curving- the picture, or by mounting it in an instrument I 
have devised for the purpose, and which I propose to call a 
Pantascope or Orthoscope. In that instrument the curved 
picture and lens have a definite relation to the lens and camera 
employed, so that the images are seen exactly in situ, and if 
for the lens we substituted a theodilite or similar instrument, 
the horizontal bearings of each object could be taken as in 
nature. As only a narrow strip of the field is employed, the 
view is free from the distortion which we should have had 
with the same lens covering a large field. 
It will be seen, on examining pictures in this instrument, 
that from the fact of the lens being thus truly placed we have 
on looking through it such admirable light and shade, and 
such perfect modelling of the objects, that the effect is artistic 
relief in the highest degree, almost in fact competing with the 
solidity due to binocular vision. As the lens magnifies the 
objects considerably, beautiful detail is obtained, the geologi- 
cal character of the distant rocks and the peculiar character of 
the ice of the glaciers being represented with most striking 
effect. 
These views have been shown to the Alpine Club and to 
Professor Forbes of Edinburgh, whose labours on the glaciers 
are so well known. All concur in considering them the most 
perfect representations of the subject which have been yet 
produced. 
Mr. Buxton said that he could add his testimony as to 
the amount of rough usage which a Pantascopic Camera 
would bear without Jbeing rendered unfit for work. The 
camera he had used last summer was terribly knocked about 
on its way from London, and afterwards in Scotland, but the 
machinery always worked as smoothly as he could desire.
