    This engraving was taken from the same head as plate XLI. A The os frontis. B The os nasi. C The cartilaginous and membranous part of the nose. D The ala nasi, with the skin left on. E The septum narium. F The upper lip. G The cut surface. H H H The alveolar process of the superior maxillary bone. I Part of the antrum. K The os occipitis. L The body of the sphenoid bone. M The groove made by the carotid artery. N The posterior clinoid process. O the sphenoid sinus. P The crista galli. Q The membrane of the nose. R The membrane, a little more convex, where the inferior turbinated bone is situated. S The same where the superior turbinated bone is situated. T The branch of the fifth pair of nerves that was supposed to be lost on the membrane of the nose. U U U The trunk of the first pair of nerves which is afterwards lost upon that part of Schneider’s membrane that covers the turbinated bones. PLATE XLIII. Fig. 1. A transverse section of the crystalline humour of the eye of a cuttle-fish, to show its structure; the central part is transparent, but the others are opaque, having been coagulated by proof spi- rits ; and for the appearance of distinct fibres surrounding the central part. These fibres are not uniform circles or ovals, since the layers are of different thicknesses in particular parts, a a. The fibres where they are most numerous, b b. Where they are least so. Fig. 2. A section of the crystalline humour, the central part being removed, to show the fibrous struc- ture of the surrounding laminae. PLATE XLIV. This fish is called a Grampus a; it was caught at the mouth of the river Thames, in the year 1759, and brought up to Westminster Bridge in a barge. It was twenty-four feet long. PLATE XLV. Another species of Grampusb, which was caught in the river Thames, fifteen years ago. It was eighteen feet long. PLATE XLYI. Fig. 1. A species of Bottle-nosed Whale; the Delphinus Delphis of Linnaeusc. It was caught upon the sea-coast, near Berkeley, where it had been seen for several days, following its mother, and was taken along with the old one, and sent up to me whole, for examination, by Mr. Jenner, Surgeon, at Berkeley. The old one was eleven feet long. Fig. 2. The head of the same Whale as fig. 1. to show the shape of the blow-hole, which is transverse, and almost semicircular. a [Phocana Orca, Cuv. Delphinus Orca, Linn. This is acknowledged to be the most accurate figure of the Grampus hitherto published; and is cited by M. Fred. Cuvier as the type of that species. See Histoire des Cetaces, 8vo. 1836, p 177.] h I have searched in vain among the existing documents, relating to Mr. Hunter’s researches on the Cetacea, for any note or memorandum tending to authenticate the above description. The original drawing, coloured after nature, exists in the Hunterian Collection, and is marked 1 Porpus’. It is unnecessary to observe to those who have examined the common Por- poise, (Plioccena communis, Cuv.) that the figure in Plate XLV. is an exact representation of that species. c [This is the Delphinus Tursio of Fabricius, the ‘ Grand Dauphin ’ or Souffleur of Cuvier; and a larger species than the Delph. Delphis, Linn., but with fewer teeth, having from 21 to 23 obtuse conical teeth on each side of each jaw, while the Delph. Delphis has double that number.]
