to a microscojiic c.xaininatioii l>y the naturalists. Notes concerning these 
collections were always entered in the journals stating the general character of the fauna 
and flora, along with particulars about rare or unusual occurrences. Many hundreds of 
inicn>sco})ic preparations of these pelagic organisms were mounted in various preserving 
mediuni.s. 'Phe reports of Professor Haeckel ajid Mr Brady concerning the pelagic 
Kadiolaria and Foraminifera were largely based upon the microscopic preparations thus 
mounted during the voyage by Mr Murray. Samples of these tow-net gatherings were 
:dso preserved in spirit, but no systematic attempt was made to form complete collections 
of jielagic organisms rei)resenting each region of the ocean visited by the Expedition. 
To have preserved all the collections from the surface waters would have been beyond 
the resources at our command. Even those collections of pelagic organisms that were 
brought home were so large that they liave not yet all been carefully examined by 
specialists. 
When wc remember all the varied researches in which the Expedition was engaged, 
the wonder is that so much was accomplished, rather than that some fields of investigation 
were only partially explored.
