In 1943, Horstmann and Tatlock reported detecting cold agglutinins in the serum of patients with primary atypical pneumonia. Fifty years after Landsteinerâs findings, the term âcold agglutinin diseaseâ was coined by Schubothe.
Mulattoes were the direct offspring of plantation rapes. Slave masters often threat the female slaves if they resist the masterâs desire of having intercourse. If they fought back, the female slaves will be whipped, will be beaten up, or worse of all, will be killed.
It was thought right to hold heathen Africans in slavery; but, as mulattoes must be part Christians, a knotty question came up, for the English law in relation to serfdom declared the condition of the child must be determined by that of the father. The Virginia law opposed this doctrine in favor of the slave-holders.
