'Fig. 3. A geometric projection of the head end of a model of H87

(Univ. of Chicago Coll.), drawn by J. F. Didusch and reduced to 100 diameters. Upon it the otic and optic-crest primordia are plotted and represented by stippling. The densest areas indicate the position of sulci ; as. few. gang., aeousticofacial ganglion; cr. sul., neural-crest sulcus corresponding in this case to the position of the future Vth ganglion; f.b., forebrain; h.b., hindbrain; m.b., midbrain;, optic-crest primordium;, otic plate; s0m.I, first somite.
