Yes of course you are right it is Siblly's Key to Physics and the Occult Sciences, Sad to say they are black and white print plates. Its a 6th edition pub, G J Jones, and my bound version also includes within the same binding an Appendix to Culpepper's Herbal, so obviously that last page is the last...

Hi Phillip

I too am a lucky possessor of an 1821 edition of Sibley's Key to Occut Physics. It is complete except it is missing a corner of page 76. Ive always wondered if there is more? If you need copies of any of the plates I think I have the complete set.
