Aš atverčiau knygą kur pakliuvo.
Raidžių formos man buvo niekur nematytos.
Puslapiai apšiurę, raidės neryškios, tekstas ėjo dviem skiltimis.
Puslapiai apšiurę, raidės neryškios, tekstas ėjo dviem skiltimis.

Ir mažas paveikslėlis, toks, koks pasitaiko žodynuose:
plunksna nupieštas inkaras, bet lyg negrabia vaiko ranka.
Puslapiai apšiurę, raidės neryškios, tekstas ėjo dviem skiltimis.
