incomplete knowledge of the haemorrhagic diatheses will not 
at the present time allow us to draw a sharp line of demar¬ 
cation between these two conditions ; each practitioner must 
decide for himself whether the concrete case before him is one 
of morbus maculosus or scurvy. While ulceration and 
haemorrhages into the gums are diagnostic features of scurvy 
in the human subject, yet it must be conceded that they can 
also occur in morbus maculosus. But in general one can assert 
that in human pathology the disease known as scurvy is not 
as serious nor does it run so severe a course as does the latter. 
In general the cause of scurvy can be traced to faulty dietetics 
(absence of vegetable regimen). Close questioning elicited the 
fact that this dog received proper diet, also that there was not 
the least reason to suspect poisoning. Prognosis bad. Four 
days after the dog died of symptoms of profuse haemorrhage, 
the nose bleeding profusely before death. The autopsy showed 
the ordinary haemorrhage present in patients dying of morbus 
maculosus. In the peritoneal cavity 2^ litres of'blood extrava¬ 
sation, in the submucosa of the stomach and intestines haemor¬ 
rhages, in the peritoneal coating of the intestines numerous 
ecchymoses, and in the liver, spleen, and kidneys haemorrhages 
appeared. The liver was markedly, the spleen moderately en¬ 
larged. In the pericardium i ^ litres of blood exudate ap¬ 
peared ; in the heart were haemorrhages into the endocardium 
and insufficiency of the mitral valve. The lungs showed 
numerous bloody infarcts and a marked chronic bronchitis. 
There were no patechial spots or haemorrhages into the skin, 
subcutaneous tissue, muscles or joints. In scurvy of human 
subjects patechiae into the skin and subcutaneous tissue and 
especially extravasations into the joints and epiphyses are very 
common, which two symptoms, especially the joint symptom in 
connection with spongy and bloody-gum, make diagnosis of 
scurvy almost positive.— [My own (Bieser’s) interpolation].—
