430 Obituary — Mr. J. Beete Jukes. 



deep coloured that the bed has been ground and used for paint. 

 The origin of this colour, whether due to original deposition, or 

 subsequently derived by segregation from the bed below, is a point 

 of interest. 



Above the Eed Chalk succeeds another chalk bed about one foot 

 thick, supposed to be equivalent to the M aim rock of Sussex, con- 

 taining many branched sponges as Sjpongia paradoxica, with Avicula 

 gryphceoides, Kingena lima, and other species ; this is covered by other 

 beds of Chalk, of which the lowest, about two feet six inches thick, 

 is remarkable for the abundance of fragments of Inocerami dispersed 

 throughout it (with other fossils, as Tei: gracilis, T. semiglobosa, and 

 Holaster planus), and which give it a very irregular surface when 

 weathered. By the inclination of the strata before noticed, these 

 latter beds come to the shore at the north end of the cliff. The 

 trend of the coast, partly modified by an angular projection, does not 

 exactly coincide with the direction of the dip, which is very slight 

 towards the north-east. It is to this arrangement, (due to some 

 original movement and subsequent denudation), that the strata succes- 

 sively crop out in a south-easterly direction, and the general form of 

 the country has been produced. The face of the cliff varies con- 

 tinually, owing to the falls which frequently take place, a consider- 

 able one having lately occurred, so that during the last fifty or sixty 

 years many acres have been removed, owing to the action of the sea 

 against the cliff, together with the effects of rain and frost on the 

 adjacent surface of the land. 



Altogether this section is interesting to the geological student, not 

 only as showing the nature of these old sea-beds, their mode of accu- 

 mulation, the effects of currents, and the difference of condition, 

 when compared with other areas of contemporary deposition, but 

 the modifications they have subsequently undergone by chemical 

 and other agencies, and the general effects of the later operations in 

 producing the surface features of the country.

The late Pkofessok J. Beete Jukes, M.A., F.E.S., etc. — It is 

 our melancholy task to record the death of one of the most dis- 

 tinguished students of Natural History — a pioneer in Geological 

 Science — an undaunted investigator of the truths of Nature. We 

 can recall the massive form, the penetrating glance, and sturdy step 

 of our late friend, as many years ago we accompanied him amongst 

 the mountains of North Wales, and had the advantage of his instruc- 

 tion when attempting to unravel the intricate structure of their rocks. 

 How hard it is to realise that that head is now laid at rest in a 

 quiet churchyard of central England ! As a last tribute of respect to 

 his memory, and in grateful remembrance of many acts of kindness, 

 we venture to place on record the following short account of the late 

 Mr. Jukes' eventful life. 



J. Beete Jukes was born near Birmingham on the 10th of October, 

 1811, and educated at King Edwards' School in that town, whence
