THE study of life in the Sea andthe conditions there
,
prevailing has made very rapid advances within recent
Beyond “The Depths of the ‘OCean,” by Sir john
_
_
Murray and Professor johan Hjor_t, a.book suited rather '
,
'
to the needs of advanced students, there is no modern work
dealing in popular style with the science of oceanography
_
as
a
whole.
It is true there are many books covering ..
,
particular aspects of the subject and especially that fringe‘
_
_
of the" sea within the reach of all, the sea shore ; but the
\
latterdeà.l solely with the local fauna that surrounds our
_
shores and tell nothing about that world that lies stretching
'
Ï
for miles in all directions beyond the coasts, the open sea
"and oceans.
It is in” the hope of lling a gap in the litera—
- _
_
ture of natural history that these pages have been_wttenL
’
_
,
In preparing the book_the authors have each wtten_ those
'
Chapters dealing with subjects connected -With their Own
“
elds’of research.
It was thought that the ground Would“
,
,_
_be more fully covered inthis manner than if, all the Chapters
j
_
_
were
written in collaboration,’
