Copies were sent also to every member of both Houses of Parliament.
The Society, in the same year, anxious, that the conduct of its members should be consistent with its public profession on this great subject, recommended it to the quarterly and monthly meetings to inquire through their respective districts, whether any, bearing its name, were in any way concerned in the traffic, and to deal with such, and to report the success of their labours in the ensuing year.

Orders were also given for the reprinting and circulation of ten thousand other copies of 'The Case.' In the year 1785, the Society interested itself again in a similar manner.
For the meeting for sufferings, as representing it, recommended to the quarterly meetings to distribute a work, written by Anthony Benezet, in America, called, A Caution to Great Britain and her Colonies, in a short Representation of the calamitous State of the enslaved Negros in the British Dominions.

This book was accordingly forwarded to them for this purpose.

On receiving it, they sent it among several public bodies, the regular and dissenting clergy, justices of the peace, and particularly among the great schools of the kingdom, that the rising youth might acquire a knowledge, and at the same time a detestation, of this cruel traffic.

In this latter case, a deputation of the Society waited upon the masters, to know if they would allow their scholars to receive it.
