✦ Synopsis

In a communication which was entitled "Notes on Geisler's Theory of Phase Transformations with Special Reference to Indium-Thallium Alloys" [l], the authors have discussed the experimental evidence in relation to a double shear mechanism of transformation from the cubic to the tetragonal form which was proposed by Bowles and coworkers [2] and to a modified nucleation and twinning mechanism proposed by Geisler and Martin [3]. The authors state in a footnote to the communication that the terms "first" and "second" shear are used purely for convenience in describing the crystallographic change and are not meant to imply any physical resolution of the atom movements into two components. They subsequently assume the position of defending the twoshear mechanism of transformation.

There is no disagreement in the general observation that the A.
