Those who wish to repeat successfully the experiments referred 
to above, must make use of several pints, at least, of blood and of

A paper containing the results of a lengthened inquiry as to the 
accumulation of fluorine will appear in the coming volume of the 
Transactions of the Royal Society of Edinburgh.
