ספקו טמא אמרת לן מר
<b><i>GEMARA</i></b>. Rami b. Samuel and R. Isaac son of Rab Judah learnt the tractate of <i>Niddah</i> at R. Huna's. Rabba son of R. Huna once found them while they were sitting at their studies and saying: The chamber is within, the ante-chamber is without and the upper chamber is built above them,<span class="x" onmousemove="('comment',' Cf. supra n. 7.
