An interesting legend in the South Pacific tells us "Exprimit Globus hic noster quicquid Geographia recens exObservationibus fide dignis suppeditat tam in situ locorum plurium, quam in terrarum novarum etiam mariumque ambitu.
It has an author and date legend, reading "Globus coelestis ex Catalogo Brittanico et De la Caillii observationibus ad annum 1800 cura Soc.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "observationibus" in a variety of sentences. We hope that you will now be able to make sentences using this word.
