Piso, "Willem. The Dutch, having conquered in 1630 from the Spanish 

 the north-eastern part of the Brazilian coast, between Natal and Porto Calvo, 

 Count Johann Moriz von Nassau- Sieg en was appointed, in 163G, Governor- 

 General of these possessions. He left them in 1644; the history of his reign 

 is contained in the work of Barlwus, Eerum per Octoennium . . . gestarum 

 . . . historia, Amstelodami, 1647. The Count had also instituted a scientific 

 exploration of the environs of Pernambuco (or Recife), his residence, by his 

 physician Fiso and Marcgraf, the friend of the latter (see M.), who lived also 

 at the Count*s conrt. They devoted several years (from 1638 to^ 1641) 

 zealously to their task. The results of their investigations are found in~-(l) 

 Historia naturalis Brasilise, published by Joh. de Laet, Lugd. Bat., 1643. (2)

Platearius, Matthse.us, one of the most distinguished writers of the 

 famous medical school of Salerno, about the middle of the 12th century. ^ He 

 compiled the remarkable dictionary of drugs, "Liber de simplici medicina, 

 which was extremely appreciated during the next centuries, and even reprmted 

 as late as the beginning of the 17th century. The work begins with a defini- 

 tion of the signification of the term Simplex medicina; it is in these words: 

 Circa instans negotium de simplicibus medicinis nostrum versatur propositum. 

 Simplex autem medicina est, quae talis est, qualis a natura producitur: ut 



gariofilus, nux muscata et similia The work of Platearius is therefore 



usually quoted under the name Circa instans. The list of the 273 drugs 

 enumerated in ''Circa instans" will be found in Choulant {I.e. at p. 751), p. 298. 

 We have referred to " Circa instans" as contained in the volumes — Dispen- 

 sarium magistri Mcolai praspositi ad aromatarios, Lugduni, 1517, or Practica 

 Jo. Serapionis, Lugd. 1525.
