Je was op zoek naar: johannæum (Engels - Spaans)

the unlucky word would not come out. at the johannæum there would have been a laugh.
¡el enrevesado vocablo no quería salir cuánto se hubieran reído del pobre profesor en el johanaeum!

he was professor at the johannæum, and was delivering a series of lectures on mineralogy, in the course of every one of which he broke into a passion once or twice at least.
era profesor del johannaeum, donde explicaba la cátedra de mineralogía, enfureciéndose, por regla general, una o dos veces en cada clase.

the fact is, that during the course of his lectures at the johannæum, the professor often came to a complete standstill; he fought with wilful words that refused to pass his struggling lips, such words as resist and distend the cheeks, and at last break out into the unasked-for shape of a round and most unscientific oath: then his fury would gradually abate.
en sus explicaciones en el johannaeum, se detenía a lo mejor luchando con un recalcitrante vocablo que no quería salir de sus labios; con una de esas palabras que se resisten, se hinchan y acaban por ser expelidas bajo la forma de un taco, siendo éste el origen de su cólera.
