Responsa for Arakhin 43:12
אמר ליה
But R'Meir said "thirty days"? ' He answered: Thus did R'Hisda say: Many a beating did I receive from Abimi because of this [teaching]: If he is to proclaim on consecutive days, then [the period of proclamation] is thirty days; if on Mondays and Thursdays alone, then it is sixty days.<span class="x" onmousemove="('comment',' Until I learnt to understand its apparent contradictions. Abimi taught him that the property of orphans must be proclaimed on the view of R. Meir for sixty days. The disciple, however, knew the above cited Baraitha, that R. Meir limited it to thirty days and thus raised an objection against his Master's teaching. He had forgotten, however, the instruction offered by the same Master, according to which 'thirty days' referred to consecutive ones, whereas 'sixty days' were required if the proclamation took place only on Mondays and Thursdays. He could thus appreciate his colleague's bewilderment from his own experience of the difficulty.');"><sup>1</sup></span>
Maharach Or Zarua Responsa
A - Since upon demanding her ketubah she lost her right to sustenance, she can therefore collect neither her ketubah, nor her sustenance from the orphans who are minors. If, however, we follow the opinion mentioned in the Talmud, that we do enforce collection of a ketubah from minors, in order that the widow find it easier to remarry - then L is entitled to collect her ketubah.
