灵枢经·骨度 Bone Measurements
黄帝问于伯高曰：脉度言经脉之长短，何以立之？伯高曰：先度其骨节之大小、广狭、长短，而脉度定矣。
黄帝曰：愿闻众人之度。人长七尺五寸者，其骨节之大小长短各几何？伯高曰：头之大骨围，二尺六寸，胸围四尺五寸。腰围四尺二寸。发所覆者颅至项，尺二寸。发以下至颐，长一尺，君子终折。
结喉以下至缺盆中，长四寸。缺盆以下至𩩲𩨗，长九寸，过则肺大，不满则肺小。𩩲𩨗以下至天枢，长八寸，过则胃大，不及则胃小。天枢以下至横骨，长六寸半，过则回肠广长，不满则狭短。横骨，长六寸半。横骨上廉以下至内辅之上廉，长一尺八寸。内辅之上廉以下至下廉，长三寸半。内辅下廉，下至内踝，长一尺三寸。内踝以下至地，长三寸。膝膕以下至附属，长一尺六寸。附属以下至地，长三寸。故骨围大则太过，小则不及。
角以下至柱骨，长一尺。行腋中不见者，长四寸。腋以下至季胁，长一尺二寸。季胁以下至髀枢，长六寸，髀枢以下至膝中，长一尺九寸。膝以下至外踝，长一尺六寸。外踝以下至京骨，长三寸。京骨以下至地，长一寸。
耳后当完骨者，广九寸。耳前当耳门者，广一尺三寸。两颧之间，相去七寸。两乳之间，广九寸半。两髀之间，广六寸半。
足长一尺二寸，广四寸半。肩至肘，长一尺七寸；肘至腕，长一尺二寸半。腕至中指本节，长四寸。本节至其末，长四寸半。
项发以下至背骨，长二寸半，膂骨以下至尾骶，二十一节，长三尺，上节长一寸四分分之一，奇分在下，故上七节至于膂骨，九寸八分分之七。此众人骨之度也，所以立经脉之长短也。是故视其经脉之
在于身也，其见浮而坚，其见明而大者，多血，细而沉者，多气也。
Huangdi asked Bogao: 'The chapter on Vessel Measurements speaks of the length of the channels — how were these established?' Bogao replied: 'One first measures the size, breadth, and length of the bones and joints, and from this the measurements of the vessels are determined.'
Huangdi said: 'I wish to hear the standard measurements for the ordinary person. In a person seven feet five inches in height, what are the sizes and lengths of the bones and joints?' Bogao replied: 'The circumference of the great bone of the head is two feet six inches; the circumference of the chest is four feet five inches; the circumference of the waist is four feet two inches. The area covered by hair, from the crown to the nape, measures one foot two inches. From the hairline downward to the chin measures one foot — this is the final figure by which a person of good proportion is reckoned.'
From the laryngeal prominence downward to the center of the supraclavicular fossa measures four inches. From the supraclavicular fossa downward to the xiphoid process measures nine inches; if it exceeds this, the lung is large, and if it falls short, the lung is small. From the xiphoid process downward to the level of the navel measures eight inches; if it exceeds this, the stomach is large, and if it falls short, the stomach is small. From the navel downward to the pubic bone measures six and a half inches; if it exceeds this, the coiled intestine is broad and long, and if it falls short, it is narrow and short. The pubic bone itself measures six and a half inches. From the upper border of the pubic bone downward to the upper border of the inner condyle of the knee measures one foot eight inches. From the upper border of the inner condyle downward to its lower border measures three and a half inches. From the lower border of the inner condyle downward to the inner ankle measures one foot three inches. From the inner ankle downward to the ground measures three inches. From the popliteal crease downward to the ankle measures one foot six inches. From the ankle downward to the ground measures three inches. Thus, if the circumference of the bone is large, this exceeds the standard measure; if small, it falls short of it.
From the corner of the forehead downward to the great bone of the neck measures one foot. The portion running through the axilla that is not visible measures four inches. From the axilla downward to the free ribs measures one foot two inches. From the free ribs downward to the hip joint measures six inches. From the hip joint downward to the middle of the knee measures one foot nine inches. From the knee downward to the outer ankle measures one foot six inches. From the outer ankle downward to the prominence of the fifth metatarsal measures three inches. From that prominence downward to the ground measures one inch.
The breadth between the mastoid bones behind the ears measures nine inches. The breadth between the points in front of the ears at the ear gate measures one foot three inches. The distance between the two cheekbones measures seven inches. The breadth between the two nipples measures nine and a half inches. The breadth between the two hip bones measures six and a half inches.
The foot measures one foot two inches in length and four and a half inches in breadth. From the shoulder to the elbow measures one foot seven inches; from the elbow to the wrist measures one foot two and a half inches. From the wrist to the base joint of the middle finger measures four inches. From the base joint to its tip measures four and a half inches.
From the hairline at the nape downward to the first vertebra of the spine measures two and a half inches. From the vertebrae of the back downward to the coccyx there are twenty-one segments, measuring three feet in total; the uppermost segments each measure one and a quarter inches, with the remaining fraction lodged in the lower segments, so that the upper seven segments down to the first vertebra of the back measure nine and seven-eighths inches. These are the standard bone measurements for the ordinary person, by which the length of the channels is established. Therefore, in examining a person's channels
as they appear on the body: where they appear floating and firm, or bright and large, there is an abundance of blood; where they appear fine and deep, there is an abundance of qi.
