DESCRIPTION:Co-authors: Robert Murtagh (Trinity College Dublin)\, David Wh
 yte (Trinity College Dublin)\, Steve Tobin (Trinity College Dublin)\, Deni
 s Weaire (Trinity College Dublin) \n\nWe develop the Z-Cone Model\, in ter
 ms of which the energy of a foam may be estimated. It is directly applicab
 le to a structure in which every bubble has Z equivalent neighbours\, but 
 can be applied more approximately to other cases.The energy (i.e. surface 
 area) may be analytically related to liquid fraction. It has the correct a
 symptotic form in the limits of dry and wet foam\, with pre-factors depend
 ent on Z. In particular\, the variation of energy with compression in the 
 wet limit is consistent with the anomalous behaviour found by Morse and Wi
 tten (1993) and Lacasse et al.(1996)\, with a prefactor proportional to Z.
