This latter case is remarkable, as the electric fluid must have turned back at the acute angle of 26 degrees, to the line of its main course.

Besides the four tubes which I found vertical, and traced beneath the surface, there were several other groups of fragments, the original sites of which without doubt were near.

All occurred in a level area of shifting sand, sixty yards by twenty, situated among some high sand-hillocks, and at the distance of about half a mile from a chain of hills four or five hundred feet in height.

The most remarkable circumstance, as it appears to me, in this case as well as in that of Drigg, and in one described by M.Ribbentrop in Germany, is the number of tubes found within such limited spaces.
At Drigg, within an area of fifteen yards, three were observed, and the same number occurred in Germany.

In the case which I have described, certainly more than four existed within the space of the sixty by twenty yards.
