Reviews — Professor Jakes' School Manual. 275 



not of Jupiter; flabelUfer is " fan-bearer," not " fan-tail "; there is 

 no basis for the word "plant" in the etymology of " Stigmai-ia" 

 nor of " shell " in that of Terebratula, Producta, Gonintites, Galerites, 

 etc.; compttts means "neat" rather than "ornamented"; and grandis 

 "large" rather than "magnificent." Labyrinthodon, and other 

 names with a similar ending, are regarded as masculine (as indeed 

 is Mastodon in this book), and not neuter; " Cardium" is not really 

 "a heart"; " coranguhium" should be "snakes' (not snake's) heart," 

 — coranguinum, snake-heart, is better; and Ostrea (not Ostraa) is 

 correct. These and a few other such points should be attended to 

 for the sake of illiterate beginners. 



There is but little else to be found fault with : — perhaps, however, 

 we should note the carelessness of expression at p. 41 (repeated 

 from earlier editions), where the Esquimaux boat-poles, though 

 they have been moved inland, still remain beneath the sea. The 

 retention of " Plastic Clay " in place of " Woolwich and Beading 

 Beds," as also in former editions, has evidently escaped the Editor's 

 notice (p. 3-53). At page 362 the basalt of Antrim is referred to as 

 of Miocene age, but on the previous page it is placed among the 

 " Eocene Volcanic Bocks," being of the same age as those of Mull, 

 which have Eocene plants interstratified with them. This discovery 

 ought to have been credited to Mr. J. S. Gardner, as an important 

 correction of a former notion about the existence of Miocene beds 

 in the British Islands. 



The chapters on the Palaeozoic formations are much improved ; 

 but necessary succinctness has limited the subject very much. Still, 

 Wales ought not to have had its chief Coal-field put into the South of 

 England. The Ordovician and Cambrian are carefully distinguished 

 from the Silurian proper, and from the Pre-Cambrian and Archaean 

 rocks. The Cambrian Hymenocaris, however, ought not to be still 

 handed down with three front spikes (p. 240), which Mr. Salter 

 long ago did away with ; and the organic standing of Oldhamia, 

 having been doubted, cannot at present be dogmatically defined 

 (p. 231). 



Among the good points in this little book, we may notice that the 

 rival theories of the formation of Coral Islands are very carefully 

 placed before the student (pp. 97 — 110). We doubt, however, if 

 Prof. Jukes would have so freely accepted Mr. Mun-ay's views as 

 the Editor seems to think. 



The decided value and usefulness of this " School Manual " 

 authorize us to offer the foregoing remarks on some shortcomings 

 for the Editor's consideration, — being assured that the book is well 

 suited to teacher and student in advancing the progress of liberal 

 education, and therefore worthy of all the improvements that its 

 limits will allow. Believing that the success which it has already 

 enjoyed will continue and increase, as it well deserves, we cordially 

 recommend this book to school-masters and their classes, as well as 

 to students and amateurs.
