" The said President, Council, and Fellows do therefore 

 humbly request your Lordships, to intercede with his 

 Majesty, that he would be most graciously pleased to 

 enable "them to carry the said design into execution, in 

 such manner, as to his Majesty in his great wisdom shall 

 seem proper.

This was read before the Treasury Board on 

 the 6th July, and a warrant for 800/. given to 

 enable the Society to send two persons to St. 

 Helena for the purpose of observing the transit 

 of Venus. The next petition proceeds from the 

 Astronomer Royal, who applies for additional 

 salary for bis assistant.

 Lords Commissioners of His 

 Majesty's Treasury. 



" The Memorial of the Rev* Nevil Maskelyne, 

 B.D., Astronomer Royal. 



" Humbly sheweth 

 " That the business of your Memorialist's office, in 

 making astronomical observations and calculations from 

 them, is very laborious, and cannot be executed by him- 

 self alone without the help of an able Assistant. 



" That your Memorialist (agreeable to the original in- 

 stitution of the Royal Observatory in the year 1676) is 

 allowed by Government only 20/. ty ann. for maintaining 

 an Assistant, which allowance is totally inadequate for 

 the purpose, and that Your Memorialist has been obliged 

 to increase it to 60/. out of his own pocket. 



" That, notwithstanding this, when by the instructions 

 of your Memorialist the Assistant becomes capable of 

 being useful to him, he finds his labors underpaid, and 

 leaves him. That this has repeatedly been the case, to 

 the great inconvenience as well as expence of Your Me- 

 morialist, and to the obvious detriment of the Service of 

 the institution. That his present Assistant is now about 

 to leave him on this account only. 



" That in the time of the Astronomers Royal, who pre- 

 ceded Your Memorialist, very considerable perquisites 

 arose to the Assistant from shewing the Royal Observa- 

 tory to strangers. But, that upon his appointment to be 

 His Majesty's astronomical Observator in the year 1765, 

 he was strictly forbidden under His Majesty's Sign 

 Manual, to suffer any money to be taken for shewing the 

 Royal Observatory, which injunction has been punctually 

 obeyed. 



" That Your Memorialist hopes, from the facts above- 

 mentioned, that Your Lordships will think it reasonable 

 that an augmentation should be made to the Salarv of 



the Assistant, which augmentation Your Memorialist 

 humbly conceives should not be less than 70/. a year.

 " We the underwritten, The President and Council of 

 the Royal Society, Visitors of the Royal Observatory, do 

 certify that we are satisfied of the truth of the factscon- 

 tained in this Memorial ; and are of opinion that the 

 augmentation desired for the Assistant is reasonable and 

 necessary for carrying His Majesty's most gracious inten- 

 tions for the benefit of Astronomy and Navigation into 

 execution, if your Lordships shall think fit.

This petition was read on the 14th March, 1771, 

 and again on the 16th May following; when my 

 Lords consented to recommend to his Majesty an 

 additional salary of 70/. a year, to be paid to the 

 assistant of the Astronomer Royal so long as the 

 said Astronomer should not suffer any money to 

 be taken for showing the Royal Observatory.

MATHEMATICAL BIBLIOGRAPHY. 

 (Continued from 2 nd S. viii. 466.) 



To the works of Theophrastus I might have 

 added five books Problemaium Cullectionis (Diog. 

 L., op.cit, p. 203., II. 22—3.), one (other?) book 

 Problemaium Colltctio (p. 204., 1. 25.), two Deduc- 

 tornm locorum (p. 202., 1. 20), one Solutiones (p. 

 204., 1. 16.), one de Democriti Astrologia (p. 202 , 

 11. 27—8.), one de Numeris (p. 204., 1. 19.), and 

 five on matters connected with music or arith- 

 metic, viz., one De Mensuris (p. 204 , 1. 20.), 

 three De Musicd (p. 204., 11. 16—17.), and one

 mentions the Harmoniacon of Metrodorus. Heil- 

 bronner (p. 286.) describes Geminus Rhodius as 

 the author of a work " De ortu Linearum Spira- 

 lium, Conchoidarum et earum Affect ionibus," 

 adding (p. 287. art. f.), " Hoc indicat Catalogus 

 librorum ex Barocciana Bibliotheca in Angliam 

 delatus."
