DISTRIBUTION, OCCURRENCE AND APPEARANCE 
7 
From the latter glands they are indistinguishable in the fresh state, as 
pointed out by Drummond [5] and as previously reported by the writer. 
They never were found on the diaphragm as reported by Warthin [34], 
on the parietes, or in the sub-scapular, axillary or inguinal regions as 
reported by Meek [17] in pathological conditions in man, and but seldom 
and only in very small numbers in the omentum and in the mesentery. 
The latter fact is in marked contrast to the occurrence of supernumerary 
spleens in the cat (Felis domestica) and dog (Canis familiaris) as re- 
ported elsewhere.* Those found in the thoracic cavity, in the cervical 
region, and especially in the intercostal spaces, were smaller, more 
spherical, and less prominent than those in the lumbar region. More- 
over, large specimens were seldom found in any of these regions, the 
grouping was less distinct, and their presence less constant. The occa- 
sional intercostal hemolymph nodes not infrequently simulated small sub- 
pleural hemorrhages so closely that they could not be distinguished from 
them in the fresh state, by inspection alone, and they were too small and 
too flat for puncture injections. 
In the cervical region their occurrence is far less constant than 
in the abdominal and thoracic regions; but they may lie anywhere be- 
tween the thorax and the base of the skull. Usually one or even several 
nodes can be found, however, near the bifurcation of the carotid 
arteries ; and it is not improbable that they have been mistaken for and 
described as para-thyroid glands. In this and in other regions they often 
lie so close to the blood vessels that Weidenreich's [37] conclusion that 
they never lie in direct contact with, even if in close proximity to them, 
is not confirmed; nor can I confirm v Schumacher's observations that 
they usually lie near large lymph vessels, except in so far as large lymph 
vessels are present in the lumbar region. It should be added, however, 
that identification of these small cervical nodes was not always made by 
means of injections, but by microscopic examination and from gross ap- 
pearances. Since, contrary to the statement of White [39], the latter 
means of identification is not wholly reliable, the above conclusions are 
open to question as far as the occurrence of nodes in the cervical region 
is concerned. 
No correlation between the size and the number of hemolymph 
nodes in one region with those in another region, or with the size, num- 
ber and condition of the lymphatic nodes, or with any other condition, 
could be established. Neither were they found enlarged in cases of pneu- 
monia, deep jaundice, tuberculosis, or severe infections with Oesophag-
