    The analyses of Lassaigne were made upon the brain of a lunatic ; Analysis I by Bibra upon a sane brain (the convolutions of the cere¬ brum), II upon that of a cretin. The following by I/Heritier are those of the brain and spinal marrow of men of different ages, but without reference to any definite anatomical parts. In 100 parts. Brain. Spinal cord. Child. Youth. Adult. Old man. Cretin. Adult.

In recent years the comprehensive investigations of Bibra and Schlossberger as to the quantities of water, fat, and other solid matters in the different anatomical regions of the brain, have led to some important results. Yon Bibra did not confine his observations to the brain of man at different periods of life, but also extended them to many of the lowTer animals. We shall give here some of those analyses which have reference to the human brain, and shall state the results of the analyses of the nervous system of the other classes only in so far as is required to explain the deductions to be drawn from them.
