A VISIT TO THE NORTHERNMOST FOREST OF CHILE. 
By Pror, Fsprrico Parippr : 
Wuen I arrived aa nearly thirty years ago, I knew the plants 
of the desert of Atacama better than those of the central and 
of Val divia, where I passed many years, studying the flora as much 
as ny time allowed, and it was not until last year I could follow 
my wishes = visit the ts of Coquim 
I started with my son the stuffer of the museum on the 
17th of ante 1888, at 8 ry ere in the evening, in the steamer 
‘Serena,’ for the port of Coquimbo. The voyage was of no interest, 
— eather fine and clear, so that we could see the coast perfectly 
ong 
Leugua d suis in front of the bay of Tongoh, | in which 
end we sai ae ee houses of the little city of Tongoi, the port
