himself, occasionally arrived at conclusions different in many 
respects from those reached by his more steady-going con- 
temporaries. Still, although one could not always agree 
with him in the views that he had thought out for himself, 
his conclusions always repaid attentive consideration. They 
not only possessed the charm of originality, but they were, 
almost always, good broad generalisations, which, if not in 
every case sound, yet enabled those who grasped them to 
take a wider, better, and more comprehensive view of the 
subject to which they happened to relate. 
During the last five or six years his attention had been 
much attracted by the discoveries relating to the geological 
structure of the north-west Highlands of Scotland, which 
have formed the subject of various communications by 
Professor Lapworth and the working staff of the Geological 
Survey of Scotland. Many people with good brains fail even 
now to grasp the full meaning of the complicated structures 
referred to, but my geological friends who knew Mr Jenner 
will bear me out in the statement that this old man of eighty- 
four had got all the broader features of that marvellous piece 
of geological history thoroughly in mind. For this he was, it 
is true, largely indebted to the teaching of Professor Lapworth 
and Mr Peach themselves. 
From the geological history of Sutherland he turned his 
attention to that of the central Alps, with whose topography 
his travels had made him familiar. One of the last visits I 
paid to the house was for the purpose of discussing with him 
some of the more interesting passages relating to the geology 
of the Alps in Heim’s “ Mechanismus der Gebirgbildung,” of 
which book he was particularly fond. 
Although Mr Jenner latterly did but little original 
scientific work himself, yet both individuals and societies 
engaged in research ever found in him a warm and helpful 
friend.
