There was also a chemical analysis conducted:
"Analytical Certificate.—Analytical Laboratory, 203, Oxford-street, Sydney. To C. W. M'Carthy, Esq., M.D., Elizabeth-street, —I, the undersigned, analytical chemist, do hereby certify that I received, on the 29th day of June, 1889, from C. W. M'Carthy, Esq., M.D., a sample of chipping and powders for analysis, and have analysed the same, and declare the result of my analysis to be as follows: —No. 1 (chipping): Carbonate of lime. No. 2 (powder): Carbonate of lime and phosphate of lime. Phosphate of lime is the form in which phosphorous is found in bone ash or bone earth. As witness my hand this 29th day of June. 1889. (Signed) James Mayne, F. O. S., F.R.M.S., M.P. S. Witness, H.P."
"I certify that the 'powder,' analysed by, Mr Mayne on 29th June, 1889, and found by him to contain carbonate and phosphate of lime, the latter in the form of 'bone ash or bone earth,' was portion of the substance gouged and filed by me from the stump of the right armbone of the petrified human remains lately exhibited in Sydney. I further certify that the 'chopping,' analysed by him on the same day, and found to be composed of carbonate of lime only, was a portion chiselled off the site of the soft fleshy tissue of the right shoulder of the petrified figure. "(Signed) CHARLES W. M'CARTHY, M.D., F.R.C.S.I., 223, Elizabeth-street, Hyde Park, Sydney, June 30th, 1889,"

Can anyone help me make sense of it? Could results like this come from a marble carving (treated with various chemicals to get an aged effect) or does it suggest tampering by the good Dr McCarthy (since he was the one who supplied the sample)?
