On Fibrine of Human Blood. By Dr. BucHannan. 
The author presented to the Section the fibrine of human blood, 
separated from serum, and perfectly free’d from every particle of the 
colouring matter; he detailed his mode of preparing this constituent, 
which was by carefully introducing a given quantity of recently drawn 
blood into separated serum placed on a filter: the red particles rapidly 
fall to the bottom of the fluid, and the fibrine of the introduced blood 
is free’d from its portion of serum by the filtration of this fluid through 
the coloured particles, or through sand spread on the bottom of the 
filter.

On the Therapeutic Effect of Croton Oil in certain Nervous Disorders. 
By Dr. Patrick Newsicain, of Edinburgh. 
In this paper Dr. Newbiggin demonstrated that, independent of its 
well-known purgative properties, Croton oil possessed specific influence 
in epilepsy, and in the various forms of neuralgia, as in tic-doloureux, 
sciatica, &c. Dr. Newbiggin was induced to form this opinion in
