Thus wemay refer the osteophyte, in anindividual case, to simple inflamma-tion, to iheumatic or gouty inflam-mation, to syphilis, to new growths,or other causes. The diffused and fibre-reticularosteophyte of Lobstein, or whatEokitansky terms the velvety villousosteophyte, forms an osseous layerinvesting a bone that is otherwisehealthy, sometimes removable, some-times firmly soldered to it; it com-monly presents the colour of thebone, or it may be discoloured ; by alens it is found to present a furrowedsurface, or to be composed of minuteupright spiculse; the small channelswhich separate the osseous ridgesbeing in the direction of the vessels. Osteopkytes, oecupying the lowerevLd of the femur. The whole ex-terior of the bone is roug-liened bythe g^^owth of irregular plates andpointed processes of osseous sub-stamce. A large canal, formed byulceration, passes through the honejust above the condyles ; around thelower part of each condyle is abroad rim of new bone.

This variety is avery common accompaniment of in-flammatory affections of the bone—it is the one which Eokitanskyhas observed to occur in the skull in females dying shortly afterparturition, and which he has therefore called the puerperal osteo- 851 ENCIIONDROMA. l^liyte. The layer of new bone, he says, varies in thickness from avery thin film to half a line, and more ; generally occupies thefrontal and parietal bones, but is sometimes found covering thewhole inner surface of the cranial vault, and scattered in
