    4. The cerebellum bears much the same relation to the whole en- cephalon throughout the duration of life, at least after very early- age. In the adult male it averaged 1 to 9-03, and ranged from 1 to 7-7 to 1 to 10-2. In the adult female it averaged 1 to 8-9, and ranged from 1 to 8-3 to 1 to 9-5. 5. The specific gravity of the brain in the adult is similar in the two sexes (1-036 in both the male and female); nor is there any very material difference in the density of the several portions of the encephalon; the specific gravity of the cerbeUum and of the pons Varolii and medulla oblongata being, however, in both sexes, greater than that of the cere- brum. The observations do not afford satisfactory information as to the influence of age on the specific gravity of the brain. 6. The observations in the weight and specific gravity of the diseased brain are too few to warrant any conclusions being deduced from them; but there can be no doubt, that the brains of persons who die of inflammatory diseases of that organ, or of diseases which interfere with the fr-ee transmission of the blood through the lungs and occasion gene- ral venous congestion, are usually heavier than those of persons who die of other affections.
