following year, received. About one half of these answers supplied 
information, which gave materials for the two first Keports. Most 
of these answers were useful also, by indicating the localities of 
remarkable Boulders, and thus enabling members of the Com- 
mittee to visit them. 
In recording the information from time to time obtained, the 
Committee could do no more in preparing the Annual Eeports than 
mention the particular county where the Boulder was reported 
to be situated. The consequence is, if any one wishes to discover 
what or where are the Boulders, described as occurring in any 
particular county, he must hunt through the whole nine Annual 
Reports to obtain this knowledge. 
In order to remove this inconvenience, the Committee have 
framed a compendium or abstract of the whole information in these 
Reports, so as to represent for each county, in alphabetical order, 
what is said in them regarding Boulders. This abstract will be 
found in Appendix I. 
In addition to a geographical arrangement of the information 
contained in the Annual Reports, it occurred to some members 
of the Committee, that it would be useful to have a Summary of 
the most material facts found in the Reports, and of the inferences 
which these facts suggest, in so far as they seem to throw light 
on the question, by what agency Boulders could have been trans- 
ported. Such a Summary has been undertaken by the Convener, 
and it forms Appendix No. II. This Summary consists almost 
entirely of the facts set forth in the Annual Reports and in 
Appendix I. ; but the inferences from these facts involve opinions 
in which all persons may not agree. Therefore the Committee 
do not commit themselves either to the adoption or to the rejection 
of these opinions, though they quite allow that they are valuable as 
indicating points worthy of consideration. 
The Committee, whilst aware that their business was to investi- 
gate the subject of Scotch Boulders, have not deemed it any 
departure from the objects of their appointment to advert to well 
authenticated cases of Boulders situated in English counties, which 
have been on good grounds traced to parent rocks in the south of 
Scotland {Abstract^ pp. 796, 797, 838, and 852).
