Rabbi Eliezer (alt., "Rabbi Meir" (MS Vienna)) says, [if] a Nazir and a corpse were under the stomach of a camel (i.e., such that the camel forms a "tent" over them), the Nazir does not shave on its account* account") (GR"A), and they are not liable on its account for defilement of the Temple and its consecrated objects.

Impurity that is placed in a wall, even half and half, and so too a herd of livestock, wild animals, and birds (see Mishnah Oholot 8:1), and so too living creatures* who walk single file, even if the head of this one is between the legs of that one, and the head of that one is between the legs of this one, the Nazir does not shave on their account, and they are not liable on their account for defilement of the Temple and its consecrated objects.

[If] one was pressed to work at a mill where there is an idolater or a menstruant, his clothes possess midras-impurity. What kind of a mill? Any that can (alt., "cannot" (Rash MiShanz)) be removed or pushed from its place. In the matter of corpse-impurity, his clothes are pure unless his clothes touch an opening of a handbreadth.

And what are "interlaced boughs" [that bring forth impurity and protect against it]? A tree which casts shade over the ground. Rabbi Yehuda says, we look at the lower ones as if they ascend to the top, and the upper ones as if they descend to the bottom, and if this one touches that one with an opening of a handbreadth, they bring forth impurity and protect against it. What are "protrusions"? A protrusion that projects out from a fence.* [If] they were placed on top of the fence, [Rabbi Yehuda says,] we look at them as if stones were pressed down on top of them. [If] they had rotted, we look at them as if they were metal stakes, and if they were thinned out [such that they became separated] from one another, if they could [nonetheless] support thin plasterwork, [they bring forth and protect against impurity], the words of Rabbi Meir. And the Sages say, medium plasterwork. Rabbi Yehuda says, if you pull a thread from one side to the other side and it touches, even if they do not intend it, behold, that blocks [the impurity].

Rabbi Yosei says, the ropes of a bed, and window-lattices protect [both] the house and the attic, unless the impurity crosses over to the other side. [If] they had placed [the ropes or the lattices] on top of a corpse in the open air, that which forms a tent opposite the perforation is impure, and that which is not opposite the perforation is pure, because impurity goes out in the same way that it entered. Rabbi Yehuda says, if they are [not] able to* support medium plasterwork, they do not protect. [If] they had placed [the ropes or the lattices] inside the house, behold, they protect, for I can look at the beams as if they descend and conceal [the empty space]. Rabbi Yosei says, [in regards to] a cupboard that is filled with vessels, and he threw it on top of an olive's-bulk of a corpse, they are impure, for if [the cupboard] was placed on top of a corpse in the open air, they would be pure.

A plank that is floating on the face of the water: [If] impurity is on the side, vessels that are on that side are pure. Rabbi Ya'akov says, we look at the plank as if it has descended and settled, and there is under it a handbreadth cubed. [If] impurity is on one side and vessels are on the other side, they are pure. Three houses, this one inside of that one, and half an olive's-bulk [of a corpse] in the inner one or in the middle one, and half an olive's-bulk in the outer one: The outer one is impure, [and] the inner one and the middle one are pure. [If] half an olive's-bulk is in the inner one or half an olive's-bulk is in the middle one, the inner one is pure, and the outer one and the middle one are impure. Said Rabbi Yehuda: I say one thing and they said one thing. I say to them, "Rabbi Eliezer concedes to Rabbi Yehoshua regarding two jars that are open inside a house, [that] it is impure. About what did they disagree? About two rooms of a house, for Rabbi Eliezer renders it impure, and Rabbi Yehoshua renders it pure." And they said to me, "Rabbi Yehoshua concedes to Rabbi Eliezer regarding two open rooms inside a house, that the house is pure. About what did they disagree? About two jars, for Rabbi Eliezer renders it impure and Rabbi Yehoshua renders it pure."
