spared to us, whose work on striped muscle in 1849 added much to 

 our knowledge of this subject we still use the term " Dobie's line "- 

 and that of G. B. AMICI (1784-1863). Amici gives an excellent 

 figure of the structure of striated muscle (Virchow's Archie, XVI., 

 1859), but he used the muscles of insects as a test-object for his 

 microscopes. His name is associated with the " stria of Amici," 

 with immersion lenses, and, along with that of Mr. Lister, with 

 achromatic lenses. 



Closely linked with muscular contraction are the movements 

 of protoplasm, animal and vegetable. We recall the work of 

 Dujardin. H. von Mohl, Wharton Jones, M. Schultze, &c. I have 

 associated the portraits of Amici and Corti. Both belong to the 

 school of Modena. W. Kiihne, in one of his latest papers, Die

 Unters. iilier d. Protoplasma, was published in 1864. 



BONAVENTURA CORTI stated that the motion in the cells of 

 Chara is brought to a standstill by the withdrawal of oxygen. 

 The Chara was submerged in oil. Corti discovered rotation 

 in the cells of Chara, and it was assumed that the above-cited 

 experiment showed its dependence on the presence of oxygen. It 

 is obvious that, considering the presence of chlorophyll, the latter
