markably limpid and free from earthy impregnations. The inter- 

 sti'atification in the rusty brown sands of the white stone (detailed 

 sections of these beds will be given in Survey Memoir on Sheet 46), 

 on which the fuller's earth rests, may be due to the bleaching 

 properties of the fuller's earth with which it is in contact. The 

 Flitwick water comes off peat lying in a valley cut down through the 

 Greensands to the underlying Oxford. There is an enormous quantity 

 of iron in the water (as the analysis shows), encrusting everything 

 over which it flows, and a tufaceous-looking deposit of bog iron ore is 

 being formed of some extent and thickness. A. G. Cameron,

JOHN FRANCIS CAMPBELL, F.G.S., &c, 



(lAIN ILEACh), of ISLAY. 



John Francis Campbell, of Islay, the bearer of a name well known 

 among geologists some years ago, was born in Edinburgh on the 

 29th December, 1821. He had high family connections on the side 

 of both parents — his father being cousin to the present Duke of 

 Argyll, and his mother, who died while he was still a youth, 

 being the Lady Ellinor Charteris, daughter of Francis, seventh 

 Earl of Wemyss. By birth he was heir to a large patrimonial 

 estate. This inheritance was, however, lost to him through adverse 

 circumstances shortly after he came of age ; and the magnanimous 

 spirit in which through life he bore this reverse of fortune gained 

 him the abiding esteem of the large circle of friends whose regard 

 h-is generosity of heart and many attractive qualities must in any 

 case have secured. 



When, on the death of his father, who several years before had 

 contracted a second marriage, he found himself at a comparatively 

 early age the head of the family, he did everything in his power 

 to promote the welfare of his step-mother and her children. In 

 the year 1855 he joined them in their newly-adopted home at 

 Niddry Lodge, Carapden Hill ; and, laying aside the study of the 

 law which he had for some years previously pursued, he found 

 occupation successively as Private Secretary to his chief, the Duke 

 of Argyll ; Secretary to the Board of Health, to the Mines Com- 

 mission, and to the Lighthouse Commission, — the two latter employ- 

 ments stimulating him in those studies of Geology and Solar Physics 

 which engaged his attention and effort even in the last years of his 

 life. During the years 1861-1880 inclusive he held in succession 

 two posts in the Queen's Household. Having withdrawn from the 

 Court at the latter date, he afterwards occupied himself till the close 

 of his life with scientific study, travelling, and the social life of his 

 home. 



His many journeys in former vacations had taken him spvernl 

 times into Iceland and Scandinavia. On one occasion (187o-74) 

 he passed from Archangel through Eussia to the Caucasus, returning
