During the year 1898, I published a short essay, On the Psychic Mechanism of Forgetfulness.- Sigmund Freud.

В течение год 1898 Я издавал коротко очерк на экстрасенс механизм забывчив. - Cигмунд Фроид.

published - past perfective aspect

short - accusative adjective; inanimate (no change)

essay - accusative noun; inanimate

Forgetfulness - genitive noun； there is no translation for forgetfulness in Russian so I invented.

Спасибо!
