The secular variations in longitude differences among several observatories were determined, but it is hard to consider that these results are literally due to continental drift. The large standard deviations of the data of longitude differences show the existence of external systematic errors in time observations.

RÉSUMÉ

Des variations séculaires des différences de longitudes entre plusieurs observatoires ont été trouvées; mais il est difficile de les considérer comme réellement dues ä des dérives continentales. Les grands écarts-types sur les différences de longitudes montrent l'existence d'erreurs systématiques externes dans les observations de l'heure.
