    great ischiatic notch, and lastly the posterior portion of the tuberosity of the ischium. Of how many distinct bones is the oa innominatum originally composed? Three, the ilium above, the ischium directly below, the pubis in front of the Last, and rather below the first. At what points are these bones consolidated into one at a later period of life? In the acetabulum, or co- tyloid cavity, at the pectineal eminence and at the middle of the ischiopubic ramus. At about what period of life, does this consolidation take place ? The age of puberty. What are the principal articulations or symphyses of the pelvis? One for the two pubic bones to each other in front, and. one for each ilium to the sacrum behind. What is the mode of articulation of the symphysis pubes ? The two articular surfaces arc applied to each other, and sustained firmly in that position, by strong ligamentous fibres, before and behind. Under- neath, the fibrous arrangement is so abundant, a< to give to it the character and name of sub-pubio liga- ment. Is the symphysis pubes of the adult female suscejit i- ble of spontaneous separation, or of having om trcmity moved upon the other ? There are strong reasons for believing that no perceptible degree of motion can be effected in a healthy condition of the parts. What is the character of the posterior or sacro-iliac symphysis? The sacrum is placed like an inverted key-stone at the top of an arch, between the two iliac bones; strong bands of ligamentous fibres extend across from the sacrum to the ilium on each side, and thus a strong fibro cartilaginous symphysis is effected. Is there a bursa, or synovial sac, found in either of these symphyses ? In the symphysis of the pubes, there is to be seen an approximation to a bursa ; it is however far from complete. In each of the sacro-iliac
