 in the greatest reverence and esteem. 

 The Mussulmen dare not touch it without 

 being first washed, or legally purified ; 

 to prevent which, an inscription is put on 

 the cover or label : " Let none touch it 

 but they who are clean." It is read with 

 great care and respect They swear by 

 it, take omens from it on all weighty oc- 

 casions, carry it with them to war, write 

 sentences of it on their banners, adorn it 

 with gold and precious stones, and do not 

 suffer it to be in the possession of any who 

 hold a different religion.

ALEMBERT (Jonx LE ROXD D') an 

 eminent French mathematician and philo- 

 sopher, and one of the brightest orna- 

 ments of the 18th century. He was per- 

 petual secretary to the French Academy 

 of Sciences, and a member of most of 

 the philosophical academies and societies 

 of Europe. 



D'Alembert was born at Paris, the 16th

 name of John le Rond, from that of the 

 church, near which, after his birth, he

 circumstance, listening to the voice of 

 nature and duty, took measures for the 

 proper education of his child, and for his 

 future subsistence in a state of ease and

 demoiselle Tencin, sister to cardinal Ten- 

 cin, archbishop of Lyons. 



He received his first education among 

 the Jansenists, in the College of the Four 

 Nations, where he gave early signs of 

 genius and capacity. Jn the first year of 

 his philosophical studies, he composed a 

 Commentary on the Epistle of St. Paul to 

 the Romans. The Jansenists considered 

 this production as an omen, that portend-

 tion to some part of their former splen-

 resemblance more complete, they enga- 

 ged their pupil in the study of the ma-
