POPULAR SCIENCE REVIEW. 
the supply of microscopes was most liberal, comprising three of 
Hartnack’s pattern, four of Merz’s,one of Winkers (of Gottingen), 
a binocular by Smith and Beck, an instrument by Boss, one 
dissecting microscope by Zeiss, besides simple microscopes for 
dissecting, lenses, &c. Such instruments as forceps and scissors 
were plated with nickel, so as to guard against rust — that 
plague of all steel instruments, either on board ship or in hot 
climates. These are much to be recommended to all naturalists 
who work on the sea-coast.* 
Of the library the naturalists were not* a little proud, in- 
cluding as it does inter alia such splendid works as Bronn’s 
44 Klassen und Ordnungen des Thierreichs,” Milne-Ed wards’ 
44 Lepons sur la physiologie et Tanatomie comparee,” ten volumes 
of Petermann’s 44 Mittheilungen,” Siebold and Kodiker’s 
44 Zeitschrift,” Max Sehultze’s 44 Arehiv,” the 44 Transactions ” 
of the Linnsean and Zoological Societies, and some volumes of 
the 44 Philosophical Transactions,” together with such reprints 
of papers upon the development of marine animals as were the 
property of individual members of the staff- 
The naturalists spent their time generally in the laboratory, 
until they were hailed by the cry, 44 The dredge is up,” when 
they rushed on deck, each armed with a forceps, eager to explore 
the contents of the dredge or trawl. In some respects the 
trawl was found to be superior to the dredge, as this latter 
brings up so much mud as to spoil delicate organisms. 
For a week the Challenger experienced very bad weather in 
the Channel and in the Bay of Biscay, which, however, was 
even an advantage, as tending to find out weak points before 
that it was too late to remedy them. The ship rolls very much 
— over 35° 44 when put to it.” 
Off the coast of Portugal specimens of Hycdonema t and 
Euplectella ( 44 Venus’ Flower Basket”) were obtained with 
spicules not to be distinguished from those of their representa- 
tives in the Philippines. Some fishes were brought up from 
600 fathoms off Cape St. Vincent, which were in a peculiar 
condition from the expansion of the air in their bodies, on 
relief from extreme pressure, their eyes having a singular 
appearance, 44 protruding like globes from their heads.” From 
1,090 fathoms a gigantic Amphipod crustacean was brought up, 
of the family Hyperina , allied to Phronima . The eyes were very 
remarkable, 44 extending in two great facetted lobes over the 
whole of the anterior part of the cephalo-thorax,” like the eyes 
* They were made by Baker, of Holborn.

quoted, fig. 66, p. 421.
