or doctrine concerning it. On the contrary, it is indispensable 

 for us to be acquainted at the same time with all the organs 

 and viscera through which it circulates, as to their functions 

 and actions ; with the principles and elements of the physical 

 sciences, and with those pathological facts which make up our 

 knowledge of disease, or with the effects induced on the body 

 by disease. And not only so, but we ought likewise to keep in 

 remembrance the vicissitudes and changes of state which are 

 induced on the body by numberless external and internal in- 

 fluences, whether by climate, seasons, states of the weather; or 

 by diversities of food, medicines or the like ; or by passions of 

 the mind, which may be either in an orderly or disorderly 

 condition : — in short, the circuit of science in its widest range ; 

 its height and its depth, must all be searched, in order to arrive 

 at a complete knowledge and doctrine of the blood. 



It will not be difficult to discern, therefore, the reason of 

 our comparative ignorance, and of our real uncertainty con- 

 cerning its true nature ; for in proportion to the limited views 

 we take of this wonderful fluid will our means fail us of es- 

 caping from the labyrinthian windings of the subject, or of ex- 

 tricating ourselves from those difficulties respecting the nature 

 of life which the materialist delights in on the one hand, and 

 the mystic broods upon on the other. 



In our next lecture we shall proceed to consider the Flu- 

 idity and Vitality of the Blood.

LXXXIV. 071 the Geology of East Norfolk; with Remarks 

 upofi the Hypothesis of Mr. Robberds, respecting the former 

 Level of the Gcrmayi Ocean.By R. C. Taylor, Esq. F.G.S. 



[Concluded from page 353.] 



T^HE ground upon which the town of Yarmouth stands is 

 "*■ decidedly alluvial. Four distinct processes contributed to 

 its formation. The first may be traced in the accumulation of 

 heavy materials, rolled by the action of the sea ; the second 

 in the deposit of oozy sediment from muddy waters ; the third 

 in the external covering of sand by the operations of the winds; 

 and lastly, in the rise and decay of vegetable substances. 



The wind is a more powerful agent in forming the sandy 

 belts which defend our shores, than has been imagined. Mr. 

 Robberds has overlooked this circumstance altogether, in spe- 

 culating on the origin of the low lands between Caister and 

 Gorleston. His arguments are, that if the sea retained the 

 same level as when it washed up the banks across this asstu- 

 ar}', it would occasionally still overflow those mounds ; and
