The managers resolved that on November 2 Mr. Davy should begin a course of lectures on Tanning; that he should have leave of absence in July, August, and September, to learn the practical part of the business; and that respectable persons of the trade, if recommended by proprietors of the Institution, should be admitted gratis. In order to obtain more support Count Rumford drew up in his own name a letter to be sent as a circular with a printed fly-leaf. The heading of it ran thus: Being desirous of becoming a member of the Royal Institution of Great Britain, I request that Count Rumford would propose me to the managers of the said Institution as a candidate for election in the class pointed out in the column below, in which my name is subscribed. 1st class proprietors, who up to May 1802 pay seventy guineas; 2nd class life subscribers, who pay twenty guineas; 3rd class annual subscribers, three guineas. The letter states that, as the Institution will certainly become more interesting and more useful in proportion as it is made more complete and more extensive in all its numerous details, it is very desirable that as great a number as possible of respectable individuals should be induced to unite in its support and interest themselves in its prosperity; and then, after mentioning that its plan has been much praised abroad, it says: And if some persons in this country, influenced by misrepresentation or by groundless apprehensions or other motives, have been withheld from giving to the undertaking their countenance and support, the character, reputation, and distinguished rank of many of those who have been most active in promoting it, and who certainly may be supposed to be best acquainted with its nature and tendency, and above all the ostensible patronage of our most gracious Sovereign, who has given so many proofs of his solicitude to encourage useful improvements and to discourage dangerous and doubtful innovations, ought to be sufficient to relieve the doubts of all, and to recommend the Royal Institution of Great Britain to the support of all those who take pleasure in contributing to the diffusion of useful knowledge and the encouragement of industry and ingenuity. The postscript says: Any one or more gentlemen of your acquaintance whom you shall recommend will be proposed to the managers, and will no doubt be elected. Soon after the third number of the Journal was edited by Rumford alone. It contained a paper on the ‘Use of Steam as a Vehicle for Conveying Heat from one Place to another,’ by Count Rumford, and ‘An Account of a New Eudyometer,’ by Mr. Davy.
