"globular" theory, due less to speculation than er- 

 roneous methods of observation and imperfect in- 

 struments. Leeuwenhoek* (1687) early announced 

 the "globular" structure of the primitive tissues 

 of the body, but the "globule" apparently attracted 

 little notice until this period of reaction against the 

 " fibre," when it claimed the attention of Prochaskaf 

 (1779), FontanaJ (1787), the brothers Wenzel (1812), 

 Treviranusll (1816), Bauer^[ (1818 and 1823), Heu-
