WE learn from the London Times that the 
Department of Agriculture and Technical In- 
struction for Ireland has, with the concurrence 
of the Agricultural Board and the Board of 
Technical Instruction, allocated a sum of £5,000 
to the purposes of the Cork Exhibition, 1902, 
to be applied on condition that the general 
scheme of the exhibition is approved by the de- 
partment. A portion of this sum will be de- 
voted to the organization by the department of

being introduced into Ireland, or, where al- 
ready established, of being developed on the

THE New York Evening Post states that the 
Mexican government has refused to allow a 
collection of antiquities gathered there by Mar- 
shall H. Saville, assistant curator of the Amer- 
ican Museum of Natural History, to be shipped 
out of the country. Mr. Saville returned about 
six weeks ago from a six months’ trip in Mexico, 
and will go back to that country in September, 
when he expects to have the dispute adjusted. 
The Mexican law forbids the export of antiq- 
uities, but the Museum has a contract with 
that government by which it is empowered to 
take duplicates of specimens. 
THE government has decided to exclude im- 
migrants suffering from tuberculosis.
