A letter was received also within this period from the society established at Philadelphia, accompanied with documents in proof of the good effects of the manumission of slaves, and with specimens of writing and drawing by the same. In this letter the society congratulated the commitee in London on its formation, and professed its readiness to cooperate in any way in which it could be made useful.
During these sittings, a letter was also read from Dr. Bathurst, now bishop of Norwich, dated Oxford, December the seventeenth, in which he offered his services in the promotion of the cause.
Another was read, which stated that Dr. Horne, president of Magdalen College in the same university, and afterwards bishop of the same see as the former, highly favoured it.
Another was read from Mr. Lambert, fellow of Trinity College, Cambridge, in which he signified to the commitee the great desire he had to promote the object of their institution. He had drawn up a number of queries relative to the state of the unhappy slaves in the islands, which he had transmitted to a friend, who had resided in them, to answer. These answers he purposed to forward to the commitee on their arrival.
Another was read from Dr. Hinchliffe, bishop of Peterborough, in which he testified his hearty approbation of the institution, and of the design of it, and his determination to support the object of it in parliament. He gave in at the same time a plan, which he called Thoughts on the Means of Abolishing the Slave-trade in Great Britain and in our West Indian Islands, for the consideration of the commitee.
At the last of these sittings, the commitee thought it right to make a report to the public relative to the state and progress of their cause; but as this was composed from materials, which the reader has now in his possession, it may not be necessary to produce it.
On the twenty-second and twenty-ninth of January, and on the fifth and twelfth of February, 1788, sittings were also held. During these, the business still increasing, John Maitland, esquire, was elected a member of the commitee.
As the correspondents of the commitee were now numerous, and as these solicited publications for the use of those who applied to them, as well as of those to whom they wished to give a knowledge of the subject, the press was kept in constant employ during this period also. Five thousand two hundred and fifty additional Reports were ordered to be printed, and also three thousand of Falconbridge's Account of the Slave-trade, the manuscript of which was now finished. At this time, Mr. Newton, rector of St. Mary Woolnoth in London, who had been in his youth to the coast of Africa, but who had now become a serious and useful divine, felt it his duty to write his Thoughts on the African Slave-trade. The commitee, having obtained permission, printed three thousand copies of these also.
During these sittings, the chairman was requested to have frequent communication with Dr. Porteus, bishop of London, as he had expressed his desire of becoming useful to the institution.
A circular letter also, with the report before mentioned, was ordered to be sent to the mayors of several corporate towns.
