Gittin

'A jet of water [from a jug] or water flowing down a slope, or dripping water, does not form a connection so as to make [the water] unclean  or clean?  — The question is still required for the case where the dripping is considerable.  But regarding this also we have been taught that where the dripping is considerable, it does form a connection. — Perhaps this dictum refers only to a mikweh,  and follows the opinion of R. Judah: For we learnt: 'If a mikweh contains exactly forty se'ahs of water and two persons bathe in it, if they both are in the water together they are both clean, but if one enters after the other has left, the first is clean but the second not'.  R. Judah said that if the feet of the first were still touching the water [when the second entered]. the second is also clean. R. Jeremiah said: It has been laid down that if a person plunges the greater part of his body in water drawn [through a pipe],  or if three logs of such water are poured over the greater part of the body of a clean person, he is unclean.  R. Jeremiah then propounded: Suppose he plunges half of his [body into such water] and three logs of it fall on the other half, is he unclean? This question was left unanswered. R. Papa said: It has been laid down that if a sick person had a seminal emission and nine kabs of water are thrown over him, he is clean. R. papa then asked: If he dips half his [body in water] and [water is] thrown over the other half, is he clean? This question was also left unanswered. IF ONE DECLARES, 'IT WAS WRITTEN IN MY PRESENCE AND THE OTHER, etc.' R. Samuel b. Judah said in the name of R. Johanan: This rule applies only to the case where the Get was not brought by both as joint bearers, but if it is brought by both of them
