loiiij, tul)ular cells loosely and sinuously disposed would lie. so 
that there were longitudinal and transverse, as well as obliciue 
sections of them. Lonoitudinally they show an apparent cell wall 
and prominent central cavity. They are more or less vermicular 
and simple or irregularly branching. The cavity is often filled 
with a poorly defined granular substance, and they sometimes 
contain air. 
\\\ transverse section the apparent wall appears prominently, 
and shows as what seems to be a rather thick wall with an onter 
and dark, limiting membrane. The tubes are usually about H9 
//. broad, and the wall 14 ," thick. 
The small myceloid nimuli are freely branching and some- 
what interlacing, and in many cases are filled with air. It is 
very common to find them occupying large areas of the rods, 
while less frequently they assume the form of stellate groups 
closely resemblings tufts of Rindaria. These groups are com- 
monly 109 , a broad The separate tubes measure from 1.9//. to- 
3.8 ,'/. and even 15 /- in diameter. In the smaller forms where 
the radial disposition is most pronounced, these ranudi com- 
monly terminate in sub-s})herical pockets. 
The substance lying I)ctween and apparently cementing the 
rods together, consists chiefly of a fine granular matter — the 
granules Ijeing very angular — which seems to have been derived 
from the same material as the rods through some pulverizing 
action. 
Section 1 was prepared at the lledpath Museum, as were all 
the following sections. In this the rods show frequent round: 
air cavities measuring from 9. (i // to 105.0 // in diameter. Small 
laminae and angular fragments fill the spaces between the rods,, 
apparently consisting of tlu; sanu' material. The rods themselves, 
are wholly structureless and otherwise as in the preceding sec- 
tion. 
Tn section 2 the rods are cut longitudinally and transversely. 
Lines of flow and evidence of structure wholly wanting. The 
fine, myceloid ramuli are abundant and often contain largt- (pian- 
tities of air. The large ramuli are not very abundant, l»ut when 
present usually contain air. The interstitial substance forms a 
spongj' cement — Ixung traversed l»y numerous round openings — 
consisting of minute, angular fragments of aml)er-liki' material
