' Intended to contain all the important work done in chemistry, which long remained by far the best guide to the 

 study of the science. . . He studied the processes involved in calcination, and to him is due the valuable experimental

 alchemical and other writings.' Dr. Dobbin.

'The teaching of early medieval mathematics was mainly founded on the geometry and arithmetic of Boethius. His 

 (l&ometry consists of the enunciations (only) of the first book of Euclid, and of a few selected propositions in the third and 

 fourth books, but with numerous practical applications to finding areas, etc. He acids an appendix with proofs of the first 

 three propositions to shew that the enunciations may ba relied on. His Arithmetic is founded on that of Nicomachus. A 

 textbook on music by him was in use at Oxford within the present [XlXth] century.' IP. W. R. Ball.

'Noteworthy as among, if not absolutely, the first in which the theories of the winds, as propounded by Aristotle and 

 partly adopted by Bacon, are compared with details of the trade winds, monsoons, typhoons, and winds from other parts 

 of the world, of which the classical authors know nothing. The preface shows that the author might almost rank as a 

 Maury nearly two centuries before the great American promoted the Brussels Conference. I think that the reprint of the 

 first paragraph of the preface is desirable.' G. J. Syinons, F.R.S.
