Well now, what are the effects of 20th or the 30th 16 generation? 17 because it takes us about four years to do an experiment, one 18 cycle and the subsequent cycles, but we are in the F-3 of som 19 of the groups now and we'll continue to grind along as long 20 as our energies hold out. 21 Well, I'm never going to live long enough to know FREMONT-SMITH: Do you want to tell us briefly that 22 fascinating story about the olfaction and how they do find 23 their way? 24 DONALDSON: 25 FREMONT~SMITH: 26 I keep watching the clock. It's so exciting I think we ought to just get a flaver of 1t, 27 DONALDSON: This is the work of Dr. Gorbman, Or. 28 Gorbran is the same chap that worked on the lodine uptake, 29 He has been doing memory pattern responses by taking the 30 salmon at the return and immobilizing them, lifting the skull 31 case off, putting probes in the olfactory lobes and then 32 dropping water on the olfactory nerves step by step down the 33 environment, L ree t Statford Warren DOBIUCLA 2S
