《尚书》中说：“三次折断手臂的人可以成为良医。”《楚辞》中说：“九次折断手臂的人可以成为医生。”《礼记·曲礼》中说：“如果医生的医术不是传承三代，就不服用他的药。”那么从事医学行业的人，贵在专精且持久。我的曾伯祖韵伯公，原本是生员（秀才），精研医学理论，撰写了大量的笺注、疏证和辩论文章，自己著有《来苏集》等数种书籍，但过去未曾刊印发行。我的表舅祖陈时行，是韵伯公的嫡系传人，也是受教于我伯父的人，家学渊源确实清晰无误。我家藏书颇为完备，有刻本、抄本若干卷，我们相互分析疑难、辨析诘难，力求穷尽其中的深奥道理。又与琴川（常熟）的杨资生先生讨论多年，凡是那些学识渊博且能融会贯通的儒生，都广泛地借助他们进行考证。这样看来，我伯父在医学上，既秉承了先祖的传统，又参究了明师的教导，广泛寻访了良友，冥思苦想地搜求前代哲人的智慧，可以说是既专精又持久。如今《来苏集》等书，已经刊刻并流行于世。这本书是绮石先生所著，也是我家的抄本之一，我不敢私自藏匿，于是将其雕版印刷以公之于众，既是为了阐明古人的奥秘，也是为了表明自己从中获益良多罢了。
乾隆三十六年岁次辛卯年农历十月十五日，侄男有田恭敬作跋。
上述《理虚元鉴》两卷的抄本，由无锡顾信成收藏。顾信成研究医学理论，极力称赞这本书，认为在治疗虚劳病方面，功效不亚于各家各派的著作，但在各处书坊间，散落在残破旧纸堆中的此书，很难得到。《四库全书总目提要》以及张氏的《书目答问》、朱氏的《汇刻书目》，都没有收录它。于是急忙交付刻工雕刻，流传久远，作为治疗虚劳病的专书，未必没有补益之处。由于传抄时间已久，讹误和错别字滋生很多，加上我学识浅陋，校勘并非易事。不敢随意揣测，只保留可信的内容，阙疑可疑的部分，梳理考订的工作，有待于真正喜爱此书的笃行之人。绮石先生的姓名、籍贯和居住地，急切之间难以考证。看赵氏的跋语，他难道是明朝末年的遗老或者是避世隐居的君子吗？书稿完成之际，记录于此简册之上。
大清光绪二十二年腊月，萧山陈光淞识。
The *Book of Documents* states: "One who has fractured their arm three times becomes a good physician." The *Chu Ci* (Songs of Chu) states: "One who has fractured their arm nine times becomes a physician." The *Book of Rites* (*Qu Li*) states: "If a physician's art is not transmitted through three generations, one should not take their medicine." Thus, for those engaged in the medical profession, specialization and longevity are paramount. My great-uncle, Mr. Yunbo, was originally a *Shengyuan* (a scholar who passed the county examination), who meticulously studied medical principles and produced numerous annotations, exegeses, and debates. He authored several books, including the *Laisu Ji* (Collection of Laisu), which had not been printed until now. My maternal uncle, Chen Shixing, was a direct descendant of Mr. Yunbo and received instruction from my father; thus, our family's scholarly lineage is indeed clear and accurate. Our family possessed a considerable collection of books, comprising various printed and manuscript volumes. We analyzed doubts and debated difficulties together, striving to exhaust the profound mysteries within. Furthermore, we discussed matters for many years with Mr. Yang Zisheng of Qin Chuan (Changshu). For any Confucian scholars who were both erudite and comprehensive in their understanding, we extensively relied on them for textual research. In this way, my father's expertise in medicine originated from his ancestors, was refined under enlightened masters, widely consulted among good friends, and deeply explored through the wisdom of past sages. He can be described as both specialized and enduring. Today, the *Laisu Ji* and other books have been printed and circulated. This book, authored by Mr. Qishi, is also one of our manuscript copies. I dare not keep it to myself, so I have had it engraved and published for the public, both to elucidate the secrets of the ancients and to demonstrate the benefits I have derived from it.
On the fifteenth day of the tenth lunar month of the Xinmao year, the thirty-sixth year of the Qianlong reign, my nephew You Tian respectfully wrote this postscript.
The above two-volume manuscript of *Lixu Yuanjian* was collected by Gu Xincheng of Wuxi. Mr. Xincheng studied medical principles and highly praised this book, believing that its efficacy in treating *Xu Lao* (Consumptive Disease) rivals that of various schools and texts. However, in bookshops across the regions, it is rarely found amidst fragmented old papers. It was not included in the *Siku Quanshu Zongmu Tiyao* (Summary of the Complete Library of Four Treasuries), nor in Zhang's *Mulu Dawen* (Guide to Bibliography) or Zhu's *Huike Shumu* (Catalog of Collected Editions). Therefore, I hastened to commission its printing to ensure its long-term transmission. As a specialized text for treating consumptive disease, it may well provide some benefit. Due to prolonged copying, errors and corruptions have multiplied. Given my limited knowledge, collation is not easy. I dare not speculate arbitrarily; I retain only what is credible and leave doubtful parts blank. Sorting out and verifying these matters awaits those with sincere dedication. The name, hometown, and residence of Mr. Qishi are difficult to ascertain urgently. Judging from Mr. Zhao's postscript, could he have been a loyalist of the late Ming Dynasty or a recluse who avoided the world? Having completed the writing, I record this on bamboo slips.
Recorded by Chen Guangsong of Xiaoshan in the twelfth lunar month of the twenty-second year of the Guangxu reign, Qing Dynasty.
