 Dear all,
 	I would like to ask whether some of you know about
 the symposium on "Metal in Ammonia" that held every two years.
 Could you please, if you know, direct me to the information
 about this symposium Colloque Weyl on where and when this symposim
 will be held for the year 1997 so that my colleague will prepare
 to participate this meeting.
