many OF these
views were exhibited at the Philadelphia Exposition
two years ago.
The Falls OF Paulo Alfonso the river San Francisco,
the Niagara of Brazl, carefully examined,
mapped and pictured They very poorly known be-
fore, and the same be said OF the penal island,
called Fernando de Noronha, situated about 200
miles of Cape Rogue This island differs entirely
from the main land, being OF volcanic origin,
and furnishing splendid illustrations OF dy kes and oima-
tons OF basac columns, representing on small scale
the Giants Causeway and FngaPs Cave, In Ireland.
In testimony OF the different explorations above emu

Janeiro 1t occupies large threestory building which
il fills from top bottom and its contents arranged
in complete systematic laboratory style. Twelve hund
red large trays hold the fossils rock specimens and an
tiquites which together take mp fourl large -Four
rooms also flied by the reef specimens consisting OF
an immense collection of dried cOras, and large Alec
hOlic collections OF general invertebrates and hsbes
Then the chemical and Photographic laboratories,
which the latter OF the largest IN Rio. General
work rooms make up the rest OF the building A
large series OF of antiquities had been made for
exchanging with foreign societies. but as yet they remain
unused.
The most OF the field reports ready for publica-

Southern Provinces. also all the descriptions Of paleo
zoc fossils and many Of the Cretsceous well those
of large share OF the antiquities. At the time OF his
death Professor HART was Just beginning 10 publish
these reports, and in the hope Of issuing much
printed work this Spring He has not lived 10 see the
good of Bis labOTs but he has left behind bin monument
