tlo&or at the latter. On his return to Holland, he 
fettled in the praftice of his profeflion in his native city, 
where he acquired a high reputation ; and was induced 
to accept the invitation of Ifabella, princefs of the Low 
Countries, to the vacant profeflbrthip of the Inftitutes of 
Medicine at Louvain, of which he took pofleflion in 
1633. At the tame time he abjured the Proteftant faith, 
became a Catholic, and took a new degree of doftor, in 
conformity with the rules of the univerfity. In the fol¬ 
lowing year, however, he quitted this chair, for the pro- 
fetl'orthip of pathology. He was foon afterwards nomi¬ 
nated principal of the college of Breugel. He died at 
Louvain in December 1671, aged feventy. 
Plempius increafed the reputation of Louvain by the 
extent of his attainments, and was an able controver- 
fialiit, diftinguifliing himfelf in all the public queftions 
that came under difcuflion. He left the following works. 
1. A Treatife on the Mufcles, in Dutch. 2. Ophthal- 
mographia, five de Oculi Fabrica, Aftione, et Ufu, Amft. 
3632; Lovaen. 1648. 3. A tranflation of the Anatomy 
of Cabrolius into Dutch, with notes; Amft. 1633. 4. 
Fundamenta, feu Inftitutiones Medicinae; Lov. 1638, 
1644, &c. In the firft edition of this work, Plempius 
doubted the circulation of the blood ; but, in the fecond, 
he was a ftrenuous advocate for that doctrine. 5. Ani- 
madverfiones in veram Praxim curandae Tertianae pro- 
pofitam a Doftore Petro Barba; ibid. 1642. 6. Antimus 
Coningius Peruviani pulveris defenfor, repulfus a Me- 
lippo Protymo ; ibid. 1655. Coningius is the aflumed 
name of Honoratus Fabri ; Protymus was that aflumed 
by Plempius in order to decry the ufe of cinchona. 7.

Togatorum Valetudine tuenda Commentarius; Brux.

author, though Mangetus and Lipenius (probably mif- 
interpreting the initial) afcribe them to Francis Plempius.
