A Self-Descriptive Crossword Puzzle

Each of the entries in the crossword is of the form NUMBER NAME | BLANK SPACE | LETTER(“S”) and describes the number of times the named letter appears in the completed grid. For example, if the grid contained a single “Z,” then one of the answers would be “ONE Z,” with a space between ONE and Z. Plurals are indicated by adding an “S,” as in “THIRTEEN ES.” Spaces are also counted here, so if there were 19 spaces, then one entry would be “NINETEEN S” with two spaces before the “S.” Can you find the unique way of completing the grid so that it describes itself as indicated?
