新编张仲景注解《伤寒百证歌》五卷，《发微论》二卷，题为白沙许叔微（字知可）述。《直斋书录解题》记载：许叔微的《伤寒歌》三卷，共一百篇，都依据张仲景的注释。又有治法八十一篇，张仲景脉法三十六图，《翼伤寒论》二卷，《辨类》五卷，这些都没有见到。
《四库全书总目提要》记载：许叔微字知可，是真州人。绍兴二年进士及第。医家称他为许学士，不知道他担任过什么官职。考证认为，《伤寒歌》即《百证歌》，三卷与五卷大概是文字传抄错误。《翼伤寒论》就是《发微论》。许叔微是扬州仪征人，年少时父亲去世，努力学习，对于书籍无所不读，尤其精通医学。建炎初年，大盗张遇攻破真州，不久后瘟疫大作。许叔微走遍乡里门户，诊视病人并给药，十人中能救活八九人。他做官做到徽州、杭州的教官，升迁至京秩（中央官员等级）。看到影印宋抄本中干道庚寅年张郯所作的序，以及《独醒杂志》、《西溪丛话》、张杲的《医说》等书。许叔微所著的《类证普济本事方》十卷，在《宋史·艺文志》、《书录解题》、《文献通考》、《四库全书》中都有著录。我仅在《书录解题》中见过。《脉法类辨》早已失传，《八十一法》应该就是张月霄藏书志中著录的《伤寒九十论》、《百证发微》。自元明以来，这本书不太显赫。
《四库全书》未收录，阮元（阮文达）、张月霄也都未曾见过。只有钱遵王在《读书敏求记》中著录。钱遵王收藏的元代刊本现在归我所有。医学界有张仲景，就像儒家有孔子一样。医书中有《伤寒论》，就像儒书中有“四书”一样。宋代研究这门学问的人，有成无己的注本，李柽的《要旨》，王实的《证治》，韩祗和的《微旨》，庞安常的《总病论》，朱翼中的《活人书》，钱闻礼的《百问歌》，虽然各自都有长处，但许叔微的书最能领会其意蕴。《百证歌》用七字韵语写成，意思涵盖全面而语言简练；《发微论》探究精微、搜求深奥，妙悟通达神妙。由此感叹许叔微学问之深厚且深远，不是那些技艺浅薄、偏执一端的人所能企及的。明代万历辛亥年有乔山堂的坊刻本，合为四卷。对照元刊本，不仅面目全非，窜改之处也不少。这是明代人刊刻书籍的通病，在医书中尤为严重。我担心它误导庸医从而害人性命，所以重新摹刻元刊本以广泛流传。后世研究医家言论的人，通过此书来探求张仲景的学说，或许可以避免被讥笑为荒废医术吧。
光绪七年，岁次重光大荒落（丁丑年），季冬之月既生霸（农历十六日），归安陆心源撰写。
Newly compiled Zhang Zhongjing's annotated *Shanghan Baizheng Ge* (Song on Hundred Syndromes of Cold Damage), five volumes; *Fawei Lun* (Discourse on Unveiling the Profound), two volumes. Attributed to Xu Shuwei (courtesy name Zhike) of Baisha. *Zhichai Shulu Jieti* records: Xu Shuwei's *Shanghan Ge* (Song on Cold Damage), three volumes, comprising one hundred chapters, all based on Zhang Zhongjing's annotations. There are also eighty-one chapters on treatment methods, thirty-six diagrams of Zhang Zhongjing's pulse methods, *Yi Shanghan Lun* (Supplement to the Treatise on Cold Damage), two volumes, and *Bianlei*, five volumes; these have not been seen.
The *Siku Quanshu Zongmu Tiyao* (Summary of the Complete Library of Four Treasuries) records: Xu Shuwei, courtesy name Zhike, was from Zhenzhou. He passed the imperial examination in the second year of Shaoxing. Physicians refer to him as Scholar Xu, though his official posts remain unknown. Examination reveals that *Shanghan Ge* is identical to *Baizheng Ge*; the discrepancy between three and five volumes is likely a textual error. *Yi Shanghan Lun* is synonymous with *Fawei Lun*. Xu Shuwei was from Yixing, Yangzhou. Orphaned in his youth, he studied diligently, reading widely across all books, with particular profundity in medicine. In the early Jianyan era, the rebel Zhang Yu captured Zhenzhou, followed by a severe epidemic. Xu Zhike visited households throughout the locality, diagnosed illnesses, and administered medicines, saving eight or nine out of ten patients. He served as an instructor in Huizhou and Hangzhou, later promoted to a central government rank. A shadow-printed Song manuscript bears a preface by Zhang Tan dated Gengyin of the Kaodao era. References also appear in *Duxing Zazhi*, *Xixi Conghua*, and Zhang Gao's *Yishuo*. Xu's *Leizheng Puji Benshi Fang* (General Beneficent Formulas for Differentiated Syndromes), ten volumes, is recorded in the *Book of Song: Bibliography*, *Shulu Jieti*, *Wenxian Tongkao*, and *Siku Quanshu*. I have only encountered it in *Shulu Jieti*. The *Maifa Leibian* has long been lost. The "eighty-one methods" likely correspond to the *Shanghan Jiushi Lun* (Treatise on Ninety Cases of Cold Damage) and *Baizheng Fawei* (Unveiling the Profound of Hundred Syndromes) recorded in Zhang Yuexiao's library catalog. Since the Yuan and Ming dynasties, this work has not been prominent.
It was not included in the *Siku Quanshu*, nor had it been seen by Ruan Yuan (Ruan Wenda) or Zhang Yuexiao. Only Qian Zunwang recorded it in his *Dushu Minqiu Ji* (Record of Books Read with Acute Perception). The Yuan edition collected by Qian Zunwang now belongs to me. Just as Confucius is to Confucianism, Zhang Zhongjing is to medicine. Just as the "Four Books" are to Confucian texts, the *Shanghan Lun* (Treatise on Cold Damage) is to medical texts. During the Song dynasty, scholars of this discipline produced various works: Cheng Wuji's commentary, Li Cheng's *Yaozhi* (Essentials), Wang Shi's *Zhengzhi* (Diagnosis and Treatment), Han Zhihe's *Weizhi* (Subtle Principles), Pang Anchang's *Zongbing Lun* (General Discussion on Diseases), Zhu Yizhong's *Huo Ren Shu* (Book That Revives People), and Qian Wenli's *Baiwen Ge* (Song on Hundred Questions). Although each had its strengths, Xu Zhike's work best captures their essence. The *Baizheng Ge* uses seven-character rhymed verses, comprehensive in meaning yet concise in language; the *Fawei Lun* explores the subtle and profound, achieving insightful and spiritual understanding. This invites admiration for the depth and profundity of Xu Zhike's learning, which surpasses those with superficial skills or narrow perspectives. In the Xinhai year of the Wanli era (Ming Dynasty), a commercial edition by Qiaoshantang combined them into four volumes. Compared with the Yuan edition, the Ming version not only altered the appearance significantly but also contained numerous interpolations and alterations. This is a common flaw in Ming printing, particularly egregious in medical texts. Fearing it might mislead quacks and endanger lives, I have re-engraved the Yuan edition to facilitate its widespread dissemination. May future students of medical literature, seeking Zhang Zhongjing's teachings through this text, avoid being ridiculed for neglecting their profession.
