The purpose of this note is to present a solution to a problem posed informally by A. Wilkie at the 1977 ASL meeting in Wrocław: Formulate "the cardinality of the universe is not exactly five" as a Horn sentence. Although this solution is not new -- I found it and M. Morley found another solution during the same meeting -- continuing sporadic inquiries about it suggest that its publication may be appropriate, even at this late date.
