146 SIDNEY F. HARMER. 
stead, of Christ’s College, Cambridge, for having made and 
communicated to me, after my departure from Naples, some 
further observations on the history of the experiment which I 
had commenced. 
The following statements, referring to F. papyrea, are 
given on the authority of Mr. Newstead, to whom I express 
here my very best thanks. 
At the 622nd hour the disintegration of the “ brown body ” 
had already progressed some distance, and dark masses derived 
from it were observed in the rectum. 
In the following days the disintegration of the “ brown 
body” continued, fragments being broken off from it and 
passing into the lumen of the alimentary canal. The frag- 
mentation of the “ brown bodies” was taking place actively at 
about the 743rd hour; in some of the individuals the greater 
part of the “brown body” was by this time accumulated in 
the rectum. : 
At the 959th hour the rectum had, in some cases, emptied 
itself, although a small portion of the ‘‘ brown body ”’ was still 
left at the apex of the cecum (as in Haddon’s pl. xxxvii, 
fig. 11). 
During the process of fragmentation of the “ brown body,” 
Mr. Newstead was able to observe most conclusively that the 
indigo-carmine which was contained in the “brown body ” 
passed into the cavity of the new alimentary canal, where it 
was seen as distinct blue masses in the intestine, rectum, &c. 
This is especially alluded to in Mr. Newstead’s notes referring 
to the 790th—808th hours. 
At the 880th hour these blue fragments had entirely disap- 
peared in some of the individuals, and there can be no doubt 
that they had left the alimentary canal, with other parts of 
the “ brown body,” by a process of defecation. 
In other cases blue fragments were still observed in the 
intestine and rectum as late as the 1744th hour, the last 
observation recorded. 
During the fragmentation of the ‘ brown bodies” which 
contained indigo-carmine, Mr. Newstead was unable to ob-
