■with the disintegration of the epithelial structures, forms this viscid 
substance, is uncertain. 
To finish the summary of the various parts belonging to the 
papilla and its muscular support, it is necessary to allude further 
to the distribution of nerves to voluntary or striped muscle given in 
Kg. 9. 
Eepeated controversies have occurred between various observers : 
some contending that the nerve is attached by a terminal plate to 
the sarcolemma ; some, that its fibres pierce the same and are con- 
tinuous with the sarcode elements ; others, that a plexus is formed 
outside the primitive fibres on the sarcolemma, and has no terminal 
parts beyond this minute plexiform arrangement. We cannot expect 
each to be right unless we can find two or three distinct modes by 
which the muscular fibres are supplied with nerves. The arrange- 
ment figured, is that which I have met with in the muscles of the 
tongue of the frog; where the dark-bordered nerve-fibres, after 
forming a pretty close plexiform network, are applied to the edges 
between two muscles, and attached to the sarcolemma of the muscular 
fibre by the intervention of large nuclear masses ; forming what, I 
believe, is called the nerve-tuft plate, or bud, which do not appear 
as nuclear masses of the muscle, but belong to the nerves themselves ; 
as Dr. Beale remarked they can be stripped from the sarcolemma, 
as seen in the Figures here given. They are well shown in the 
Plate ; but on careful examination of those specimens which permit 
of the displacement of the adjoining connective tissue, so as to 
separate the muscular bundles, delicate nerve-fibres can be traced 
from the intervening space, forming a close plexus, distributed in 
fine granular threads over the surface of the sarcolemma of the 
adjoining muscles, and continuous with the germinal masses and 
the tufts which dipped down between the proximate bundles. Some 
of the fibres, a h, which have no nucleated plate on the edge, often 
adhere closely to the sarcolemma, and raise or pucker it when 
dragged ; such fibres furnish minute branches which unite between 
themselves, and also with the plexiform fibres connected with the 
masses of nuclear or germinal matter at the edge of the muscle ; 
whilst from one end, in the direction of the length of the muscular 
fibre, or from the last nuclear mass, a very fine nerve-fibre can be 
traced for some distance (Fig. 9 e c). 
It will be easy to see how such a structure as that figured might 
misguide the observer. If by the employment of unsuitable media 
we could not see the connecting fibres of the plexus on the sarco- 
lemma, we should have the nerve-tufts " nerven-hiigel ; " if only 
the fine fibres which are stretched, we should have appearances 
that would lead to the supposition of the nerve-fibre penetrating 
the sarcolemma and distributed within or uniting with the sarcode 
substance ; and if we saw only the fine plexus distributed over the
