Captain de Starck, the gallant and worthy officer whose services, &c. have been recorded at p. 178, et seq. of Supplement Part I., is the inventor of an “Applicative Compass for taking Bearings on a Chart,” of which the following mention is made in “Nicholson’s Philosophical Journal,” vol. xii. p. 224:
