' Robins wa.s one of the most accurate and elegant mathematical writ'^rs that our language can boast of; and he made 

 more real improvements in artillery, the Hight and the resistance of projectiles, than all the preceding writers on tliat 

 subject.'— Dr. Charles Hutton, F.R.S. 



Uia Di scour sr on . . . Flurions {v. II) is a reply to Bp. Berkeley's Analyst (r. Xos. 347 and G144-.0, antf), and 'a very 

 clear, neat, and elegant performance ' {Dr. Hutton). He was an unsuccessful comi^etitor for the professorship of fortification 

 and gunnery at R.M.A. Woolwich against John Mailer (A ov. 12268-73 a«/e}, whose powerful influence secured him the 

 position. Robins's work on gunnery is said to have been due to this disappointment, 'as he wanted to show to the 

 world, what sort of man he was that they had rejected.'— F. Nos. 4044-5 anti.
