In the series of chapters of which the present is the first, I purpose to submit the results of an analytical examination of all the minerals of Scotland whose composition appeared doubtful; of such as had not previously been examined; or of such as appeared in any way to be of special geologic interest.
page 498 note * Incorrectly entered as Ankerite in Greg and Lettsom's “ British Minerals,” on the writer's authority.
page 504 note * Bineau says it is soluble in 62,500 parts of water—Peligot in 50,000 parts.
page 504 note † Fourcray says in 2504 parts.
page 506 note * The geologic bearings of so great a shrinkage, or cariousness of a previously solid stratum, being the direct consequence of dolomitization, must be apparent.
page 507 note * From which the calculated angles and specific gravities before given have been derived.
page 507 note † Being desirous to test the law more fully, the writer bethought him of a collection procured by the late Professor Jameson, and which is thus referred to at page 42 of the English edition of Bischof's “ Chemical Geology.” “ This petrifaction is in the Edinburgh Museum of Natural History. Professor Jameson commissioned Dr Krantz of Bonn to collect the most important minerals, pseudomorphs, &c., which are mentioned in the German edition of this work. I have closely examined this collection, which consists of 664 specimens, and have found many which illustrate the phenomena described much more clearly than the minerals which I used. I shall, therefore, frequently take occasion to refer to especially characteristic specimens in this collection.” Upon application being made to the Director of the Industrial Museum, all that could at first be found of this collection was the catalogue; though a certain number of specimens supposed to belong to it were afterwards seen:—it would appear that one of the results of the transference of the University collection has been the incorporation of this specially geologic collection with the mineralogic suite; where it is practically useless, and positively an eyesore. It is so far satisfactory to know that an attempt may be made by the Director to separate it.
