434 Scientific Intelligence. 
he was always an indefatigable worker will be apparent from 
what has been said of the work which he accomplished, but it 
would be made more apparent by an enumeration of the long list 
of his writings. The untimely ending of a career so full of active, 
useful work, is a great loss to science and his country. We close 
this notice with another. quotation from the same source, which is 
interesting as giving an insight into one side of his character: 
‘One other trait which we have not mentioned is his persistency 
in overcoming obstacles. Nothing daunts him, and the more 
difficult an end is to attain, so much the more energy and perse- 
verance does he put forth in its pursuit. A recent instance of 
this quality we may cite: The Fluted Scale (dcerya Purchasi 
Maskill) has done great injury to citrus fruit in Southern Califor- 
nia of late years. Ascertaining that it is kept in check by nat- 
ural enemies in its native home, Australia, Dr. Riley foresaw 
the importance of endeavoring to introduce these enemies. Not 
only did Congress refuse to appropriate money for the purpose, 
but it refused to do away with a clause in the appropriation bill 
restricting all expenditures to the United States. 1n this state 
of affairs most men would have given up the fight; but Dr. Riley, 
after great trouble, succeeded in accomplishing his end by induc- 
ing the Secretary of State to allow the sending of two assistants 
on the Melbourne Exposition Commission, and through their labors 
the desired result was reached. Hundreds of specimens of an 
Australian lady-bird ( Vedalia cardinalis) were introduced into 
California, and the dreaded pest is now being speedily reduced to 
absolute harmlessness. Professor W. A. Henry of Wisconsin, in 
a recently published article, says of this matter, in speaking of the 
enthusiasm of the people of California over the result of this impor- 
tation: ‘Without doubt it is the best stroke ever made by the 
Agricultural Department at Washington.’ ” 
M. Lovis Pasteur, whose researches in chemistry and bac- 
teriology have proved of such incalculable benefit to human- 
ity, died on September 28, at the age of sixty-three. It may be 
questioned whether it has ever been the privilege of any other 
scientist to accomplish so much for the welfare of his fellow men 
and the alleviation of their sufferings, as he did through his own 
labors and those which he inspired. 
Ext Wuitnrey Brake, Professor of Physics in Brown Uni- 
versity, died on October Ist, at the age of fifty-nine. 
Dr. ALBERT E. Footr, the indefatigable mineral collector, 
whose active labors through many years have contributed largely 
to the development of a widespread interest in mineralogy through- 
out the country, died at Atlanta, Georgia, on the 10th of October, 
in his 49th year. He had suffered long from ill health, but not- 
withstanding -physical disability he carried on his work with 
unceasing energy and enterprise up to the very last.
