丁卯十一月弟子许半龙敬书于中医专校
昔者淳于意尝自录治验，上之史氏，以示治病之要，乃后世医案之嚆矢也。元明以降，此风大炽，而可
传之作，寥若晨星。迫于近今，更渺不可得。盖驳杂而不醇，验与不验，不复计焉。而箴于海上乃得丁师甘仁，
师上追轩岐之奥旨，中发仲景之原理，晚得叶、王之治法，实昏夜之烛，空谷之音也。惜以诊务纷繁，席无暇
暖，著作甚鲜，所存者惟医案数卷而已。文孙济万世兄，绳武祖德，不忍见手泽之湮没，校 付刊，嘉惠后
学，其功诚不浅，而吾师之作，自此传矣。箴椎鲁无文，不敢赞一辞，敬缀数言，聊志景仰云尔。
丁卯季秋门人陶可箴谨序
许半龙自从我从中医专科学校毕业后，便整理行装回到芦墟。乙丑年春天，丁甘仁老师写信召唤我，让我在广益善堂进行义诊。我自觉学识浅薄简陋，心中惶恐，觉得自己难以胜任。不久之后，千顷堂书肆向我索取《外科学大纲》，打算将其刻印出版，我本来不敢自信（没有把握），于是就去向丁老师请教。老师慷慨地说：“我自从寓居上海以来，跟随我学习的人不下数百人，但在外科这一领域，深入研究的人却很少。如今这部书刊行于世，不仅是我们门派的荣耀，也是对病患的巨大造福，意义非常深远。”第二天，丁老师为我写了序言，言辞情意深挚，对我多有鼓励和称赞。第二年六月，我为了避暑暂时回到家乡，丁老师就在月底去世了，唉，真是可悲啊！今年冬天，他的孙子丁济万，将丁老师的外科医案，委托给我参校，我生性疏懒，去拜访请示的日子很少，但丁老师并不认为我怠慢，反而宽容待我，又加以褒奖赞许。如今才过了几天，他深厚的深情和慈祥的面容，仿佛还在眼前，而丁老师的墓上草已枯荣几度了，所以我不能不说话，这不仅是出于对泰山崩塌、梁木朽坏（指德高望重者去世）的悲痛，也是为了保存知己之感。
丁卯年十一月，弟子许半龙恭敬地写于中医专科学校
从前，淳于意曾经亲自记录治疗验案，呈交给史官，以展示治病的关键，这是后世医案的开端。元朝、明朝以后，这种风气大盛，但能够流传下来的作品，稀少得像早晨的星星一样。到了近代，更是渺茫不可得。因为内容驳杂而不纯粹，有效与无效，不再被计较。而在海上（指上海）地区，才得以遇到丁甘仁老师。老师向上追溯黄帝、岐伯的深奥旨意，中间阐发张仲景的原理，晚年得到叶天士、王孟英的治疗法则，实在是黑暗中的蜡烛，空谷中的回音（指指引方向的明灯）。可惜因为诊疗事务繁杂，席子还没坐暖就要起身忙碌，著作很少，所留下的只有几卷医案罢了。丁济万世兄，继承祖先美德，不忍心看到先人手泽（指手迹或遗物）被埋没，校对后付梓刊印，嘉惠后学，他的功劳确实不小，而我的老师的著作，从此得以流传了。我陶可箴愚钝无文，不敢多说什么，恭敬地写上几句话，姑且表达敬仰之情罢了。
丁卯年秋季，门人陶可箴恭敬地作序
Xu Banlong: After graduating from the Traditional Chinese Medicine Specialized School, I packed my bags and returned to Luxu. In the spring of the Yichou year, Master Ding sent a letter summoning me to provide free medical consultations at Guangyi Shan Tang (Guangyi Benevolent Hall). Feeling my knowledge and learning were shallow and inadequate, I was filled with trepidation, fearing I could not bear the responsibility. Shortly thereafter, the Qianxingtang Bookstore requested my "Outline of External Medicine" for publication. Lacking confidence in my own work, I sought guidance from Master Ding. He generously stated, "Since residing in Shanghai, I have had hundreds of students, yet few have delved deeply into surgery. The publication of this volume will not only bring glory to our school but also greatly benefit patients, which is no small matter." The next day, Master Ding wrote a preface for me, his words sincere and affectionate, offering much encouragement and praise. In June of the following year, while I temporarily returned to my hometown to escape the summer heat, Master Ding passed away at the end of the month. Alas, how sorrowful! This winter, his grandson, Mr. Jiwan, entrusted me with reviewing Master Ding's surgical medical cases. Being naturally lazy, I rarely visited him for advice, yet Master Ding never considered it disrespect; instead, he tolerated me kindly and offered further praise. Only a few days have passed since then, yet his deep affection and kind countenance remain vivid before my eyes, while the grass on Master Ding's grave has already grown and withered several times. Thus, I cannot help but speak; this is not merely out of the grief for the collapse of Mount Tai and the rotting of the beam (metaphors for the loss of a revered elder), but also to preserve the feeling of having a confidant.
Written respectfully by disciple Xu Banlong in November of the Dingmao year at the Traditional Chinese Medicine Specialized School.
In ancient times, Chunyu Yi recorded his treatment cases and submitted them to the historians to demonstrate the essentials of treating diseases, marking the beginning of medical case records for later generations. Since the Yuan and Ming dynasties, this trend became widespread, yet works worthy of transmission were as rare as morning stars. In recent times, they are even more elusive and scarce. This is because many texts are mixed and impure, with little regard for whether the treatments were effective or not. However, in the Shanghai region, we were fortunate to encounter Master Ding Ganren. Master looked up to the profound principles of Huangdi (Yellow Emperor) and Qibo, elucidated the theories of Zhang Zhongjing, and in his later years, adopted the therapeutic methods of Ye Tianshi and Wang Mengying. He was truly a candle in the dark night and an echo in an empty valley (a guiding light). Regrettably, due to the complexity of his clinical duties, he rarely had time to sit still, leaving few written works; what remained were only a few volumes of medical cases. Mr. Jiwan, inheriting his ancestor's virtue, could not bear to see these handwritings buried in oblivion, so he proofread and published them, benefiting future scholars. His merit is indeed significant, and through this, my master's works will be transmitted. I, Tao Kezhen, being dull and unskilled in writing, dare not add a word, but respectfully append a few lines to express my admiration.
Respectfully prefaced by disciple Tao Kezhen in the late autumn of the Dingmao year.
