those of the ape or monkey, as also are, 34. The transverse apophyses of the vertebræ of the neck, and the sixth and seventh vertebræ. 35. The vertebræ of the neck are not perforated as in apes, but entire as in man. 36. The vertebræ of the back and their apophyses, are the same as in man; and in the lower vertebræ, there are only two inferior apophyses, but in the apes there are four. 37. As in man there are only five lumber vertebræ, but in monkeys there are six or seven. 38. The spinal apophyses of the lumber vertebræ are straight as in man. 39. The _os sacrum_ is composed of five vertebræ, as in man, but in apes or monkeys of only three. 40. As in man, the _coccix_ is composed of four bones, and not perforated, whereas in apes, it is composed of a greater number of bones, all of which are perforated. 41. In the orang-outang, there are only seven true ribs, and the extremities of the false ribs are all cartilaginous and articulated with the vertebræ; but in apes and monkeys, there are eight true ribs, and the extremities of the false ribs are osseous, and their articulations are placed in the intestines between the vertebræ. 42. His iternum is broad like that of man, but which is narrow in monkeys. 43. The bones of the four fingers are thicker than those of apes. 44. The thigh bone is like that of man. 45. The rotula is round, long, and single, but double in the apes. 46. The heel _tarsus_ and _metatarsus_ are like those of man. 47. The middle toe is not so long as that of the apes. 48. The _obliquus inferior capitis_, _pyriformis_, and _biceps femoris_ muscles, are like those of man, but which are different in the apes or monkeys.
