How does the narrator describe his first encounter with the Swine-creatures?

The narrator first encounters a Swine-creature when he sees 'something peering in over the window ledge the eyes and ears alone showing' ^[1]. He initially thought it was a pig, but realized 'it was no pig God alone knows what it was' ^[1]. The creature had a 'grotesquely human mouth and jaw; but with no chin of which to speak' ^[1], a 'nose was prolonged into a snout' ^[1], and 'little eyes and queer ears' ^[1], giving it an 'extraordinarily swinelike appearance' ^[1]. Its face was an 'unwholesome white color' ^[1], and its eyes 'seemed to glow, at times, with a horribly human intelligence' ^[1].

The creature supported itself with 'two clawlike hands upon the windowsill' ^[1], which were 'of a clayey brown hue' ^[1], had 'four fingers and a thumb' ^[1], and were 'webbed up to the first joint, much as are a duck's' ^[1], with nails like 'talons of an eagle' ^[1]. The narrator felt a 'growing feeling of disgust, and some fear' ^[1], perceiving it as 'something superhumanly foul; something unholy' ^[1]. When he moved towards the window, 'the thing ducked and vanished' ^[1].
