cerebral parts; this idea fucceeded. I continued then to 



raife my pile upon thefe new fupports : I was aftonifhed and 



much more impatient to perceive nothing at the thirtieth couple. 



Obftinately bent on fucceeding or being convinced that my 



opinion was erroneous I perfifled and continued to heighten 



my pile ; I did not perceive the leaft effecT; until I had added 



the fortieth pair. Encouraged by this fuccefs, I redoubled At the fiftieth 



my attention and was thoroughly convinced of the exigence ^ pe r Ce f ve d 



of the tafte at the fiftieth couple. Neverthelefs I continued and at the fix- 



increafing the pile to the fixtieth, and the evidence of its ticth decifive * 



effects was moft decifive. 



Such were my difagreeable but curious experiments.
