of indefinite anatomical metaphors in a discussion of political facts, of necessity imply that the author of the "Case," had had a medical education. The two most famous among modern biological sociologists were educated, one as a civil engineer, the other as a clergyman, but both make use of such figures of speech as Gookin employed, and the putative author of the twelfth chapter of First Corinthians was by trade a tent maker. On the other hand Gookin, upon the first page of his vindication, distinctly claims the sole authorship of "The Great Case." He says: "Whilst anything of Reputation might have been the effect of writing the Case of Transplantation, I was content to take the labour to myself and leave the good to others: This was the reason of silencing my name at first. But now what I intended for good is come to be thought so ill, I must leave that resolution and assert my own act.… But though I did not think then fit to put my name in Print, yet did not that Trifle steal out in so clandestine a way as that the Parent was hid from all, but being laid at my door, I owned it." Accordingly I regard Gookin as the author of "The Great Case of Transplantation," and have not included it among Petty's Economic Works.
