Zevahim 42: Again, Bloodwork

Following the dispute about pigul for a meal-offering, the Gemara investigates all the permitting factors for an offering to be accepted, before there are any considerations of pigul. Note that the sprinkling of the blood on the inner altar needs to be done correctly. Also, the count of blood worship tasks: 43 or 47 or 48? If the bloods of two animals mingles, there is room to be lenient, in terms of how many placements there were on the altar.
