A day's microscopic shore-hunting. 75 



when it is, it is altogether insignificant compared with the one on 

 the fourth joint of A tax. 



In Fig. 20, Hygrobaks, there will be perceived a projection on 

 the second joint, which is altogether absent in any of the other 

 figures ; a careful study of these figures will, I think, be a great 

 help to the student commencing the study of the Hygrobatides.

IT is of great importance to study the living appearance and 

 surroundings of any subject of investigation, as errors are 

 frequently made and false conclusions arrived at, when we 

 have only the dead specimen before us, and knownothing of its 

 proper habitat, or of its appearance when in the full vigour of life. 

 This being the case, all microscopic naturalists should endea- 

 vour to do some practical collecting occasionally, in whatever 

 branch of study they may be working, for although it is often 

 nmch sterner work than is generally supposed, still it is of great 

 value, not only for the reasons already given, but also as supplying 

 a recreation, beneficial alike to mind and body. 



Few spots are more favourable for shore-hunting, or richer in 

 specimens of marine zoology, than the coasts of the Channel 

 Islands ; specimens which are of great rarity on our own shores 

 are often abundant here, and in some favoured nooks the quantity 

 of life is marvellous. 



Jersey is chiefly composed of Syenites, Basalts, Diorites, etc. 

 Many parts of its coast-line are high and precipitous, espe- 

 cially in the northern part of the island ; towards the French 

 coast, however, it is comparatively low and shelving, so that at low 

 water many thousand acres of rock are uncovered, whereas in the 

 former the base of the Syenite cliff is never exposed.
