The "l" in "coln," and the "h" in "John" are silent. It is a case of In. by sound. To the ear the sound of "Con." is like that of "Jon." =ANdrew Johnson.= } In. =Ulysses S. GrANt.= } "An" in Andrew and in Grant has the same sound. =UlyssES S. Grant.= } In. =Rutherford B. HayES.= } "Es" in Ulyss_es_ and in Hay_es_ is the same in _spelling_--but not in sound. It must be _noticed_, as it is the weakest of all. A stronger tie has heretofore been given. =Rutherford B. HAYes.= } Con. =James A. GarFIELD.= } There is a strong association between Hay of _Hay_es and and the field of Gar_field_, as in the familiar word "Hayfield." =James A. GARfield.= } In. =Chester A. ARthur.= } In "Gar" and "Ar" there is a strong In. by sound. =Chester A. ArTHUR.= } In. =GroVER Cleveland.= } Between "thur" and "ver" there is a clear In. by sound. =Grover ClevelANd.= } Con. =BenjAMin Harrison.= } There is a fair In. by sound between "an" and "am;" but as they are alphabetically reversed, it makes a case of Con. reversed. =BenjAMin Harrison.= } In. & =Grover ClevelANd.= } Ex. Here "am" and "an" occur in alphabetical order, and is a case of In., and "jam," meaning pressing together, and "cle(a)ve" meaning to separate, are opposites, hence it is also an example of Exclusion. Let the student, as in the case of the other groups, recall this list several times, and each time revive the relation by which each pair of names was cemented together, and after this let him recall this list several times both ways without reviving the cementing relations, and finally let him recall several times, both ways, the entire series of Presidents from Washington to Cleveland, and from Cleveland to Washington. REMARKS. 1. This group furnishes the notable fact that two Presidents (Lincoln and Garfield) were assassinated while in office. 2. Another peculiarity of this group is that, for the first time since the days of Washington, there was a widespread discussion and effort made to push the claims of a President (Grant) for a third term. 3. This group contains the name of the grandson (Benjamin Harrison) of William Henry Harrison, of the second group. The only other instance of relationship between the Presidents was in the case of John Adams and his son, John Quincy Adams of the first group. 4. This group contains the name of the only President (Andrew Johnson) who was ever sought to be impeached. The prosecution failed to convict, having lacked one vote of the number necessary for a conviction. 5. Grover Cleveland affords the first instance where the two terms of a President are separated by the full term of another President (Benjamin Harrison). ENGLISH SOVEREIGNS. A UNIQUE EXERCISE. The method here used of memorising the order of the English sovereigns from William I., the Conqueror, to Victoria possesses the following novelties:--
