百科全书自然史图版页

一张20世纪初自然史参考书百科全书图版单页，全保真复制于奶油色书页纸。顶部14pt粗体大写标题：「PLATE XXIII — CEPHALOPODA」，细横线分隔。页面几乎完全由精确标注的科学插图构成：八种头足类动物——鹦鹉螺、章鱼、三种乌贼、墨鱼、纸鹦鹉螺（Argonauta）与菊石化石——均以细黑铜版雕刻线绘于奶油底。每件标本带数字编号（1–8）及正下方8pt斜体拉丁双名法：「1. Nautilus pompilius」、「2. Octopus vulgaris」等。底部页边距9pt简短说明段落。页码"347"右下角。左边距细索引标签「1. Nautilus pompilius」。插图有效利用空间——鹦鹉螺横截面最大居中，较小物种填充角落。整体风格权威、精准、略带庄严朴素。

A single encyclopedia plate page from an early 20th-century natural history reference work, reproduced at full fidelity on cream book paper. The plate is titled at the top in 14pt bold uppercase: "PLATE XXIII — CEPHALOPODA" with a thin rule below. The page is composed almost entirely of precisely labeled scientific illustrations: eight species of cephalopods — nautilus, octopus, three squid varieties, cuttlefish, paper nautilus (Argonauta), and ammonite fossil — each rendered in fine black engraving line on cream. Each specimen bears a number (1–8) and a Latin binomial in 8pt italic directly below: "1. Nautilus pompilius", "2. Octopus vulgaris", etc. A brief explanatory note paragraph in 9pt runs along the bottom margin. Page number "347" bottom-right. The left margin contains a thin index tab marker reading "MOLLUSCA". The illustrations are arranged to use space efficiently — the nautilus cross-section is largest, centered; smaller species fill corners. The overall aesthetic is authoritative, precise, and faintly austere.
