158 Mr. J. Phillips on the Direction 



The structure of some other parenchymatous parts appears 

 equally indeterminate, presenting neither globule nor fibre. 



Pus. — As far as we have yet examined this secretion, its 

 particles appear to be as irregular in size and figure as those 

 observed in the brain, and bear no resemblance to those of 

 the blood. 



Milk. — In this fluid the particles appear to be perfect glo- 

 bules. But, far from being uniform, they present the most re- 

 markable varieties in respect to size. Whilst some are more 

 than double, others are not a tenth part of the size of the par- 

 ticles of the blood, to which they bear no resemblance. 



I forbear at present offering any remarks which the pre- 

 ceding observations would suggest. 



XXVII. On the Direction of the DiluvialCurrents inYoi'kshire. 

 5j/ John Phillips, M.Y.P.S. Lecttirer on Geology*. 



IVTR. WILLIAM SMITH has been represented by Mr. 

 '^"-*- Greenough as favouring the opinion that in our island 

 the waters of the deluge moved generally from east to west. 

 Mr. Smith, I believe, when he used these expi'essions in con- 

 versation, had in view merely to explain the occurrence of 

 chalk gravel in Warwickshire and Lincolnshire, and of chalk 

 flints on the oolite hills near Bath. 



Dr. Buckland, who in his ^^ ReliquicB Diluviance" has so 

 well expressed and enforced the general sentiments of English 

 geologists, as to be with justice regarded as the great advocate 

 and interpreter of the diluvial theory, has adduced evidence 

 by which he thinks he has made probable the opinion of a 

 general southward current. 



In the remarks which I have now to offer to the Society, it 

 is not my intention to travel over so wide a field. I rather wish 

 to confine my observations to some facts which I think tend 

 to show the direction of the diluvial waters across part of 

 Yorkshire, and of some neighbouring counties. For this object 

 I shall extract from my Journal some localities where boulders 

 have been seen of rocks so peculiarly characterized as to al- 

 low no doubt of the spots from whence they were dislodged. 



Shap and Birkbeck fells in Westmoreland, between Pen- 

 rith and Kendal, are elevated in some parts about 1500 feet 

 above the sea. Lying on the eastern skirts of the mountain
