the Committee. The late Sir Robert Christison at almost every 
meeting reiterated the same wish. 
The Convener of the Committee has made an attempt to carry out 
these suggestions, by gathering out of the seven reports already 
published, all the facts, applicable to the respective counties, in 
alphabetical order. 
The compendium is such that any one wishing to learn something 
of the boulders in any particular county, or parish of that county 
(in so far as reported to the Committee), will be at once able to get 
that information. 
But besides a topographical abstract merely to show where boulders 
of all kinds occur, one of perhaps greater interest might be formed, 
classifying boulders, under such heads as the following, and indicat- 
ing the reports where they are noticed : — ( 1 ) Boulders of great size 
or weight : — (2) boulders perched on peaks or summits of hills ; (3) 
boulders at very high levels above the sea ; (4) boulders on islands 
remote from any mainland ; ( 5 ) boulder transport in so far as 
indicated by the ascertained direction of parent rock, or by the 
bearing of longer axis of boulders, or by the direction and depth of 
striae on their surfaces. 
Another heading in such an abstract, might be a reference to 
localities where great accumulations of sand and gravel occur, 
whether in the form of mounds, or embankments, or of horizontal 
terraces, and at various heights above the sea ; for notices of these 
occur in several of the reports.
