1) It has been evidenced in our animal experiments with matured rabbits that both autogenous and homogenous grafts are gradually absorbed whenever they are transplanted in any portion of the body if there are no physiological demands for the bone.
2) Autografts showed much better affinity with the tissue than heterografts. Albeit the less affinity of the latter, their attitude was by no means synonymous to the attitude of the sequestra, and their intolerability was gradually reduced with the lapse of the time. This phenomenon was not altered by either hemotype or salivary type.
3) In the case of homografts, the. attitude of the grafted bones was modiffed by preoperative serological preparation:
A. Previous injection of serum from the homogenous donator effected the maintenance of relatively physiological state on the grafted bone, whereas same procedure with serum from those homogenous or heterogenous species which are not the donators induced a trend toward marked absorption of the grafted bone.
B. There was a less absorption of the grafted bone in those which had previouslyundergone injection of serum of homogenous donator than in those which had not.
C. It was also noted that there was the most remarkable trend toward degenerative necrosis in those which had been previously treated by heterogenous serum injection. No relationship was found between these results and title of produced antigen or antibody.
