A sword fish or Xiphias or Gladius intangled in the Herring netts at yarmouth agreable unto the Icon in Johnstonus with a smooth sword not vnlike the Gladius of Rondeletius about a yard & half long, no teeth [n _crossed out_] eyes very remarkable enclosed in an hard cartilaginous couercle about ye bignesse of a good apple. ye vitreous humor plentifull the crystalline larger then a nutmegge [cleare _crossed out_] remaining cleare sweet & vntainted when the rest of the eye was vnder a deepe corruption wch wee kept clear & limpid many moneths vntill an hard frost split it & manifested the foliations thereof. It is not vnusuall to take seuerall sorts of canis or doggefishes[56] great and small wch pursue the shoale of herrings and other fish butt this yeare 1662 one was taken intangled in the Herring netts about 9 foot in length, answering the last figure of Johnstonus lib 7 vnder the name of _canis carcherias alter_ & was by the teeth & 5 gills one kind of shark particularly [_Fol. 25_] remarkable in the vastnesse of the optick nerves & 3 conicall hard pillars wch supported the extraordinarie elevated nose wch wee haue reserued with the scull the seamen calld this kind a scrape. [56] Various species of Dog-fish are frequent off the Norfolk coast as elsewhere. The name "Sweet William" is applied to the larger fish of this kind, especially to the Tope; this appears also to have been the case in Pennant's time, for alluding to this vernacular name he supposes it was applied in ironical allusion to the offensive smell of their flesh and skin. They are objects of great aversion among the fishermen, owing to the disturbance they create among the shoals of fish, and the damage they do to both nets and the enclosed fish. Scarcely a season passes but one or more specimens of Browne's _Canis carcharias_, or, as modern Ichthyologists call it, _Lamna cornubica_, the Porbeagle, being entangled in the drift nets and landed with the herrings. One lies on the fish-wharf at Lowestoft as I write this note on the 19th of October, 1900, measuring 7 feet 10 inches in length. Jonston's figure referred to by Browne is evidently intended for this species, but he makes a slight error in the reference to the _Historia Naturalis (De Piscibus et Cetis)_; it occurs in book v., and the figure is fig. 6 on Tab. vi., and it is marked _Canis carcharias alius_ (not alter). Sturio or Sturgeon[57] so co[=m]on on the other side of the sea about the mouth of the elbe come seldome into our creekes though some haue been taken at yarmouth & more in the great [owse _crossed out_] Owse by Lynne butt their heads not so sharpe as represented in the Icons of Rondeletius & Johnstonus.
