934 
gress at Monaco in 1913: All propositions for 
amendments to rules on nomenclature which are 
approved by a majority of the International Com- 
mission on Nomenclature shall be submitted to the 
International Congress for final decision by vote in 
open meeting. In case it appears that any legis- 
lation to the contrary has been adopted by a pre- 
vious International Congress, the International 
Congress at Monaco is respectfully urged to re- 
consider and repeal such action. 
Signed, S. W. WILLISTON

The treasurer of the society was authorized to 
allow the committee on nomenclature funds suffi- 
cient to obtain a census of opinion regarding the 
question of priority in nomenclature. 
Professors Lillie, Lefevre and Patterson were 
appointed a committee to draw up resolutions upon 
the death of Professor Montgomery. 
The following papers were presented at the 
meeting, either in full or by title:

On the Presence of Independent Mesenchymal 
Lymph Spaces in Turtle Embryos as Deter- 
mined by the Study of Injections and Sections: 
FRANK A. STROMSTEN, University of Iowa. 
The results set forth in this paper were based 
on the study of embryos of the loggerhead turtle. 
The blood-vascular system had been injected 
through the vitelline vessels. The lymphatics were 
injected through the jugular lymph-sacs, using the 
methods of Knower and Sabin. Serial sections of 
these embryos show that the peri-aortic lymph 
plexus is always preceded by a series of inde- 
pendent spaces which can neither be injected from 
the lymphatic nor the blood-vascular systems. 
Proofs, based on a series of photomicrographs and 
wax reconstructions, were given to show that these 
independent spaces are derived directly from the 
original intercellular mesenchymal spaces, and 
that they finally become part and parcel of the 
lymphatic plexus.

The Morphology of the Sympathetic Neurones in 
the Myenteric and Submucous Plexuses: ALBERT 
Kuntz, University of Iowa. 
In the myenteric and the submucous plexus in 
the small intestine of the cat and the dog sym- 
pathetic neurones of several distinct types may be 
observed. The two types which are most evident 
may be characterized as follows: (a) neurones 
which are irregular and more or less angular in 
outline possessing numerous varicose dendrites 
which vary greatly in length and in diameter 
and usually show numerous short branches; (b) 
neurones which are more regular in outline, pos- 
sessing fewer dendrites which are usually long 
and slender and show only few branches. Neu- 
tones of both these types are present in consid- 
erable numbers in the myenteric plexus. In the 
submucous plexus the neurones of the second type 
preponderate. 
The ganglia of these plexuses are variously con- 
nected by commissures in which may be traced 
both axones and dendrites. Fibrous commissures 
also connect the two plexuses with each other, 
while from the submucous plexus fibers may be 
traced into the plexuses surrounding the digestive 
glands and into the intestinal villi, where many of 
them, doubtless, terminate on cells of the digestive 
epithelium. Such terminations could frequently be 
observed, but in no case could an individual fiber 
be traced from its termination on the digestive 
epithelium back to the cell-body from which it 
arose. 
The fibers terminating on the digestive epi- 
thelium, doubtless, subserve a receptive function. 
They are probably the dendrites of neurones of 
the second type above described. These neurones 
would, therefore, be sensory in character. The 
axones of some of the neurones of the first type 
above described terminate directly on smooth 
muscle-fibers. These neurones are obviously motor 
in character. The distribution and the orientation 
of the neurones in these plexuses is obviously such 
as would be required by a system of local reflex 
ares. That such a system of reflex ares is present 
in the walls of the digestive tube has already been 
suggested by Dogiel, Miiller and others. Indeed,
