![proneness to gullibility—the characteristics, according to some Scientists, of all who differ from themselves. What is the teaching of these four famous Physiologists ? As the object of this Society is to diffuse, as well as to acquire and accumulate, knowledge in relation to the Life, Mind, and Soul of Man, I will endeavour briefly to describe in popular language what they have discovered and asserted about the Duality of the Mind. The brain (cerebrum) is composed of a mass of twisted folds (convolutions) closely gathered together within the skull and covered with a thick membrane, fastened to the skull at a central line from front to back. This mem- brane descends into the middle of the brain, dividing it into two equal parts, or hemispheres, as they have been im- properly termed, and stretching down between the hemis- pheres to a band composed of au ashy white material (the corpus callosum), which links together the two sides of the brain—or, to speak more correctly, the two brains. Other small fibrous bands also extend from brain to brain. The brain is constructed of a mass of extremely minute fibres. These fibres extend to the extremity of the hemi- sphere to which they belong, but do not pass beyond it into the other hemisphere ; thus affording further proof that each hemisphere is in itself a complete organ. The membrane that divides the two hemispheres of the brain is called the Falx, because it resembles a sickle in shape, the point being towards the forehead. At the other end it meets a like membrane, running across the skull at right angles to it (the Gentorium). The use of these mem- branes is supposed to be to sustain the weight of thes over- lying mass when the head is reclined, so as to prevent pressure on the parts of the brain that lie beneathjfchem. From the base of each of these two brains a set of nerves descends. But these two sets of nerves do not pass into the side of the body to which the brain from which they spring [76]](https://iiif.wellcomecollection.org/image/b2244385x_0008.jp2/full/800%2C/0/default.jpg)
