[anno 1790. 



for which place he accordingly embarked in the beginning of November. Pre- 

 vious to this however he finished the first copy of his paper ; iDut it was much 

 hurried toward the latter part, and not rendered so perfect as the General would 

 undoubtedly have made it with more time and better health. He returned to 

 England in April 1790, and the paper was sent to the press before the end of the 

 same month. Unfortunately the General did not live to see the printing quite 

 completed; he corrected indeed all the sheets except the last 3 ; but without com- 

 paring his manuscript copy with the original papers and observations. Several 

 errors which had been discovered in the course of the printing, together with the 

 obscurity of the account in certain parts, induced some of the General's friends, 

 members of the r. s., to request, after his decease, that the whole might be 

 revised by a competent person, who should compare it with the original docu- 

 ments, correct such mistakes as might be discovered, and illustrate whatever re- 

 quired further explanation. No one could be found so proper for this task as Mr. 

 Dalby, the gentleman of whom the General makes such honourable mention in 

 his paper, and who, having assisted in all the operations, was as well acquainted 

 with every part of them, as the General himself. The result of Mr. Dalby 's 

 examination is the following remarks ; which being much too long for insertion 

 in the list of errata, where only the errors of the press are noticed, is here added 

 separately, by way of appendix. C. Blagden." 



This task was accordingly very ably executed by Mr. Dalby, and his correc- 

 tions printed, amounting to 11 quarto pages of the volume, under the title of 

 Remarks on Major-General Roy's account of the Trigonometrical Operation, &c.
