worked very well. During the first few months of the Expedition a few specimens may, 
from insufficient arrangements, have been destroyed, but as the naturalists became more 
accustomed to work on board ship, hardly a specimen from any of the deep-sea stations 
was lost or misplaced. Doubtless some of the smaller forms and parasites may have 
escaped observation when the trawl came in late in the evening, or when the weather did 
not permit careful examination, and some delicate fishes and invertebrates from deep 
water were mutilated beyond identification ; but with these exceptions, the foregoing 
lists of the organisms taken in the deep-water trawlings and dredgings may be regarded 
as a complete record of all the species captured, with the exception of the Protozoa. In 
the early part of the cruise small samples only of the deposits were preserved, from the 
belief that the quantity brought up was much greater than would be required for any 
scientific purpose ; all the deposit in the trawl or dredge was, however, passed through 
sieves before being thrown away, and the larger particles thus procured were preserved. 
In the later years of the voyage much larger quantities of the deposits were preserved 
and brought home. 
At almost every place where the ship came to anchor extensive collections of marine 
animals were made by trawlings and dredgings from the steam pinnace in shallow water. 
These collections were made use of by the naturalists for their own study and information, 
but only mere fractions of them were preserved, with the exception of collections made 
on a few remote or rarely visited coasts. This accounts for the rather meagre lists Shore and 
of shallow-water marine animals recorded at many places visited by the Expedition, 
especially during the early part of the voyage. It was thought that the extensive 
preservation of shallow-water marine specimens might seriously interfere with the more 
important investigations of the deep sea, which were rightly regarded as the special and 
proper sphere of our labours. Even on board the Challenger there was a limit to the 
number of specimen-bottles, the quantity of spirit for the preservation of specimens, 
and of space for storage. Still, with a little arrangement before-hand, many valuable 
collections might have been dispatched direct to Great Britain without necessarily 
hampering the peculiar researches for the prosecution of which the Expedition was 
organised, and the national collections might in this way have been greatly enriched by 
many excellent collections and new species of organisms from distant parts of the world. 
The tow-nets made of bunting, fine cotton cloth, gauze or silk, were continually 
dragged through the surface and sub-surface waters of the ocean, and were frequently sent 
to great depths. Very many separate collections of pelagic organisms were made in this 
way during a single day when the conditions were favourable, and these were at the time
