The old German in Fraktur font, as well as near literal translation, is challenging.
BUT a loose translation of the text is as follows:
From the inhabitant of the nerites.

Dissecting from the resident
Herr Adanfon, being in Senegal, was able to get to know these snails and their inhabitants very well, because there such an enormous crowd, especially on the resourceful part of the island, from the village of Rufisk to Ben, could be found if they high sea there drives to the shore in April, so that one saw it as it were completely covered by it. I am, therefore, quite able to acquaint the enthusiasts with it, following Mr. Adanson's instructions.

fi. 1.
a. The inhabitant has an extraordinarily large crescent-shaped head (28th Vign. ​​1. fig. lit. a.), which is half as broad as the shell itself, flat on top, but arched below, and cutting at the edges.
fig. 1. bb.
The antennae resemble, according to their shape, two triangular ones Tongues flattened at their sides, thrice as long as broad, but thrice times shorter than the head on which they are at the top, quite far from a and stand almost at the edge of the two sides.
-lit. cc
the eyes c. c. is seen almost entirely in the middle of the whole length of the head, on the outer side of the antennae, but just as far behind them as the antennae are broad. They are of medium height, black in colour, round and somewhat raised in figure.

C. The mouth (Fig. 2. fig. d.) is easily recognized by a long tube (Ibid. lit. e), which the animal often protrudes. This cylindrical tube has the same length as the head. It is open in front, and armed with a few hooked teeth. The occupant uses the same to pierce other shells and to feed on their occupants by sucking out their sticky sap.

lit. f. f.
The cloak wraps itself around the walls of the shells without becoming visible. At the anterior end it curves into a strong canal (Fig. 1. and 2. lit. f. f.), as long as the head together, on which it is accustomed to lie between the antennae. It is cylindrical, very thick, cut off along its entire length in front. On either side of this canal one discovers a thick, fleshy, square shape Fig. 2. g.g.), which encloses the whole length of it. In the second figure, this strong tube has been shown as it appears on the left-hand side of…

Conchology (from Ancient Greek: κόγχος konkhos, "cockle") is the study of mollusc shells. Conchology is one aspect of malacology, the study of molluscs; however, malacology is the study of molluscs as whole organisms, whereas conchology is confined to the study of their shells.
Friedrich Wilhelm Martini (1729–1779) was a German physician and natural scientist.

| The Nature of Prints & Engravings: It was not until the 20th century that prints were commonly produced for the print itself. Prior to this, virtually all prints (and engravings) were produced as illustrations to be included in a manuscript, book, newspaper, or pamphlet. Therefore, a vast majority of original prints have been over the years removed from these original sources. Prints are produced using many different techniques: relief printing (woodcut & wood engraving), intaglio printing (steel & copper plate engraving, drypoint, aquatint, etc), and planographic printing (lithography, serigraphy, inkjet, laser, etc.). While the commercial value of a print depends on such factors as age, rarity, and condition, the real value of a print is its tie to its history and/or its esthetic beauty. |
