Kimoto Published in the Present vo1ume a review article on the same subject. It describes exact results in detail, particularly for each metal. On the other hand, the present paper gives author's ideas, some of which are still speculative, related on the crystal growth in a smoke. Contents are as follows: 1) Macroscopic features of smokes. Factors determining the shape of smokes; Smoke of standard type. 2) Crystal growth of smoke particles. Thechnique of specimen collection for electron microscopy ; General characters of particles in each zone in a smoke; Condensation of metal vapour ; Vapour growth and coalescence growth ; Equillibrium form and growth form. 3) Crystal habits of fcc metals. Classification of habits; Truncation degree and the zone for each habit; Metals of the first and the second group p. 4) Crystal habits of bcc metals. Truncation degree of rhombic dodecahedron; Comparison with theoretical value. 5) Problems of A-15 structure. Two hypotheses; A- 1 5 structure and multiply twined particles; Experimental facts discouraging the second hypothesis (i) and (ii). 6) Metals with phase transformations. Be, Ti, Mn and Fe; Problems in the future.
