In a few months he had recruited depleted regiments, supplied them with new clothing and eipiipmcnts, weeded out incom|H'tent ollicers. armed, equipped, and organized the mounted troops in a single corps, and in other ways had infused new life into the army. In his new command General Hooker failed, however, to show those qualities on the battle- field Avhich had 'distinguislied him as a corps and division commander. With the greater part of his army he advanced against General Lee, who then had a force half the size of his own. and who was stationed south of the Rappahan- no<'k, with the intention of attacking him in flank and rear and crushing him at one blow. His plans were somewhat deranged by high water and the failure of his cavalry under Stone- man to cut Lee's conimunications.

While the fighting was hottest, on Afay .Sd. Hooker was stunned, a pillar against which he was leaning having been struck by a cannon-ball. The dis.i.strous result was largely due to his vacillation and his inability to cope with an emergency. (See CiiAXCrT.i.nns- VTt-LE. Battle of.)

He was born at Glasgow, where he obtained the degree of M.D. in 1839. He im- mediately thereafter renounced the pursuit of medicine for that of botany, and joined the Ant- arctic expedition of the Krrhu.s and Terror. ^Tien he returned, in 1843, he brought 5340 spe- cies of jdants, which, with those discovereil on the voyages of Captain Cook and other travelers, are discussed in six quarto vohnncs under the titles of Flora Aniarclicti. Flora A'or(r ZrInntU(e, and Flora Ta-stmania" (1844-60), works which won him an eminent position in science. In 1847 he undertook a three years' expedition to the Hima- layas, ujxin which he made large collections, which, joineil with those of his friend. Dr. Thom- son, of the Botiinical Gardens, Calcutta, aggre- gated nearly 7000 species. His Tlimalniiini Jour- nals (2 vols., 8vo. 18.52 and 1854) contain the narrative, of this expedition, and the J'hoiloilen- drons of the ffikkim-Uimalnjia (1840-51) illns- iTate the most remarkable additions which he made on this occasion to ornamental garden jdants. With Dr. Thomson he undertook a Flora Indira (vol. i.. 8vo. 1855), the first volume of which, containing only a few orders, remains a fragment. Half of the volume is occupied with a dissertation on botanical geography, a depart- ment of science to which he paid special attention in various works. He afterwards again under- took a Flora of Rritifsh India, which was eoni- pleted in 1874. In 1871 he made an expedi- tion to Morocco, ascended the Great .Atlas, the summit of which had never before been reached by a Eviropean. and brought back a valuable collection of plants.
