Reference for Menachot 175:4

ר' אלעזר בר' צדוק אומר שנתות היו בהין וכו':

with the half-log measure! He replied, In that case, even according to your view, there was no need for the half-log measure, for since there was there the quarter-log measure it was possible to measure it with the quarter-log! But the following rule was established in the Temple: The vessel that served for one measure did not serve for another measure.<span class="x" onmousemove="('comment',' It was thus not permissible to measure a half-log by filling twice the quarter-log measure, similarly to measure a log and a half by filling the half-log measure three times.');">³</span>
