    entire calculus, gained thirteen grains and a half; the fmaller, which was a frag- ment, loft two grains. This difference in the operation of mephitic water on the two calculi, cannot be attributed to a dif- ference in their component parts, as the fame large calculus, infufed in Robertfon's urine, had formerly loft five grains; and the fame fmall one had formerly acquired half a grain. Such uncertainty in the refult of experiments, accurately made, muft throw much doubt on the lithon- triptic powers of mephitic air. Dr. Lamphiers experiments, related in his thefls, printed in the year 1778, afford the fame conclufion as the preced- ing for, on expofing a calculus to me- phitic air, he found that it gained an addition of weight; and, in two experi- ments where calculi were infufed in me- phitic water, the calculus became heavier in one, and lighter in the other. In Dr. Plunket's experiments, published laft autumn in his inaugural differtation, nei- ther mephitic air, which had no commu- nication with the exernal air, nor his own urine,
