Rab Judah said in the name of Rab: If the windpipe was perforated [with many holes] like a sieve, they are reckoned together in order to make up the greater part.<span class="x" onmousemove="('comment',' I.e., the holes are considered as being adjacent and in a line, and if then it appears that the greater portion of the circumference of the windpipe is severed the animal is trefah.');"><sup>1</sup></span>
R'Jeremiah raised an objection It was taught: If there was one long hole in the skull, or even if there were many small holes in it, in either case the hole or holes are computed to make up the measure of a hole the size of a [surgeon's] drill.<span class="x" onmousemove="('comment',' And if the hole is of the size of a surgeon's drill the skull will no longer convey uncleanness to men or vessels that are in the same 'tent' or under the same roof; V. Ohol. II, 3.');"><sup>2</sup></span>
We therefore see that if the measure is that of a hole the size of a drill, several small holes are reckoned together so as to make up this measure; similarly we ought to say here, inasmuch as the measure<span class="x" onmousemove="('comment',' Where the windpipe was perforated, as distinct from where it was merely severed. V. infra 54a.');"><sup>3</sup></span>
that several small holes shall be reckoned together to make up a hole the size of an issar? - He [R'Jeremiah] obviously overlooked the dictum of R'Helbo which he reported in the name of R'Hama B'Guria on the authority of Rab: Holes with loss of substance are reckoned together to make up the measure of a hole the size of an issar, but holes without any loss of substance are reckoned together to make up the greater part [of the circumference].<span class="x" onmousemove="('comment',' And Rab Judah was referring to holes without any loss of substance.');"><sup>5</sup></span>
R'Isaac B'Nahmani enquired of R'Joshua B'Levi: What is the law if the windpipe was perforated like a sieve? - He replied: They have said: Holes with loss of substance are reckoned together to make up the measure of a hole the size of an issar, but holes without any loss of substance are reckoned together to make up the greater part [of the circumference].
What is the test in the case of a bird?<span class="x" onmousemove="('comment',' If there were several holes in it with loss of substance, or if a strip of the windpipe was removed. The measure of an issar obviously cannot apply to a bird too, since the entire width of its windpipe does not amount to an issar.');"><sup>7</sup></span>
- R'Isaac B'Nahmani said: It was explained to me by R'Eleazar thus: It<span class="x" onmousemove="('comment',' Sc. the portion of the windpipe that is perforated with several holes, including even the solid substance between the holes (Rashi) .');"><sup>8</sup></span>
R'Papa said: And in order to remember this [test] think of a sieve.<span class="x" onmousemove="('comment',' Which is a cavity covered over by a network of small holes; here too the portion perforated must be placed over the cavity of the windpipe.');"><sup>10</sup></span>
R'Nahman said, if the windpipe was lacerated in the shape of a door,<span class="x" onmousemove="('comment',' I.e., a Portion of the windpipe was cut around on three sides but attached on the fourth side (Rashi) . According to Alfasi and Maim., 'The windpipe was perforated from side to side', i.e., there were two holes in the windpipe exactly opposite each other. It is to be observed that 'like a door' is not found in MS.M. nor in the text of Alfasi. Moreover there is considerable doubt whether this case refers to a bird or cattle.

Raba said: 'The nethermost lobe' really means the uppermost lobe,<span class="x" onmousemove="('comment',' It is clear that the top lobe of the lung is meant but the description of it will vary according to the position of the animal. If the animal is suspended by its hind legs the top lobe is really the nethermost.');"><sup>15</sup></span>
It is that portion which looks down upon the ground; on top<span class="x" onmousemove="('comment',' This is the better text, so found in Tosef Hul. IX and in many MSS.; so also in Maim. In cur. edd. the directions are reversed.');"><sup>20</sup></span>
Two ribs from the two sides, on this side and on that, are cut away with it.<span class="x" onmousemove="('comment',' According to Rashi, one rib is to be cut away on each side; however, in the Tosef. loc. cit. and in Maim. it is expressly stated that two ribs must be cut away on each side.

R'Samuel B'Nahmani said: And in order to remember this think of the bag in which the brain lies.<span class="x" onmousemove="('comment',' This is a mnemonic for remembering the second opinion, namely, that the inner membrane is the vital one. There is a play upon the word t,hhj , which means 'life' and also 'a bag'.');"><sup>24</sup></span>
Rabbah B'Bar Hana said in the name of R'Joshua B'Levi: The same is to be observed with the stones.<span class="x" onmousemove="('comment',' I.e., the testicles of an animal are also invested by two coverings, an inner and outer membrane, like the brain.');"><sup>25</sup></span>
