The title `Tractatus de Conclusionibus Astrolabii' is suggested by the wording of the colophon on p. 223.  But a better title is, simply, `Tractatus de Astrolabio', or `Treatise on the Astrolabe', as the `Conclusiones' only occupy the Second Part of the work; see p. 188.  Indeed MS. F. has `Tractatus Astrolabii'; see p. 233.  MSS. B. and E. have the singular title -- `Bred and mylk for childeren.'
