 The action of Convocation as a deliberative body began in 1861, when, at its own request, the Crown licensed it to amend the twenty-ninth of the canons of 1603 on the subject of sponsors, and although no result followed, new canons were passed in 1865, 1887 and 1892.Apart from such general authorizations the Crown also possesses the right to submit definite business to the consideration of Convocation.This is done by "Special Letters of Business", a method used in 1872 and in 1907, in submitting the reports of the ritual commissioners to its consideration.
