2. Some Observations on the Coagulation of the Blood

Extract

Dr Richardson, in a recent and elaborate work on the blood, an extension of a Prize Essay on the cause of the coagulation of this fluid, has endeavoured to prove that this phenomenon is of a chemical kind, depending on the escape of the volatile alkali.

The author of the paper of the above title describes three sets of experiments which he has instituted for the purpose of testing Dr Richardson's hypothesis. In all his trials on blood, he has used that of the common fowl, its properties being best adapted to the objects in view.
