2. To what source are we to ascribe the iron which we find 
in the analysis of some plants? Is it to be ascribed in every case 
to particles of iron which the plants have taken up with their 
natural aliment, or can it be evidently proved by observations, 
that it is produced at least in some cases by the vegetation itself? 
And what light do these observations throw upon other branches 
of physics ? 
ROYAL INSTITUTION.

In 1704, Sir Patrick Dunn instituted, in his life-time, two 
Professorships in Dublin, viz. * one of Osteology, Bandages, and 
Operations of Surgery, and one of ancient and modern Materia 
Medica, and Pharmacy.” Sir P, Dunn further directed by his 
will in 1711, that, if his funds were sufficient, “‘ there should be 
Lectures publicly read on the Anatomy of the Bodies of Men, or 
the Bodies of Animals—on Chirurgery and Midwifery—on Bo- 
tany and the Dissections of Plants.” He also ordered, that the 
Professorships on these several subjects should be bestowed ac- 
cording to the merits of the candidates, to be ascertained by an 
examination on three several days, two hours each day. A King’s. 
Professor of the Theory and Practice of Physic, with corporate 
powers of holding and letting lands, was instituted by George 
the First. 
An act was passed in the 21st year of George the Second, by. 
which the King’s Professorship of Physic, and the Professorship 
of Surgery and Midwifery, and that of Materia Medica and. 
Pharmacy, instituted by Sir Patrick Dunn, were incorporated - 
and established by law. Before this period also, Lectureships — 
existed
