12835 ORTA (Garcia da) COLLOQUIES on the SIMPLES and DRUGS of INDIA [1563] ; New Edition 

 (Lisbon, 1895), edited and annotated by the CONDE DE FICALHO, translated, with Introduction and 

 Index, by SIR CLEMENTS ROBERT MARKHAM, K.C.B., F.R.S., with 25 full-page illustrations from 

 the quaint engravings in ' Historia Natural y Morale de las Indias ', por Jos. de Acosta (1590), sm. 

 4to. buckram, uncut, t. e. g. (250 COPIES PRINTED, ONLY 200 OF WHICH ARE FOR SALE), 2. 2s 1913 



The celebrated ' Coloquious d'os Simples e Drogas da India ' of Garcia da Orta were first published at Goa in 1563. The 

 author went out to India in 1534 as physician to his feudal lord Dom Martin da Sousa, afterwards Governor of Goa, and 

 stayed there until his death in 1570. Travelling extensively along the western seaboard of India and in Ceylon, 

 Garcia gathered botanical and pharmaceutical knowledge at first hand wherever he went. He formed a large ' physic 

 garden ' in Goa, and another in Bombay, on the site now occupied by the Victoria Gardens. The ' Colloquies ' was in all 

 probability the first European book printed in T ndia ; it contains the first descriptions of many Indian plants now in 

 widespread medical use, and of their application to such diseases as cholera and dysentery. Clusius in his ' Aromatum 

 Historia ' made a short, unsatisfactory precis, and the Italian and the French translations are very inferior to the 

 original. Sir Clements Markham was engaged on his translation from the standard Portuguese edition, at Lisbon 

 and Madrid, for the greater part of three years. On the proposal of Sir George Birdwood the publication was under 

 the patronage of the Secretary of State for India. The work has more than a scientific interest, for it is enlivened by 

 entertaining anecdotes of the manners and customs of the people among whom Garcia da Orta carried on his researches. 



This is the first English translation of this famous book, and it will be found to appeal not only to the Botanist and 

 Pharmacist, but also to the many students of Indian subjects, as well as the lover of Belles Lettres, who will be 

 agreeably pleased by its quaint and curious style, so reminiscent of the Dialogues in Walton's 'Angler.' 



'In spite of occasional bombast or intolerance a remarkable book; and all who are concerned with the history ot 

 simples are under great obligation to Sir Clements Markham for his painstaking translation from a language which lew 

 are able to read '.Times.
