Formation of the human foetus: five figures, showing the development from five months to nine months gestation. Colour engraving, by J. Pass after D. Dodd, 1794.

"For the exact position of the child in the womb, during these last three months, as well as the former, see the corresponding figures in the two annexed engravings, the whole of which were correctly drawn from real foetuses, extracted from the wombs of different women, and are now preserved for the inspection of the curious, in Rackstrow's Museum, to which I beg leave to refer the inquisitive reader"--Sibly, loc. cit., pp. 58-59
