bered for his experiments on the physiology of 

 the nerves. 



Malpighi, Marcello, ii, 179. Born near Bo- 

 logna, Italy, March 10, 1628; died at Rome, 

 Nov. 29, 1694. An Italian anatomist and physi- 

 ologist. He is remembered as the father of 

 microscopic anatomy. As early as the year 1661 

 he discovered the capillary vessels connecting 

 the veins and arteries by the aid of the micro- 

 scope. A little later he observed the passage of 

 the blood corpuscles through these minute ves- 

 sels, making his observations on the lung of a 

 turtle. His work completed the last link of the 

 chain which Harvey had all but established in 

 proving the course of the circulation of the 

 blood. 



Marchettis, Peter, ii, 185. (1589-1675.) An 

 Italian physician, one of the leading surgeons 

 of the Seventeenth Century. 



Marconi, Guglielmo, viii, 14. Born at Bo- 

 logna, Italy, April 25, 1874. Italian inventor. 

 Noted for perfecting a system of wireless teleg- 

 raphy. In 1899 he began sending messages 

 across the English Channel, and this date may 

 be considered as opening the era of wireless 

 telegraphy. 



Mariotte, Edme, ii, 210. Born at Burgundy 

 about 1620; died at Paris, May 12, 1684. French 

 physicist. He demonstrated that but for the 

 resistance of the atmosphere, all bodies, whether 

 light or heavy, dense or thin, would fall with 

 equal rapidity. He proved this by the well- 

 known "Guinea-and-feather" experiment pla- 

 cing a coin and a feather in a tube from which 

 the air had been exhausted, and showing that
