The analogy between glaciers and viscous bodies had been vaguely noticed by previous observers, such...

With that impartial superciliousness to all foreign achievement which not seldom characterizes the...

...Professor Forbes' own theory of glacier motion is therefore this: — a glacier is an imperfect fluid or viscous body, which is urged down slopes of a certain inclination by the natural pressure of its parts : — and he illustrates and explains this view by such a variety of...

Comparing that motion to the flow of a river, he propounded the theory that "a glacier is an imperfect fluid or a viscous body,...urged down slopes of a certain inclination by the nratual pressure of its parts." The observations and journeys which led him to this deduction are detailed...
