tation to the Crab's palate, and the pot is sunk in 

 deep water by means of a heavy stone. A line 

 attached to a float on the surface of the water, marks 

 the situation of each pot, and prevents mistakes as 

 to property. 



The Lobster is cauirht in the same manner as tlie 

 Crab, and both are in great demand for the delicacy 

 of their flesh. A very large proportion of those 

 eaten in England are brought from Norway. At first 

 there does not seem much in common in the form of 

 these two animals, except that both are furnished 

 with pincers ; but on examination, we shall find that 

 both are constructed on the same model. The shield 

 of the chest which was broad and flat in the Crab, is 

 long and arched in the Lobster ; and the belly, which 

 was thin, small, and folded out of sight, under tlie 

 body, is in the latter much larger, and though bent, 

 may be extended, and is terminated by fringed horny 

 plates like a fin : the antennae, or horn-like processes 

 of the heail, are veiy long. Thus we perceive, and 

 there are many other examples which might be ad- 

 duced, that it has pleased God to vaiy the forms of 

 created beings, not by making each on a separate and 

 independent plan, but by creating certain forms, 

 which are viewed as types or models, and vaiying the 

 parts, common to many species, in detail. The one 

 mode would have been as easy as the other ; there 

 can be no gradations of facility in creation to Omni- 

 potence ; but doubtless He had wise ends in view in 

 thus proceeding, tliough we may fail, from ignorance, 

 in discerning them. Probably one reason may have 

 been the formation of one harmonious whole out of
