Fig. 1. The Head of a Whiting opened.
- The upper Region of the Brain of a Whiting is formed of six Processes of dif∣ferent shapes and sizes.
- † a a. THe first pair of Protuberancies †, being the smallest of all, is adorned with an Orbicular figure.
- † b b. The second pair † being above double in magnitude, are beautified with an oblong Oval shape.
- † c c. The third pair of Processes † are adorned with an inverted Pyramidal figure, as their Bases are above and the Cones below; and do constitute the Cerebellum, divided in the middle by a Fissure.
- † d d. † e e. Below may be seen the Medulla Spinalis † out of whose beginning on each side of it, doth arise a Nerve †, which olimbing up, doth encircle the Processes of the Cerebellum and Brain, and afterward intersect the Optick Nerves, and passing all along the Head, do intersect each other, and at last terminate into Arches.
- † f f. The Optick Nerves † do creep out of the Brain under the Orbicular Processes, and pass obliquely into the inside of the Eyes.
- † g g. † h h. The Olfactory Nerves † creep out of the Brain under the Orbicular Processes, and do associate for some space, and afterward part and are at last implanted with va∣rious Fibrils into the Organs of Smelling †.
Fig. 2. The lower Region of the Brain of a Whiting, consisteth of a row of five Processes, and the most minute is seated in the middle † dressed with a Globular figure.
- † a. † b b. The inward adjacent Processes † are trimmed with an Oval shape.
- c c. The outward Protuberancies seem to be pointed †, beginning in acute and ending in obtuse Cones.
Fig. 3. The Head of a Pearch opened.
- The upper Region of the Brain of a Pearch is made up of two pair of Processes, and of a single Protuberance.
- † a a. The first pair † are the smallest, and decked with an Orbicular figure.
- † b b. The second pair † are adorned with an Oval figure.
- † c. The last is a single Process †, beautified with a kind of Triangular figure.
- † d. The Medulla Spinalis † is parted in the middle (as in other Fish) into two equal parts.
Fig. 4. The lower Region of the Brain of a Pearch is endued with four Processes seated in a rank.
- † a a. † b b. The two middle Prominencies † are dressed with an Oval figure, and the two lateral (as they are placed by Nature) seem to enclose the middle Processes after the man∣ner of Semicircles.
Fig. 5. The Head of a Gudgeon opened.
- † a. † b. The Brain of a Gudgeon is composed of three pair of Processes: The first † are en∣dued with a minute Orbicular figure; And the second pair † are somewhat larger, and are beautified also with the same figure.
- The third are the largest, adorned with an Oval shape.
- † c c. † d. The two last are single † Processes †, placed one below another, the one great and the other small, and both Orbicular, and make the Cerebellum.
- † f f. The Medulla Spinalis † is disposed into equal parts by the mediation of a Fissure run∣ning in the middle.
- † e e. The Olfactory Nerves † arising under the minute pair of Globular Processes, make their progress toward the Mouth.
Fig. 6. The Head of an Eel opened.
- The Brain of an Eel consisteth of two ranks of Processes, and a single Protuberance.
- † a. The first rank † hath three in number, dressed with a Globular figure.
- † b b. The second rank † hath two decked with an Oval.
- † c The posterior Process † seemeth to be adorned with a quadrangular figure.
- † d d. The Medulla Spinalis † is little different from that of other Fish, as consisting of two parts, equally divided in the midst by a Fissure.
- † e e. The Optick Nerves † seem to be derived from each side of the lateral Orbicular Pro∣cesses, seated in the first rank, and pass in an oblique transverse posture, and are inserted at last into the inside of the Eyes.
