    Verf. behandelt das klassische Problem der Auflösung linearer Beobachtungsgleichungen nach der Methode der kleinsten Quadrate mit Hilfe von Bezeichnungen und Sätzen der Matrizentheorie. Er sieht die Beobachtungen als ein System von Vektoren an, ersetzt dieses durch das orthogonalisierte Normalsystem und zeigt auf diese Weise, daß die Matrix der gewöhnlichen Normalgleichungen eigentlich positiv definit ist. Er zeigt ferner die Verwandtschaft des Orthogonalisierungsverfahrens mit der \textit{Gauß}schen Substitutionsmethode. (IV~16.)
