1 The late Professor Max Schultze, in his article in the first number of his ' Archiv 

 fur Mikroskopische Anatomie' (1865), whilst observing that *lm Blute ist gewiss kein 

 Bestandtheil gleichgultig ' (p. 36), and discussing the import of the ' Zimmermannsche 

 Korperchen,' adds that they have been left unmentioned in the recent handbooks of 

 microscopic anatomy. It may be worth while, therefore, to supply here certain 

 references to memoirs which treat of them, and bodies closely allied to them, and 

 which, with the exception of those by Zimmermann himself, mostly point to their 

 being properly regarded either as arte/acta, or as morbid, or as post-mortem 

 products : —

 of as ' Trummer und Bruchstiicke alter Blutkorperchen.' 



Schultze (I.e. 1865, pp. 38-41) recommends further investigation into the nature 

 of the several ' Kornchenbildungen' in blood, not considering them to be all alike 

 either arte/acta or what Mr. Gulliver has called the ' molecular basis of the chyle.'

The 'minute spherules' described by Mr. Gulliver (' Gerber's General Anatomy,' 

 pp. 10, 23, 24, 25, Appendix, and fig. 268) appear to be identical with the ' Zimmer- 

 mannsche Korperchen,' and from his account of them, as also from that given by 

 Martin Barry of the blood, figured by him (' Phil. Trans.' 1. c), we may gather that 

 they are produced in special abundance in altered or altering blood.
