to be equal, it is evident that we must first compute 

 the value of 360 yards at 3s. 6d. per yard, and then 

 find how many yaiJs, at 17s. 6d. per yard, can be 

 purchased for the amount.

The above question might also have been solved 

 by one stating, thus :

Hence it may be inferred, in general, that if the 

 quantity of one commodity be multiplied by its rate, 

 the product, divided by the rate of the other com- 

 modity, will give its quantity.

BARTHELEMY, Jean Jaques, a French Abbe, 

 eminently distinguished by his literary attainments and 

 virtues. He was born in Jan. 1716 at Cassis, a small 

 seaport in Provence. Being destined for the church, 

 he was sent at twelve years of age to study at Mar- 

 seilles, where he was admitted into the college of 

 the oratory, under the tuition of father Renaud, a 

 man of learning and taste, who became warmly at-

tached to his young pupil. It became necessary for Bartkele- 

 him, however, to quit this seminary, *n account of m y - 

 an ordinance of the bishop of Marseilles, by which 

 students of the oratory were refused admission to holy 

 orders. With much regret, therefore, Barthelemy 

 was obliged to quit his esteemed preceptors, and to 

 betake himself to the study of philosophy and theolo- 

 gy under the Jesuits. 



Dissatisfied, however, with the plan adopted by his 

 new masters, he determined to follow a method of his 

 own, in private ; and applied to the study of the an- 

 cient languages, as well as of the Hebrew, Chaldean, 

 and Syriac, with such indefatigable perseverance, that 

 it had nearly cost him his life. Having recovered 

 from a dangerous illness, brought on by too intense 

 an application to study, he at length entered the se- 

 minary, where he received the clerical tonsure. Here 

 he made such progress in the study of Arabic, by the 

 assistance of a young Maronite, who had been edu- 

 cated at Rome, that he was able to deliver some ser- 

 mons in that language, composed by a Jesuit belong- 

 ing to the Propaganda, to an assembly of Maronites, 

 Armenians, and other Catholic Arabians, then at 

 Marseilles. He also gave another uncommon specimen 

 of his proficiency in the oriental languages ; for, at 

 the age of twenty-one, at the request of some of the 

 principal merchants of Marseilles, he, with great ap- 

 plause, conducted a learned dialogue, with an itinerant 

 Jewish rabbin, who had become a professor of the 

 Christian religion, and claimed to be deeply skilled in 

 the languages of the East. 



Having finished his studies at Marseilles, Barthe- 

 lemy retired to his family at Aubagne ; but was ac- 

 customed to repair occasionally to his former resi- 

 dence, in order to enjoy the society of the academi- 

 cians, and other learned men residing there. Among 

 those to whom he more particularly attached himself, 

 was a M. Cary, the possessor of a valuable collection 

 of books, and fine cabinet of medals ; so that now he 

 laid the foundation for that knowledge and taste in 

 antiquities for which he was afterwards so justly ce- 

 lebrated. It was in 1744 that Barthelemy repaired 

 to Paris, with a view of devoting himself entirely to 

 literature. He was furnished with a letter of intro- 

 duction to M. de Boze, keeper of the royal cabinet 

 of medals, and perpetual secretary to the academy of 

 inscriptions and belles lettres. By this eminent anti- 

 quarian he was warmly patronised, and introduced to 

 the acquaintance of the most distinguished members 

 of the three academies, who dined twice a week at his 

 apartments. In such society the taste and knowledge 

 of Bartheiemy could not fail to be materially improved. 



In consequence of the declining health, and increa- 

 sing age of M. de Boze, an associate became necessa- 

 ry to aid him in the labour of completing the royal 

 cabinet of medals ; and Barthelemy was selected for 

 this office, in preference to M. Bastie, a learned mem- 

 ber of the academy of inscriptions. From this mo- 

 ment he devoted the whole of his attention and care 

 to the elucidation of that branch of study which had 

 now become his official employment. In 1747, he 

 succeeded M. Burette as associate to the academy of 

 inscriptions ; M. le Beau, who had been a candidate, 

 declining a competition with so eminent an antiqua- 

 rian. When he was afterwards nominated by the mi-
