Thomas Browne,
Observations on eggs
“ Others, considering the rare contingency, might conceive it a casuall stayne from some uterine tincture while it lay in the matrix in a softer covering before exclusion, yet in the progresse it may receave impression from some exudation from the vessells of the matrix, whereby sometimes wee meet with egges with bloody tinctures on the shell, & since we receaved this of soe notable a figure, wee have seen another of the same tincture confusedly dispersed through the greatest part thereof without making out any figure. ”
