III.—An Inexpensive Apparatus for the Isolation of Minerals By Means of Heavy Liquids.3
Published online by Cambridge University Press: 01 May 2009
Extract
I am aware that in describing a new apparatus for separation by heavy liquids, I am adding another item to a list which is already a very long one. My only excuse is that this particular form has the advantage of being easily and cheaply constructed from ordinary chemical apparatus, and yet has most of the advantages of Thoulet's comparatively expensive form.

A short notice of my apparatus in its simplest form will be found at p. 108 of the interesting and valuable Manual by Professor Cole, of the Royal College of Science, Dublin, entitled, “Aids to Practical Geology,” which has just been published.

page 69 note 1 I have not arranged for the calculation of density from the volumes used. If required, the apparatus could be graduated (being heightened if necessary). Practically it is better to dilute with a solution only slightly lighter till separation takes place and then determine the density by one of the usual methods.
