It's not exactly a matter of knowing who said it but where was said it, or rather, in which of his books did Raymond Lully (Ramon Llull) write the following: “Sub conservatione formae specificae salva anima.” Any help?

I had difficulty finding out too much concrete information about this person. In fact, check out what is said about "Raymond Lully" on this webpage (it won't let me copy and paste)

Thanks for the tip!...
