of Veins.—§ 2. Decay, of Rocks—Production of Soils—Their 
analysis and principles of Agricultural improvement.—§ 3. Mi- 
neral Waters—Methods of ascertaining their contents by Tests 
and by Analysis. —§ 4. Voleanie Rocks—Phenomena and Pro- 
ducts of Volcanic Eruptions. 
. An. the first. divison of each course, the principles and objects 
of chemical science, and the gencral laws of chemical changes 
are explained, and the phenomena of attraction, and of light, 
heat, -and electricity developed, and illustrated by numerous ex- 
periments. 
In the second division, the undecompounded bodies are ex- 
amined, and the modes of procuring them in a pure form, and 
of ascertaining their chemical characters, exhibited upon an ex- 
tended scale.-—The lectures on the metals include a succinct 
account of mineralogy, and of the methods of analysing and as- 
Saying ores, 
Phis part of the courses will also contain a full examination 
of pharmaceutical chemistry; the chemical processes of the 
Pharmacopeeie will be particularly described, and compared with 
those adopted by the manufacturer. 
The third and fourth divisions relate to organic substances.— 
The chemical changes induced by vegetation are here inquired 
into; the principles of vegetables, the theory of fermentation, 
and the characters of its products are then examined. 
The chemical history of animals is the next object of inquiry 
— it is illustrated by an examination of their component parts, 
in health and in disease; by an inquiry into the chemistry of 
the animal functions, and into the application of chemical prin- 
ciples to the treatinent of diseases, 
The courses conciude with an account of the structure of the 
earth, of the changes which it is undergoing, of the objects and 
uses of geology, aud of the principles of agricultural chemistry. 
The applications of chemistry to the arts and manufactures, 
and to ceconomical purposes, are discussed at some length in 
various parts of the courses; and the most important of them 
are experimentally exhibited. 
The Admission Fee to each Course is Four Guineas; or by 
paying Eight Guineas, gentlemen are entitled to attend for an 
unlimited time. 
Further particulars may be obtained by applying to Mr. Brande 
or to Mr. Fincher at the Royal Institution, 21, Albemarle-Street.
