A normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood. Having more than 450,000 platelets is a condition called thrombocytosis; having less than 150,000 is known as thrombocytopenia.
THE APPRENTICESHIP SYSTEM. The term 'emancipation' which was used to describe the Act of 1833 passed by the British Government to put an end to slavery in the British Empire, is ambiguous and misleading. Slaves were not freed in the sense that they were given unrestricted control over their freedom of movement.
In fact during the apprenticeship period (1834-1838) and in 1839, a number of persons of African descent came to Jamaica as free labourers. Also, in the following 25 years about 10, 000 free labourers of African origin came to the island.
