OKLAHOMA ACADEMY OF SCIENCE 23 



At the dedication in 1888 of the Pasteur Institute, which was 

 bui't by public subscription, Pasteur said : "Alas, it is my most 

 poignant sorrow that I enter it as a man already vanquished with 

 age, no longer surrounded by my masters" — to his collabrators he 

 said ; "Hold fast to the enthusiasm — which has been yours since 

 the earliest hour,— assert nothing that cannot be proved in some 

 simple and decisive fashion." 



In concluding his dedicatory address he said : "Two adverse 

 laws seem to me now in conflict. One law of blood and death, 

 opening out each day new modes of destruction, forces nations to 

 be always ready for the battle-field. The other a law of peace, of 

 work, of safety, whose only stud}^ is to deliver man from the 

 calamities which beset him. 



The one seeks only violent conquests. The other only the re- 

 lief of humanity. The one places a single life above all victories. 

 The other sacrifices the lives of hundreds of thousands to the 

 ambition of a single individual. The laAV of which we are the 

 instruments, strives even through the carnage to cure the bloody 

 wounds caused by the law of war. Treatment by our antiseptic 

 methods may preserve thousands of soldiers. 



Which of these two laws will prevail over the other? God 

 only knows. But of this we may be sure, that science in obeying 

 this law of humanity will always labor to enlarge the frontiers 

 of life."

The contributions of Mendel to biological science have been 

 recognized so generally during the last two decades that in many 

 parts of the world during the past year scientific men have joined 

 in celebration of the centennial of his birth. Bateson, one of the 

 foremost students of heredity of the present day has made an 

 extensive study of the life of Mendel and the events connected 

 therewith. From his account*, many of the facts in the present 



During the period from 1853 to 1868, Mendel was a teacher 

 especially of physics in the Realschuie at Bruenn, and during a 

 certain part of this period he carried on experiments in the large 

 garden of the cloister there. This institution which was the Aug-
