布封是18世纪法国著名的博物学家和作家。他坚持以唯物主义的思想看待地球与生物的起源和发展，被誉为“和大自然一样伟大的天才”。

　　《自然史（第3卷）》是一部博物志，书中以大量的科学观察为基础，从唯物主义的角度对自然界的各种现象做了详细的描述。书中提到的“物种可变”和“进化”的思想对当时的社会具有积极的启蒙作用，也对后来达尔文提出“物种起源”与“进化论”产生了深远影响。

　　《自然史（第3卷）》原著为法文，共44卷。本版为英国学者James Smith Barr在1797-1807年翻译出版的10卷册，是原著中*精华的部分，主要包括地球的理论、动物史、人类史、家畜驯养史，并简单介绍了矿物和植物等内容。

　　《自然史（第3卷）》可供生物学、生态学、地质学等专业的高校师生和相关科研人员以及博物爱好者阅读。

　　在已探知的星球中，唯地球有人类。人类社会和自然界构成了这颗星球的整个世界。人类来源于自然，依赖于自然，不断地探索自然，了解自己从何而来，向何而去？为什么在这万物共生的自然界脱颖而出，成为这个世界的主宰？又怎样与这个世界大家庭和睦相处，适应客观发展？……只有了解过去，才能更好地认识现在；懂得了过去和现在，才能主动地面对未来。历史是最好的教科书，在《地球简史》《人类简史》《时间简史》等纷纷面世的当代，人们不由地把目光又投向260多年前就诞生了的《自然史》，这部洋洋数百万字的旷世巨著，开辟了科学史作的先河，它从行星到地球，从空气到海洋，从动物到人类，……天、地、生、人，无所不包，海、陆、空，面面俱到，是一部记述自然的百科全书。

　　书中全面论述了地球理论和地球历史，展现了风、火、水、潮、雷、震（地震）、光、热等各种自然现象；对人和生物的论述更是生动形象，丰富多彩。从生命的起源、器官的发育、青春期的特点，到机能的退化，直至死亡，把人类生息繁衍的过程讲得有声有色。对生物，特别是动物的描绘投下了重重笔墨，占据了大量篇幅，天上飞的，地上长的，野生的，驯养的，食肉的，食草的，大到熊、马，小至鼠、兔，畜、禽，鸟、兽，花、草、树、木，样样俱全，活灵活现，既有理性，又有情趣，好像无论哪种野性的动物都可以成为人类的宠物和朋友。法国著名思想家卢梭是这样评价的：“布封以异常平静而又悠然自得的语言歌颂了自然界中所有的重要物品，呈现出造物者的尊严与灵性。他具有那个世纪最美的文笔。”

　　万物皆有道，自然最奇妙。几乎所有涉及自然的事物都可以从《自然史》汲取营养，得到启示。读这类名著，既能增长知识，丰富阅历，又能赏心悦目，闲情逸致。即使历史已过去了几百年，社会发生了巨变，也未失去这部历史巨著的价值和魅力。这就是一部不朽之作的历史地位。布封在书中提出“物种可变”和“进化”的思想，被生物进化论创始人达尔文称为“以现代科学眼光对待这个问题的第一人”。

　　哲语说，文如其人。《自然史》的作者布封，全名乔治.路易，勒克莱尔，布封（Georges-Louis Leclerc，Comtede Buffon，1707-1788），如同他的不朽著作一样，也有一部不寻常的经历。他生于法国，自幼喜好自然科学，特别是数学。1728年法律专业毕业后，又学了两年医学。20岁时就先于牛顿发现了二项式定理；26岁成为法兰西科学院机械部的助理研究员，翻译并出版了英国博物学者海尔斯的著作《植物生理与空气分析》和牛顿的《微积分术》；1739年，32岁的他转为法兰西科学院数学部的副研究员，并被任命为“巴黎皇家植物园及御书房”的总管；1753年成为法兰西科学院院士。他用40年的时间写出了长达36卷的《自然史》，后又由他的学生整理出版了8卷，共44卷。此书一出版，就轰动了欧洲的学术界，各国很快有了译本。1777年，法国政府给布封建了一座铜像，上面写着：“献给和大自然一样伟大的天才。”这是对布封的崇高评价。

　　《自然史》原著为法文，这里出版的是英国学者James Smith Barr在1797-1807年翻译的英文版10卷册，选取的是原著中最精华的部分。发行这样的英文版高级作品、高级读物，就像外文书籍、外文刊物一样，自然面对的也是高水平的读者和馆藏者，希望他们既可以接近原汁原味地欣赏原著，感受自然的魅力，受到自然科学和文学艺术的熏陶，同时又能自然而然地提高英文素养和写作水平。在广大知识分子外语水平普遍提高的今天，这样的科学传播形式也许会受到越来越多读者的青睐。

　　布封出生于法国蒙巴尔城的一个律师家庭，自幼接受教会教育，对自然科学始终有着浓厚的兴趣。1730年，大学毕业的布封结识了年轻的金斯顿公爵，两人一起游历了法国南部、瑞士和意大利，并在这位公爵的家庭教师的影响下开始研究博物学。1733年，布封进入法兰西科学院担任助理研究员，1739年，成为巴黎皇家植物园园长，1753年，当选为法兰西科学院院士。布封毕生从事博物学研究，花费40年心血著成《自然史》这部煌煌巨著。《自然史》共44卷，是一部博物志，包括了地球史、人类史、动物史和矿物史等，堪称百科全书式的巨著。书中提到的“物种可变”和“进化”的思想对当时的社会具有积极的启蒙作用，也对后来达尔文提出“物种起源”与“进化论”产生了深远影响，布封地因此被达尔文称为“以现代科学眼光对待这个问题的第1人”。

　　《自然史（第3卷）》：

　　By the experiments we have just described, I was assured that females,as well as males, have a seminalliquor which contains moving substances; that these substances were not real animals, but only living organic particles; and that those particles exist, not only in the seminal liquors of the two sexes, but even in the flesh of animals, and in the germs of vegetables. To discover whether all the parts of animals, and all the germs of vegetables, contained living organic particles, I caused infusions of the flesh of different animals to be made, and of more than twenty kinds of seeds of different plants; and after they had infused four or five days, in phials closely stopt up, I had the satisfaction to see moving organic parts in them all; some appeared sooner, and others later; some preserved their motion for months together, while others were soon deprived ofit; some directly produced large moving globules, that had the appearance of real animals, which changed their figures, separated, and became successively smaller: others produced only small globules, whose motions were very brisk; others produced filaments which lengthened and seemed to vegetate, swelled, and afterwards thousands of moving globules issued therefrom; but it is useless to detail my observations on the infusion of plants, since Mr. Needham has published so excellent a treatise on the subject. I read the preceding treatise to that able naturalist, and often reasoned with him on the subject, particularly on the probability that the germs of vegetables contained similar moving bodies to those in the seed of male and female animals. He thought those views sufficiently founded to deserve to be pursued; and therefore began to make experiments on all parts of vegetables; and I must own that the ideas I gave him on this subject have reaped greater profit under his hands than they would have done from me. I could quote many examples, but shall confine myself to one, because I indicated the circumstance I am going to relate.

　　To determine whether the moving substances seen in the infusions of flesh were true animals, or only, as I supposed, moving organic particles, Mr. Needham imagined that he had only to examine some roasted meat, because if they were animals the fire must destroy them; and if not animals, they might still be found there as well as when the meat was raw; having therefore taken the jelly of veal, and other roasted meat, he infused them for several days in water, closely corked up in phials, and upon examination he found in every one of them a great quantity of moving substances. He shewed me some of these infusions, and among the rest that of the jelly of veal, in which there were moving substances, perfectly like those in the seminal liquor of a man, a dog, and a bitch, when they have no threads, or tails; and although we perceived them to change their figures, their motions so perfectly resembled those of an animal which swims, that whoever saw them, without being acquainted with what has been already mentioned, might certainly have taken them for real animals. I shall only add, that Mr. Needham assured himself, by a multiplicity of experiments, that all parts of vegetables contain moving organic particles, which confirms what I have saidi and extends my theory on the composition of organized beings, and their reproduction.

　　All animals, both male and female, and all vegetables whatsoever, it is therefore evident are composed of living organic parts. These organic parts are in the greatest abundance in the seminal liquor of animals, and in seeds of vegetables. It is from the union of these organic parts returned from all parts of the animal or vegetable body, that reproduction is performed, and is always like the animal or vegetable in which it operates; because the union of these organic parts cannot be made but by the means of an internal mould, in which the form of an animal or vegetable is produced. It is in this also the essence of the unity and continuity of the species consists, and will so continue while the great Creator permits their existence.
