'This  is the burial of asses'? — According to R. Johanan they are made in the corner[s].  But, surely, the chambers would touch  each other? — R. Ashi replied: One can make them deeper.  For if you would not say so,  how can four grottos be constructed according to R. Simeon? Surely [some of] the chambers [of adjacent grottos] would be touching  each other! But [this. you would say, can be avoided] by digging [the overlapping chambers] deeper [than the others];  in this case also, [the touching of chambers may be avoided] by digging [the corner chambers] into the wall deeper [than the adjacent ones]. R. Huna the son of R. Joshua stated: The [affected chambers in the] four grottos, according to R. Simeon, were made in the shape of palm-wigs.  But this [statement of R. Huna b. R. Joshua is [to be] rejected.  For, it is to be observed, every cubit square has a diagonal of a cubit and two fifths [approximately]. [The diagonal of the square formed by the adjacent walls of any two grottos] measures eleven cubits and a fifth,  [approximately]. Is not the number of the chambers eight?  How, [then], is it possible [to make eight [chambers]  in [a width of] eleven [cubits] and a fifth? But that [statement] of R. Huna b. R. Joshua must be rejected. If you like, it may be said: As R. Shisha son of R. Idi [referred the case, infra.] to miscarriages, [so] here also [the chambers in question are for the burial] of miscarriages. We have learnt elsewhere [in a Mishnah]:  If a corpse is found  lying [in a grave] in the usual manner.  both the corpse and the earth surrounding it are to be removed.  [If] two [corpses, in similar conditions, are found], they and the earth surrounding them are to be removed.
