Bd. III: 2 ) CONTRIBUTIONS TO THE GEOLOGY OF THE FALKLAND ISLANDS. 3 
Louis, 30 km. NW of Stanley Harbour; my principal work during the stay in 
Port Louis was to survey the large stone-river S. of Berkeley Sound. 
When passing along the south coast of the Falkland Islands on the way from 
Port Stanley to Tierra del Fuego the Antarctic stopped in Port Albemarle for two 
days, during which I was enabled to visit a splendid coast-section at Cape Mere- 
dith that I had noticed on my earlier voyage along the coast. 
These were my opportunities of studying the geology of this island group, to 
our knowledge ot which I was able to add some new facts that will be related in 
the following pages. Some preliminary notes on my observations have already 
appeared,^ and Prof. Nathorst has published a paper on the plant-remains from 
Speedwell Island.^ 
The value of my geological observations in the Falkland Islands has been 
reduced by two accidents; the specimens from Cape Meredith were lost with 
the Antarctic, and some cases with collections from Port Louis, which had been 
deposited in Port Stanley, were broken up during our prolonged absence in the 
South and many of the specimens were carried away. 
The present paper is written principally as a guide for my friend T. G:SON 
Halle, who in accordance with my proposal has gone out to the Falkland Islands 
and to Tierra del Fuego in order to carry on — starting from my fragmentary 
observations — the geological exploration of these lands. 
I will use this opportunity of rendering my thanks to the Falkland Island 
Company, especially to two gentlemen in that company’s service, Mr. Harding and 
Mr. Girling, to Mr. Hennah in Port Stephens, to Mr. FIURST, then in Fox Bay, 
and to Mr. Packe in Port Stanley, who all assisted me in a most cordial manner. 
I am also much indebted to Dr. Selim Birger, who brought home very care- 
fully the collections that w’e had deposited in Port Stanley, and who has kindly 
placed at my disposal for use in this article some photographs from the vicinity of 
Stanley Harbour. 
The leader of our expedition. Prof. NordenskjÖld, has wdth unwearying readi- 
ness made the microscopical examination of the diabases. 
Prof. KaySER in Marburg has rendered me the valuable assistance of examining 
preliminarily the marine Devonian fossils, which have been handed to Dr. Fr. Dre- 
VERMANN in Frankfurt a. M. for a definite description. Prof. Nathorst has described 
the few plant-fossils^, and Dr. A. Atterberg in Kalmar has made the analysis 
of two specimens of »flowing soil». To all these gentlemen I wish to express my 
gratitude.
