520 Revieics — Geological Survey — Summary of Progress. 



as the detailed stratigraphy of a country. Not only are the facts 

 connected with the former especially well known to the Surveyman, 

 V)ut they appeal peculiarly to the business mind of his employer, the 

 Britisher in general. But indeed, as it has been well said, not one 

 of us, if we are scientists at heart, can afford to ignore any branch 

 of our science, "even though it be conspicuously — and even 

 glaringly — useful." 



At the end of the work we have an Appendix, containing several 

 carefully prepared tables ; a general list of the Upland graptolites 

 collected by the Survey, showing the formations they characterize; 

 a general list of all the Upland fossils of other classes in the Survey 

 collections; a list of fossil species prepared by Mrs. Gray from her 

 fine Girvan collection ; comparative tables of fossils from the 

 Stinchar Series, the Balclatchie Beds and their equivalents, etc. ; 

 from the Wenlock-Ludlow formations ; and finally, a complete 

 bibliography. We have already referred to the many illustrations 

 collected together at the end of the book, but the absence of plates 

 of the characteristic forms of the group of the Radiolaria, which has 

 proved itself of such high import in the formation of perhaps the 

 most i-eniarkable of the Upland rock sheets, is much to be regretted. 



We have already pointed out how the field observations in the 

 revision of the Uplands were conjointly the work of Messrs. Peach 

 and Home, assisted by Mr. M'Connochie as fossil collector, I'he 

 graptolites were identified mainly by Mr. Peach, the various other 

 fossils were classified and arranged by him, and he also prepared all 

 the illustrative diagrams, sketch-plans, and sections. The exacting 

 task of arranging the materials and of writing almost the whole of 

 this most interesting volume has fallen to the share of Mr. Home, 

 and the Director General has edited the whole. 



The book is alive throughout with interest and enthusiasm, and 

 it is well abreast, if indeed it is not well in advance, of anything 

 yet done in this special department abroad. It is evident that the 

 authors have spared themselves neither time nor trouble to arrive 

 at correct results and conclusions. It affords another proof, if such 

 were needed, that zonal work is pi'obably destined to effect in the 

 history of geological research a revolution as great and an advance 

 as rapid as those brought about by the use of the microscope in 

 the history of biology. This volume does not mark the ch)se of 

 geological investigation in the Uplands. It marks rather its true 

 beginning. Chas. Lapwokth.

LAST year, in the Geological Magazine for July and August 

 (pp. 306 and 358), we drew attention to the first issue of this 

 " Summary of Progress," which was prefaced by a full history of 

 the origin of the Geological Survey and Museum of Practical 

 Geology. 



The present "Summary" gives a very detailed account of the 

 observations made in the field and in the palaeontological and
