Tlie fifth edition of this celebrated work, valuable as an encyclopi'dia of all that was known of science at the end of 

 the XVth. Century, and regarded as the earliest work containing anatomical illustrations. 



This edition contains an ' Appedix Mnthescos ' (pp. 12S), which includes treatises on the astrolabe, perspective, etc. etc. 

 The last four 11. '.Speculum Orbis Declaratio speculi orbis compositi a Gualtero Lud. Canonico Deodatensi ' have the- 

 .-ignatures A| 4. Many of the woodcuts give illustrations of contemporary astronomical, mathematical, and chemical 

 instrumt^iits. 



'If the number were sutticient of those who wisli to take their notions of liberal education in Europe at the lime 

 immediately preceding the Reformation from original sources, and not from the reports of others, a reprint of the 

 Mi'rgarita l'hilM<i>i>hica would be made. The diversity of the matters which it treats, and the largeru'ss of its circulation, 

 stamp it as the best book for such a purpose. . . . The Arithmetic has a frontispiece representing Boethius at one table 

 with Arabic numerals before him ; and Pythagoras at another with counters, Pythagoras among the Greeks, Apulcius 

 and Boethius among the Romans, were often made the inventors of arithmetic. The arithmetic is divided into speculative 

 and practical. The former is a summary of Boethius, often in the words of John ile Muris. Tlie latter is a short treatise on 

 Algorithm, as it was called, or the rules of computation by the Arabic numerals. There is also computation by counters,. 

 fractions, common and sexagesimal, and the rule of three. Many works of fifty years later do no more diftlcult questions,' 

 etc. etc., etc. — Prof, de Morgan, who gives an interesting account of the work in his ArUhmeticnl i:oolcs,-pp. A-'.k
