Notes, Reviews and Comments. 211 



M. D., who, in 1873, published a smaller work dealing largely with the 

 same subject under the title " The Tourmaline." 



The present work, consisting of 72 pages, is divided into seven 

 chapters and illustrated with portraits of the author and his son (lately 

 deceased, and to whom, jointly with the author's father, the book is dedi- 

 cated), two views and two diagrams of the locality, and a series of 43 

 superb coloured plates of the wonderful tourmaline crystals which have 

 been found there. 



The subj.ct matter is divided into seven chapters, of which the 

 first five give a detailed account of the development of the locality from 

 the time of its accidental discovery by two young students, E. L. Hamlin 

 and E.Holmes in 1820, down to the present year; the sixth chapter gives a 

 description of ihe deposits and the occurence of the tourmalines etc., 

 with remarks on their forms and colours; and the seventh chapter explains 

 the various excavations which have been made and describes the colored 

 plates. 



Some of these plates represent restored crystals, but in these 

 instances outline plates are also given shewing the actual appearance of 

 the broken crystal. 



Scientists in general and mineralogists in particular owe a debt Of 

 gratitude to Mr. James A. Garland of New York, whose liberality, the 

 author tells us, has not only placed many of the choicest crystals of 

 tourmaline in the cabinet of Harvard University but has also rendered 

 possible the production of the superb coloured plates with which the 

 work is illustrated. 



As one who has repeatedly visited Mt. Mica, collected its wonder- 

 ful minerals, and enjoyed the privilege of examining many of the match, 

 less specimens described, the writer of the present notice can cordially 

 recommend this little book as most interesting and delightful reading, 

 dealing as it does with subjects which are of interest not only to the 

 mineralogist but to every lover of nature.
