387 Ab hoc itaque tempore series observationum Coelestium interrupta est, finisque impositus 38 annorum observationibus.

Nocte, quam ultimam habuit, per delirium, quo omnia suavissima fuere, creberrime hæc verba iteravit, quasi qui carmen texit.

Quem procul dubio ceu colophonem operibus suis addere, eaque his verbis Posteritatis memoriæ & usibus dedicare voluit.

The following table gives the places for 1586 (anno 1585 completo) of Tycho's nine standard stars (Progymn., p. 204), and their positions for the same epoch, computed from those of Bradley for 1755, with the proper motions of Auwers (Neue Reduction der Bradley'schen Beobachtungen, vol. ii.). The differences between Bradley and Tycho are shown in the next table. The effect of refraction (which Tycho thought insensible above Zen. Dist. 70º or Declination -14º for Uraniborg), is seen at a glance, and I have therefore in the last column given the difference of declination corrected for mean refraction.
