Volume IX contains three articles, two of which are on superfluid hydrodynamics and the third on glasses. As an illustration of the comments made above, Glaberson and Donnelly's article on vortices in superfluid 4He has had to be restricted even within this particular subject, and several topics of great current interest in vortices have had to be excluded. The problem of the generation of vorticity in helium II is still not understood, and will doubtless form the subject of a future article. A further illustration of the increasing length to breadth ratio is provided by Hall and Hook's article on the hydrodynamics of superfluid 3He which is made additionally intricate by the complex structure of its order parameter. It builds on the Brinkman and Cross review of spin and orbital dynamics in Volume VIIa but now it has been necessary to restrict it to orbital dynamics; again, we expect to deal with spin dynamics in superfluid 3He in a future article. Finally, Hunklinger and Raychaudhuri's article on glasses provides some balance to what would otherwise have been a volume on superfluid helium, and reminds us that some disordered condensed systems, which used to be shunned by many experimental and theoretical physicists, are now regarded as tractable problems...
