The curves at this stage depend on the attitude of the child while sitting or being carried for example, the arm bones become bent in children who paddle about the floor with the aid of their arms; and in a child who lies on its back with the lower limbs everted, the weight of the limb may lead to curvature of the neck of the femur coxa vara.
Hear Maecenas: "Debilem facito manu, Debilem pede, coxa, Lubricos quate dentes; Vita dum superest, bene est." And Tamerlane, with a foolish humanity, palliated the fantastic cruelty he exercised upon lepers, when he put all he could hear of to death, to deliver them, as he pretended, from the painful life they lived.
Thus in his discussion of dislocation of the femur Roger says: Si crus a coxa sit disjunctum, eadem sit cura quam et in disjuncturam brachii et cubiti diximus, etc. The general subject of fistulae is treated at considerable length on folio 205b, and fistula lachrymalis and fistulae of the jaw receive special attention in their appropriate places.
THE PELVIS OR HAUNCH is formed by a single bone, the coxa that in the foetus may be divided into three bones. These are the ilium, pubis and ischium. It belongs to the class of flat bones. Anteriorly it is flattened from before to behind and directed inward and upward. The external angle is rugged and is generally termed the angle of the haunch.
These men have impaled moths and dissected, magnified and located brain, heart and nerves. After finishing the interior they have given to the most minute exterior organ from two to three inches of Latin name. From them we learn that it requires a coxa, trochanter, femur, tibia, tarsus, ungues, pulvillus, and anterior, medial and posterior spurs to provide a leg for a moth.
In Heterocerus, which belongs to another family, the rasps are placed on the sides of the first abdominal segment, and are scraped by ridges on the femora. In the Carabidae I have examined Elaphrus uliginosus and Blethisa multipunctata, sent to me by Mr. Crotch. Rasp. c. Coxa. f. Femur. t. Tibia. tr. Many Lamellicorns have the power of stridulating, and the organs differ greatly in position.
