gary w hart

O.E. heorot "male deer," from P.Gmc. *kherut- (cf. O.H.G. hiruz, O.N. hjörtr, Ger. Hirsch), perhaps from PIE base *ker- "horn" (cf. L. cornu "horn," cervus "deer," Welsh carw "deer"). Now, a male deer after its fifth year. Hartshorn "ammonium carbonate" is O.E. heortes hornes, so called because a main early source of ammonia was the antlers of harts.
