Intelligence has been received from Jamaica to the 7th March.
The late attempts of Lord MULGILLYE, the Governor, to put down the Colonial Unions, have excited the fiercest anger of the planters. They characterize his conduct as in a high degree tyrannical and oppressive. Several of the commanding-officers of the Island Militia have been dismissed for signing resolutions, adopted at meetings of the Unions, reflecting upon the measures of Government. It is said that the Commissioners of Public Ac- counts, at a private meeting, passed a resolution not to assign any funds for the payment of the Governor's salary. Some of the Magistrates have refused to serve ; and private letters describe the Colony as being altogether in the most disorganized state that can well be imagined. It would be serving these men according to their deserts, if they and their slaves were left to settle their quarrels without the in- tervention of British grenadiers.
