小儿之耳聋口哑，乃连带相关之证也。盖小儿必习闻大人之言，而后能言；故小儿当未能言时或甫能言
时，骤然耳聋不闻，必至哑不能言。是以治此证者，当专治其耳聋。然耳聋之证有可治者，有不可治者。其
不可治者，耳膜破也。其可治者，耳中核络有窒塞也。用灵磁石一块口中含之，将细铁条插耳内，磁铁之
气相感，如此十二日，耳之窒塞当通。若仍不通，宜口含铁块，
耳际塞磁石，如此十二日耳中之窒塞当通矣。
犀黄，诚如兄言为西黄之误。盖牛黄之好者，出于高丽，因
高丽之牛大，故所出之黄亦最美（从前高丽清心丸甚佳，以其有牛黄也），特别之曰，东牛黄，而其价亦
较昂；青海西藏之地，亦多出牛黄，其成色亚于东牛黄，故又别之曰，西牛黄，而其地原有犀，遂又误西
为犀也。紫石英，弟恒用之，治女子不育甚效。其未经 者，其色紫而透彻，大小皆作五棱者佳。盖白石英
属阴，紫石英属阳，阴者宜六棱，阳者宜五梭。至钟乳石，蛇含石，皆未用过，不敢置论。
接骨之方甚多，然求其效而速者，独有一方可以公诸医界。
方用甜瓜子、生菜子各一两，小榆树的鲜嫩白皮一两，再加真芝麻油一两，同捣如泥，敷患处，以布缠
之。不过半点钟，觉骨接上即去药，不然恐骨之接处起节。自得此方后，门人李××曾用以治马甚效，想
用以治人亦无不效也。且试验可在数刻之间，设有不效，再用他方亦未晚也。
人之筋骨相着，然骨以刚而易折，筋以韧而难断，是以方书中治接骨之方甚伙，而接筋之方甚鲜也。
诸家本草多言旋复花能续断筋，《群芳谱》谓 根能续断筋。 根愚未试过，至旋复花邑中有以之治牛马断筋
者，甚效。其方初则秘而不传，当耕地之时，牛马多有因惊骇奔逸被犁头铲断腿上筋者，敷以所制之药，
过两旬必愈。后愚为其家治病，始详言其方。且言此方受之异人，本以治人，而以治物类亦无不效。因
将其方详录于下。
方用旋复花细末五六钱，加白蔗糖两许，和水半茶杯同熬成膏。候冷加麝香少许（无麝香亦可），摊
布上，缠伤处。至旬日，将药揭下，筋之两端皆长一小疙瘩。再换药一帖，其两小疙瘩即连为
一，而断者续矣。若其筋断在关节之处，又必须设法闭住，勿令其关节屈伸，筋方能续。
按∶《外台秘要》有急续断筋方，取旋复花根洗净捣敷创上。
日一，二易，瘥止，是取其鲜根捣烂用之也。因药局无旋复花根，是以后世用者权用其花，想性亦相近，故能奏效。
小儿的耳聋和口哑，是相互关联的症状。因为小儿必须经常听到大人的说话，之后才能学会说话；所以小儿在还不会说话或刚刚能说话的时候，如果突然耳聋听不见声音，必然会导致失语不能说话。因此治疗这种病症，应当专门治疗其耳聋。然而耳聋的病症有可以治疗的，也有不可以治疗的。不可以治疗的，是因为耳膜破裂了。可以治疗的，是因为耳中有结节和络脉堵塞。用一块灵磁石含在口中，将细铁条插入耳内，利用磁铁的气场相互感应，这样持续十二天，耳朵中的堵塞应当会通畅。如果仍然不通畅，应该口含铁块，在耳际塞入磁石，这样持续十二天，耳中的堵塞应当会通畅。
犀黄，确实像您所说，是西黄的误写。大概牛黄中好的，产自高丽，因为高丽的牛大，所以产出的牛黄也最精美（从前的高丽清心丸非常好，就是因为它含有牛黄），特别称之为“东牛黄”，而且价格也比较昂贵；青海、西藏等地，也多出产牛黄，其成色比东牛黄稍差，所以又另外称为“西牛黄”，而那里原本就有犀牛，于是就把“西”误写为“犀”了。紫石英，我平时经常使用，治疗女子不孕非常有效。未经过处理的紫石英，颜色紫红且透彻，大小都呈五棱形的为佳。大概白石英属阴，紫石英属阳，阴性的宜六棱，阳性的宜五棱。至于钟乳石、蛇含石，我都未曾用过，不敢妄加评论。
接骨的方子很多，但寻求见效快的，只有一个方子可以公之于医界。方子用甜瓜子、生菜子各一两，小榆树鲜嫩的内皮一两，再加真芝麻油一两，一起捣烂如泥，敷在患处，用布缠绕固定。不过半个时辰，感觉骨头接上后就去掉药物，不然恐怕骨头的连接处会长出骨节。自从得到这个方子后，门人李××曾用它来治马，效果很好，想用来治人也一定没有无效的道理。而且试验可以在几个时辰之间进行，如果有不生效的情况，再用其他方子也不晚。
人的筋骨相连，但是骨头坚硬而易折，筋柔韧而难断，所以在方书中治疗接骨的方子非常多，而接筋的方子却很少。各家本草多记载旋复花能接续断裂的筋，《群芳谱》说某植物的根能接续断裂的筋。那个根我未曾试过，至于旋复花，县里有人用它来治疗牛马断裂的筋，效果很好。那个方子起初保密不传，当耕地的时候，牛马多有因受惊狂奔被犁头铲断腿上的筋的，敷上他制作的药，过了二十天必定痊愈。后来我为他家治病，才详细说明了那个方子。并且说此方是从异人那里得来的，本是用来治人的，用来治动物也没有无效的。因此将其方详细记录如下。
方子用旋复花细末五六钱，加白糖约一两，加水半茶杯一起熬成膏状。冷却后加入少许麝香（没有麝香也可以），摊在布上，缠绕包扎伤处。到了十天，揭下药，筋的两端都会长出一个小结节。再换一帖药，那两个小结节就会连在一起，断裂的筋就接续上了。如果筋是在关节处断裂，又必须设法固定住，不让关节屈伸，筋才能接续。
按：《外台秘要》中有急续断筋方，取旋复花根洗净捣烂敷在创面上。每天一次或两次更换，痊愈即止，这是取其鲜根捣烂使用的缘故。因为药局没有旋复花根，所以后世使用者权且使用其花，想其药性也相近，所以能奏效。
The deafness and muteness of children are symptoms that are interrelated. This is because children must be accustomed to hearing adults speak before they can learn to speak; thus, when a child who cannot yet speak or has just begun to speak suddenly becomes deaf and loses the ability to hear, it will inevitably lead to muteness and an inability to speak. Therefore, in treating this condition, one should focus specifically on treating the deafness. However, cases of deafness vary: some are treatable, while others are not. The untreatable cases involve a ruptured tympanic membrane (ear drum). The treatable cases involve blockages caused by nodules and collateral vessels within the ear. Place a piece of Magnetitum (Lingcishi) in the mouth, insert a thin iron rod into the ear canal, and utilize the magnetic interaction between them. Continue this for twelve days, and the blockage in the ear should clear. If it remains blocked, place an iron block in the mouth and insert a magnet near the ear. Continue this for twelve days, and the blockage in the ear should clear.
Xihuang (Calculus Bovis, 牛黄), as you correctly stated, is a miswriting of Xihuang (Calculus Bubali, 西黄). Generally, high-quality Calculus Bovis comes from Korea. Because Korean cattle are large, the Calculus Bovis produced there is the finest (the former Korean Qingxin Wan was excellent precisely because it contained Calculus Bovis). It is specially referred to as "Dong Niu Huang" (Eastern Calculus Bovis), and its price is relatively high. Qinghai and Tibet regions also produce much Calculus Bovis, but its quality is inferior to that of Dong Niu Huang, so it is separately called "Xi Niu Huang" (Western Calculus Bovis). Since these regions originally had rhinoceroses, the character "Xi" (West) was mistakenly written as "Xi" (Rhino). Ziyingshi (Fluorite, 紫石英) is something I frequently use, and it is very effective in treating female infertility. Unprocessed Ziyingshi that is purple in color and translucent, with five facets, is considered best. Generally, Baiyingshi (Quartz, 白石英) belongs to Yin, while Ziyingshi belongs to Yang. Yin substances ideally have six facets, while Yang substances ideally have five facets. As for Zhurushi (Stalactite, 钟乳石) and Shetanshi (Jaspidis Herba, 蛇含石), I have never used them, so I dare not comment.
There are many prescriptions for setting broken bones, but seeking one that acts quickly, there is only one prescription that I can share with the medical community. The prescription uses Tian Guazi (Melon Seed, 甜瓜子) and Sheng Caizi (Lettuce Seed, 生菜子), each one tael, along with one tael of the fresh tender inner bark of the small elm tree (Xia Yushu), plus one tael of genuine sesame oil. All ingredients are pounded together into a paste, applied to the affected area, and wrapped with cloth. Within half a shichen (one hour), once the bone feels set, remove the medicine; otherwise, there is a risk of callus formation at the fracture site. Since obtaining this prescription, my disciple Li XX used it to treat horses with great effect. I believe it will also be effective for humans. Moreover, the trial can be conducted within a few hours. If it proves ineffective, switching to other prescriptions would still be timely.
Human tendons and bones are connected, but bones are hard and prone to fracture, while tendons are tough and difficult to break. Therefore, while there are numerous prescriptions for setting bones in medical texts, prescriptions for healing severed tendons are rare. Most materia medica mention that Xuanfuhua (Inulae Flos, 旋复花) can heal severed tendons. The *Qunfang Pu* states that the root of a certain plant can heal severed tendons. I have not tried that root myself. However, in our county, people use Xuanfuhua to treat severed tendons in horses and cattle with good results. That prescription was initially kept secret. During plowing season, many horses and cattle suffer severed leg tendons due to panic and running away, getting cut by plowshares. Applying his prepared medicine leads to recovery within twenty days. Later, when I treated illnesses for his family, he detailed the prescription. He stated that this prescription was received from an unusual person, intended originally for human use, and is equally effective for animals. Therefore, I record the prescription in detail below.
The prescription uses five to six qian of fine powder of Xuanfuhua (Inulae Flos), added with approximately one liang of white sugar, and half a teacup of water, boiled together into a paste. After cooling, add a small amount of Shexiang (Musk, 麝香) (optional if unavailable), spread onto cloth, and wrap around the injury. After ten days, remove the medicine. Both ends of the severed tendon will grow small nodules. Apply another dose of the medicine, and the two small nodules will connect, healing the severed tendon. If the tendon is severed at a joint, it is necessary to immobilize the joint to prevent flexion and extension, allowing the tendon to heal properly.
Note: The *Waitai Miyao* contains an urgent prescription for healing severed tendons, which involves washing the root of Xuanfuhua, pounding it, and applying it to the wound. Change the dressing once or twice daily until healed. This utilizes the fresh root pounded into a paste. Because pharmacies do not stock Xuanfuhua roots, later practitioners substituted the flower, assuming the properties are similar, thus achieving efficacy.
