Comparative embryological data presented in the paper support an idea that chondrification of the mesenchyme does not begin until the latter becomes condensated. Size and density of the skeletogenous rudiments are not the same in different vertebrates. As a rule, in animals with much of the mesenchyme (chondrichthyans, amniotes), the prochondral condensations contain more cells and have both greater mass and density. The distribution pattern of the mesenchyme is also significant for the future development of the cartilaginous elements which at the earlier stages grow largely by the recruitment of surrounding mesenchymal cells. Such kind of the growth mode is probably most similar to the cartilage fusion mode: both processed take place in the absence of the perichondrium. The non-skeletal dense structures influence on the development of the cartilaginous skeleton primarily by determining distribution pattern of the mesenchyme, particularly the condensation of skeletogenous cells. THe growing cartilages themselves can influence mechanically on the surrounding organs.
