748 EXTRACTS FROM FOREIGN JOURNALS. 
That these abscesses are occasioned by pressure of the 
collar there can be no doubt; they are indigenous to draught 
horses, and incidental to their occupation. It may be of his¬ 
torical interest to note Hertwig’s earlier description of the 
condition as being induced by inflamed testicles. 
Since the pus always contains cocci, we are justified in 
assuming them to be deposited by the lymphatic system in 
the glands of this locality. Prognosis is favorable, and if of 
ancient formation the course is slow ; small swellings, which 
are scarcely visible, are more tedious than those of larger 
dimensions. In the latter a cure is effected by dispersion, but 
in the former the ultima ratio consists in operative removal. 
In many text books cataplasms and salves are recommended; 
we admit the possibility of removal through these medicines, 
but have ourselves never achieved the desired end by them. 
By these agents we have succeeded in softening the enlarge¬ 
ment and increasing the suppurative process in eight to ten 
days; in other cases, however, warm fomentations, salves 
and parenchymatous injections, when continually applied 
through weeks and months, have yielded no good. From our 
experience we have abandoned the above methods, and now 
resort to the bistoury. 
The swelling, irrespective of consistence or circumference, 
is incised. Cases are sometimes met in which this procedure 
fails ; in such cases extirpation offers the only means of ulti¬ 
mate eradication. Dr. Schmidt has recently recommended 
the injection of a concentrated sod. chloride solution. From 
this treatment the abscess becomes exceedingly painful and 
suppurates. Many colleagues in our association have applied 
the Schmidt treatment with good results, though we cannot 
report the same satisfactory end. Schmidt himself admits 
that in old cases the result is uncertain. Extermination is per se 
not very difficult, but from the dangerous proximity of the 
carotid and jugular a degree ol skill and care are demanded. 
We were much surprised to read that Stockfleth recommend¬ 
ed the performance upon animals in the standing position. 
As in all considerable operation we first chloroform the 
patient—by this opportunity apropos allow me to say that
