Among the domesticated cats of India a spotted type of colouring, with a more or less decided tendency for the spots to coalesce into stripes, is very noticeable; and it is probable that these cats are derived from the spotted Indian desert-cat (F.
Usually the four subgenital cavities are distinct from each other (so-called tetrademnic condition), but in many Rhizostomeae, for example, Crambessa, the subgenital cavities join together under the subumbral floor of the stomach (so-called monodemnic condition) and coalesce to form a so-called subgenital portico placed on the oral side of the stomach, opening by four interradial apertures between the oral arms, that is to say, by the four primitive apertures of the subgenital pits.
In order that this finely divided slag shall rise to the surface and there coalesce with the overlying layer, the metal must be tranquil.
The former class undergo an incipient fusion or softening when heated, so that the fragments coalesce and yield a compact coke, while the latter (also called free-burning) preserve their form, producing a coke which is only serviceable when made from large pieces of coal, the smaller pieces being incoherent and of no value.
Many of the ideas set forth in earlier chapters here coalesce and find their consummation.
They are primitively paired, but often coalesce with each other more or less completely.
In the Ecaudata the radius and ulna coalesce into one bone.
In the family of the Diplograptidae the branches are reduced to two; these also coalesce similarly by their dorsal walls, and the polypary thus becomes biserial (diprionidian), and the line of the nema is taken by a long axial tube-like structure, the nemacaulus or virgular tube.
The same is true of the chains that coalesce with these near Cape Maisi and diverge northwesterly along the N.
It is seen that as the coupling k becomes small these two wavelengths coalesce into one single wave length.
