Abstract :
The success of the San Juan Conference (Submillimeter II) has assured the continuance of the series. They will be held alternately, hereafter, in Europe and in North America. Thus Submillimeter III will be held at the University of Surrey, Guildford, England, March 28 - April 1, 1978. Guildford is just 30 minutes, by train, southwest of London´s Waterloo Station. Then, Submillimeter IV will be held again in North America, December 10-15, 1979. By choosing such dates and locations, it has been shown that a foreign conference need not be as prohibitively expensive as when held at a big city hotel in high season.
