[Footnote 63: Ordinal adjectives agree in gender and number with the
noun they accompany or for which they stand. Final _o_ changes into _a_
for the feminine, and the plural is formed by adding _s_.]

"Primero," "tercero," and "Postrero" drop the =O= before a masculine
noun singular,[64] as--

El primer pedido: The first order.
El tercer lote: The third lot.
El postrer envio: The last shipment.

But--

La primera entrega (_fem._): The first delivery.

[Footnote 64: Eight words in all present this peculiarity, viz., uno,
alguno, ninguno, bueno, malo, primero, tercero, postrero (these last
two not always).]

After "vigesimo" ordinal numbers are generally substituted by cardinal
numbers, as--

La pagina veintidos: Page 22nd.

Dates are expressed by cardinal numbers instead of ordinal, as--

Madrid, 20 (de) Agosto (de) 1911: Madrid,
