Ps. cxxx. uox ecdesiae rogantis. 



B has uox ecdesiae regnantis. The reading of a is more in harmony with 

 the psalm. The translator of S seems to have noticed the incongruity, for he 

 adds iiel sandae niariae. It is unnecessary to suppose that regnantis, in spite 

 of the support of S, was in |3. It may be a scribe's misreading of rogantis. 



On the whole it may fairly be claimed that the balance of probability is 

 strono-ly in favour of the view that a was a descendant of /3, and that both 

 were ancestors of A. The correctness of this theory will be assumed in what 

 remains to be said. 



At last, after this long but not unnecessary preface, we come to the 

 rubrics of the Cathach Psalter (0). Here our sphere is more limited ; for C 

 contains, in whole or in part, only 76 psalms, and of eleven of these the 

 headings and liturgical notes are lost or illegible, and wholly irrecoverable.' 

 Thus we have 65 rubrics to consider. It appears that in at least 27 cases 

 the headings and liturgical notes are identical with those of a |3,,^ though in a 

 few rubrics, which are not completely legible, the identity is not absolutely 

 certain. There are also seven psalms in which C agrees with a, and probably 

 also with /3, though it differs from the existing text of B.' And finally, there 

 are sLx headings of C which agree with those of a, while B either gives no 

 rubric,* or relies on some authority other than j3,* and in which the text of j3, 

 therefore, cannot be ascertained. These facts, though they by no means 

 constitute the whole of the evidence, suffice to show that C belongs to the 

 same group as a and /3. A discussion of the remaining 25 rubrics may enable 

 us to give it its proper place in the group. 



Ps. xxxvi. hortatur rnoyscm ad fidcm demonstrans salutem ecdesiae credentem 

 monct ad fidci firtnamvntum. 



C (J stand alone, so far as I know, in the reading ad fidei firmamcniuTii, 

 though no doubt Tommasi copied from some MS. the words ad fidei firmitatem 

 which appear in his Collectio Argumeniorum.^ In « we have omnes for moysem 

 (C). But moysem has good support from other MSS.,' and the difficulty of the 

 reading would provoke emendation. C seems, therefore, to have the original 

 text from which a deviated. /3 was perhaps identical with either C or a.
