World's Fair. Mr. Bancroft went south, says The Publisher's 

 Weekly, to avoid rather than to seek work. Having many warm 

 friends in that quarter, he had hoped for a brief jieriod of rest 

 after many years of seveie labor. But when Gen. Diaz made this 

 request, offering at the same time not only to co-operate with him 

 in every respect, to give him freely his own views on all important 

 subjects, but to enlist the co-operation of the chiefs of depart- 

 ments and Governors of States, he felt that he could not refuse. 

 Gen. Diaz had shown him many favors in times past; further- 

 more, the subject had peculiar attractions. He had been over the 

 same ground historically, and was interested in its later develop- 

 ment. As in all his publications, Mr. Bancroft will utilize the 

 labors of able assistants, who have been at work in various parts 

 of the republic collecting material. Besides these, Mr. George H. 

 Morrison, Secretary of the History Company of San Francisco, 

 will at once join Mr. Bancroft in Mexico, and assist in carrying 

 forward this important undertaking. 



— The geographical collection made by the Department of 

 Geography of the Brooklyn Institute during the years 1889 and 

 1890, and very greatly increased in value and completeness, will 

 be exhibited in the Natural History Building in Central Park, New 

 York, at Fifth Avenue and Sixty-fourth Street, for six weeks, be- 

 ginning on Dec. 24, at nine o'clock. The exhibilion will occupy 

 the two main floors of the building; and will be open free to the 

 public from 9 a.m. to 6 p.m., on six days in the week, and until 

 ten o'clock on Wednesday and Saturday evenings. The exhibition 

 is given at this time in order to afford teachers, superintendents, 

 and all others interested in education from all parts of the country, 

 to visit and study the collection during the holidays, when the 

 schools are not in session. The exhibition is made undf r the aus- 

 pices of the New York Teachers' Association, which defrays all 

 the incidental expenses. The Board of Park Commissioners of 

 New York have generously contributed the use of the Museum 

 Building.

A most excellent and agree- 

 able tonic and appetizer. It 

 nourishes and invigorates the 

 tired brain and body, imparts re- 

 newed energy and vitality, and 

 enlivens the functions. 



Dr. Ephbaim Bateman, Cedarville, N. J., 

 says: 



' ' I have used it for several years, not only 

 in my practice, but in my own individual 

 case, and consider it under all circumstances 

 one of the best nerve tonics that we possess. 

 For mental exhaustion or overwork it gives 

 renewed strength and vigor to the entire 

 system . ' '
