He was one of the Founding Fathers of the United States. Along with Samuel Adams and Thomas Paine, he is remembered as one of the most influential and radical advocates of the American Revolution and the republic. He was strong in his denunciations of corruption in government officials and his defense of historic rights June 6, 1799. In 1798 President John Adams nominated Henry special emissary to France, but he had to decline because of failing health. At the urging of Washington was elected to the Virginia House of Delegates as a Federalist. Three months prior to taking his seat in the state legislature, he died of stomach cancer on June 6, 1799, while at Red Hill, his family's large plantation.

"He's had his fill, when he the banquet leaves; / He's eat too much - his stomach heaves: / His rich and dainty food, how much he loathes, / The monstrous load now from his stomach flowers; / Nature's relieved - she teaches thus quite plain, / To eat too much of good things, brings much pain."—Barber, 1857

The Great Kangaroo, or 'boomer', or 'old man' (Macropus giganteus), attains a height of about five feet when standing upright. The fore limbs are very short, the hind long, with powerful, elongated feet. The fore limbs bear five digits armed with strong claws; the hind have only four. The head is small, with pointed muzzle and large ears. In accordance with its purely vegetarian habits, canine teeth are absent in the adult. The incisors are powerful, with a cutting edge. The fur is soft and woolly, and lighter in tint below than above. In the female there is a large pouch, in which the young are placed at birth, and become attached by their immature months to the nipples. At this time they are minute -- not more than an inch in length -- and, being to immature to suck, have milk pumped into them by their mother. They remain withing the pouch until able to run by the side of the parent. Not until some eight or nine months after birth are they left to shift entirely for themselves. Only one young one is produced at a birth. As regards internal organs, the stomach is large and complex, and the characteristic marsupial or epipubic bones are present.

A langur is a monkey of the genus Semnopithicus, which contains Asiatic forms characterized by slender build, very long tail, absence of cheek pouches, and the fact that the hind limbs are longer than the fore. The stomach is peculiar, for it is furnished with sacs or pouches; and the animals are largely herbivorous in diet, living chiefly upon leaves and young shoots. The true langur, or hanuman (S. entellus) is common throughout the greater part of India, and is in most places regarded as sacred by the Hindus.
