knighted in 1866, and created Baron Kelvin in 

 1892. 



Kepler, Johann, ii, 70. Born at Weil der Stadt, 

 Wiirtemberg, Dec. 27, 1571; died at Ratisbon, 

 Bavaria, Nov. 15, 1630. One of the founders 

 of modern astronomy. His name is associated 

 with three laws of planetary motion, which are 

 as follows: (i) The orbits of the planets are 

 ellipses having the sun at one focus; (2) The 

 areas described by their radii vectores in equal 

 times are equal; (3) The squares of their peri- 

 odic times are proportional to the cubes of their 

 mean distances from the sun. 



Khamurabi, (Hammurabi), Code of i, 76. 

 King of Babylon about 2000 B.C. He instituted 

 a code of laws older than the laws of either 

 Manu or Moses. 



Kirchhoff, Gustav Robert, iv, 69. Born at 

 Konigsberg, Prussia, Mar. 12, 1824; died at Ber- 

 lin, Oct. 17, 1887. German physicist. With 

 Bunsen he discovered the method of spectrum 

 analysis in 1860. 



Kleist, Dean von. (See Von Kleist.) 



Koch, Dr. Robert, iv, 228. Born at Klansthal, 

 Hanover, Dec. u, 1843; died May 27, 1910. Ger- 

 man bacteriologist. In his study of bacteriol- 

 ogy he isolated the anthrax bacillus, and in 1883 

 announced a method of preventive inoculation 

 against the disease. The year before (1882) he 

 discovered the bacillus of tuberculosis, and eight 

 years later announced the discovery of tubercu- 

 lin, which he hoped would prove to be a cure 

 for consumption. In 1883 he identified the 

 comma bacillus as the organism responsible for 

 Asiatic cholera.
