friends from foes, those in favour from those who are opposed, given the part played by that raffish and disreputable trouble-maker Buck Jones in this whole business about the chair.
Now then, you Portuguese, calm down and listen patiently. As you know, the skull consists of the bones enclosing the brain, which in its turn, as we can see from this anatomical chart in natural colours, is nothing less than the upper part of the spinal cord. Compressed all the way down the back, it found a space there and opened out like a flower of intelligence. Note that the comparison is neither gratuitous nor disparaging. There is an enormous variety of flowers, and we need only remember, or let each of us remember the one we like best, and in the last resort, for example, the one we dislike most, a carnivorous flower, de gustibus et coloribus non est disputandum , assuming we share this horror of anything that denatures itself, although in keeping with that basic rigour demanded of those who teach and learn, we ought to question the justice of this accusation, and although, once more so that nothing is overlooked, we should ask ourselves what right a plant has got to nourish itself twice, first on the soil and then on whatever is flying through the air in the multiple form of insects, or even birds. Let us note in passing how easy it is to suspend judgement, to receive information from all sides, accept them at face value, and remain neutral on the grounds that we are an undivided spirit, and offer daily sacrifice at the altar of prudence, our best fornication. We were not neutral, however, as we watched that fall in slow motion. And a degree of prudence has to be sacrificed if we are to accompany, with due attention, the movement of the pointer passing over this incision in the brain.
Observe, ladies and gentlemen, this longitudinal bridge, as it were, made from fibres: it is called the fornix and constitutes the upper part of the optic thalamus. Behind can be seen two transversal commissures which obviously are not to be confused with those of the lips. Now let us examine the other side. Look here. What you see standing out are the quadrigeminal tubercles or optic lobes (and since this is not a Zoology lesson, the accent on lobes is heavily stressed on the o). This broad section is the anterior brain, and here we have the famous convolutions. Right underneath, as everyone knows, is the cerebellum which contains what is known as the arbor vitae, and in case anyone mistakes this for a Botany lesson, we should explain that this is due to the plicae of nervous tissue in a certain number of lamellae, which in their turn produce secondary folds. We mentioned the spinal cord earlier. Take a good look at this. It is not a bridge yet is known as the bridge of Varolio, which sounds more like the name of an Italian town, and I defy you to disagree. Behind is the elongated medulla. I have almost finished this description, so bear with me. Much more could be explained and in greater detail, but only if we were carrying out an autopsy. Therefore let us simply point out the pituitary gland, a glandular and nervous organ at the base of the thalamus or third ventricle. And to conclude, let me point out the optic nerve, a subject of the greatest importance, and now no one can claim not to have witnessed what happened in this place.
And now to the crucial question: what purpose does the brain, or brains as they are commonly known, serve? They serve for everything because they allow us to think. But we must be careful not to be deceived by the common misconception that everything inside the skull is related to thought and the senses. An unforgivable error, ladies and gentlemen. The greater part of this mass inside the cranium has nothing to do with thought and does not influence it in any way. Only the thinnest layer of nervous tissue, known as the cortex, about three millimetres thick, and covering the anterior part of the brain, constitutes the seat of
