It may be interesting to insert some miscellaneous information which the gentleman communicated to this Editor in Oct. 1798, while he resided for a few weeks or months at Marazion, and which was imperfectly noted at the time. He received the whole of his education as an engineer under Mr. Benjamin Robins, F.R.S. Engineer-General to the East India Company, the well-known author of various mathematical tracts, and especially of a treatise on the principles of gunnery, the force of gunpowder, and on the resisting power of the air to bodies in swift and in slow motion. This treatise his pupil Mr. Call transcribed for the press; and no doubt he assisted in making those admirable experiments and mathematical deductions from them, which have given a new character to this important branch of military science, as well in respect to small arms, and more especially to rifled barrels, as to cannon and mortars, in reference to which Mr. Call made an additional improvement so as to discharge shells from long guns by placing the fusee internally, with its orifice concentric to the surface instead of projecting, and thereby securing it from injury as the shot rolls in passing out of the gun. He successfully defended Fort St. George at Madras; and in 1761 conducted the siege of Pondicherry, which ended in the capture of that place, the chief seat of the French power in India. Sir John Call also mentions as a curious circumstance, illustrative of the decisive effects produced by the well-directed fire of field artillery, that in a battle where he was present (query, was it Plassey?) a shell from an howitzer caused the explosion of a carriage containing gunpowder, which produced some confusion and disorder in the enemy’s line; the commander instantly ordered a charge, and the victory was decided. And he related another anecdote on a very different subject. That having with other amateurs of astronomy made preparations for observing the transit of Venus by constructing a temporary observatory on the flat roof of the government house at Madras, they waited with impatience after a long continuance of fine weather, for the important 3d of June 1761, when a most violent storm on the preceding night injured or destroyed their instruments so as to render any observation impossible; and, what added to their mortification and disappointment, a long continuance of fine weather succeeded this tempest. Whiteford is now the residence of his son Sir William Pratt Call, who was Sheriff of Cornwall in 1807, and has a family. The manor of Climsland Prior paid to the monastery at Launceston, the free tenants 8_s._ the conventionary tenants £6. 13_s._ 9_d._ The advowson of the living seems to have been appurtenant to the ancient duchy manor of Stokeclimsland.
