Prescription 3823 President ly collected and published (1845) in Eng- land as Critical and Historical Essays, and in America as Biographical and Critical Mis- cellanies. In 1826 Prcscott decided to devote ! himself to the writing of Spanish history, a ! decision undoubtedly influenced by the lee- j tures of George Ticknor on Spanish litera- ture ; and in that year he began his first great historical work, Ferdinand and Isabella. He then began The Conquest of Mexico, the most popular of his works, which appeared in 1843, and which added still further to his reputation. The Conquest of Peru, a sequence to The Conquest of Mexico, was begun in 1844, and published in 1847. Later came the Reign oj Philip 11. In 1850 Prescott visited England and the Continent, and was everywhere enthusiastic- ally received. In addition to his reviews and his four great historical works already men- tioned, Prescott wrote a Life of Charles Brockden Brown (1833) for 'Sparks' Library of American Biography/ a memoir of John Pickering (1848) for the Massachusetts His- torical Society, and a continuation of Rob- ertson's Charles the Fifth (1856). As a whole, his writings have stood the test of time, and are still the best histories of the events with which they deal. They have appeared in var- ious editions, and have been translated into several languages. Prescription, a physician's formula for his prescribed medicines. Formerly written entirely in Latin, now Latin is usually em- ployed only in names of ingredients used. It is only by their botanical or chemical names that drugs can be definitely indicated, but the directions are now written in English, Prescription. In the most general sense of the term the acquisition or extinction of legal rights by lapse of time. More specifical- ly, however, in our legal system the term is limited to the acquisition by long and unin- terrupted use of the various classes of rights known as rights in another's land. Both in the United States and England twenty years' use is now generally declared by statute to be necessary for the acquisition of a legal right. Presentment. In law, technically, the ac- tion of a grand jury in taking notice of a crime of their own knowledge, where a bill of indictment has not been urged by the pub- lic prosecutor. In its broadest sense it in- cludes the finding of an indictment, and the presentment of a matter before any public body for its consideration. President of the United States. The chief executive chosen for a tezm of four years by an electoral college. In case of death, removal, resignation or inability, his place is taken by the Vice President. Under the Con- stitution the President, by and with the con- sent oi the Senate, is empowered to make treaties, to appoint ambassadors and foreign ministers. The President is commander-in- chief of the land and naval forces of the United States. The power of direction over the executive departments was not clearly recognized by early Congresses. The act of 1789 creating the Treasury Department con- templated the direct responsibility of the head of that department to Congress. In cre- ating the Postal Department, also, Congress failed to prescribe presidential direction. In his struggle with the United States Bank President Jackson, through successive re- movals of secretaries of the Treasury who refused to adopt his policy, definitely estab- lished the control of the President over all the executive departments. General control over the administration is exercised through the issue of ordinances or executive regula- tions. Thus there are organized codes of reg- ulations for the post office, the consular serv- ice, the army and navy, etc. Such regula- tions are sometimes issued by express au- thority of Congress; sometimes as an exer- cise of the executive power. The constitutional legislative powers of the President are the veto power; the power to lay before Congress communications re- lative to the state of the nation and to re- commend such legislation as he may deem expedient; and the power to summon Con- gress in extraordinary session and to ad- journ it in case the two houses fail to agree upon a date of adjournment. All measures and resolutions voted by Congress, excepting a motion to adjourn, must be submitted to the President for approval; if he disapprove of such measures, a two-thirds vote in Con- gress is required for enactment. He is subject to impeachment by the Senate for treason or other high crimes or misdemeanors. Upon the expiration of his term of office he becomes liable for wrongful acts committed in his term of office. In case of death of both Pres- ident and Vice President elect, there is no constitutional or statutory provision for fill- ing the office of President for the succeeding term. Constitutional qualifications for the Presidency are citteenship acquired by Am- erican birth, 14 years* residence in the U. S., and an age of not less than 35 years. His
