MARINE BIOLOGICAL STATION AT PORT ERIN. 49 
_ Survey were published in a series of six volumes (Edinburgh, 
1910), edited by Sir John Murray and Mr. Lawrence Pullar, 
and dedicated to the memory of Mr. F. P. Pullar, who had 
done much to initiate and promote the investigation in its 
- earlier stages. 
The work dealt with the determination of the depths of 
the lakes and of the general form of the basins they occupy, 
_ along with observations in other branches of limnography 
_ from the topographical, geological, physical, chemical and 
biological points of view. Some important novel investigations, 
such as those on the temperature seiche and variations in the 
viscosity of the water with temperature, help to throw light on 
some oceanographical problems. In fact, the whole investiga- 
tion, containing 60,000 soundings taken in 562 lakes, resulted 
in very substantial contributions to knowledge, and is probably 
the most complete account of the depths and other physical 
features of lakes that has been published in any country. 
It cannot be said that Murray ever finished his work on 
the West Coast of Scotland, and I have evidence in a letter 
that he wrote to me late in life that he still thought of returning 
to the work. The passage is worth quoting, both for its scientific 
interest and for the kindly consideration which it shows. It 
is dated 20th May, 1913, less than a year before his death :— 
9) I am seriously thinking of overhauling all 
the ‘Medusa’ work on the West Coast, and repeating a lot 
of these old observations for two years or more; then pub- 
lishing a book on the lochs of the West Coast. Would that 
_ in any way interfere with your work? I am being pressed by 
the Clyde people to do something of the kind.

During the years when he was working at the “ Challenger ” 
results and subsequently, Murray published many papers in 
the Geographical Journal and in the Scottish Geographical
