FROM THE PREFACE 
The work has been largely prepared since the outbreak of 
the present war and, for this reason, is not as exhaustive as I 
had originally intended it to be, as owing to official duties it 
has been impossible to spend as much time in its preparation 
as would have been necessary to make it an exhaustive treatise, 
and it has also been impossible for me to consult much of the 
very extensive literature that has accumulated during recent 
years in regard to the test. However, it is believed that the 
work contains all of the essential and really valuable facts re- 
garding the test which have been reported in the literature, and 
if there have been any omissions I would deem it a favor to have 
them called to my attention. 
I have quoted quite liberally from some of the more recent 
investigators, as Noguchi, Nichols, Vedder, and Kolmer, and have 
also used much data previously published by myself in various 
medical journals, and it is a pleasure to tender my thanks to the 
editors of the Journal of the American Medical Association, the 
Journal of Experimental Medicine, the Journal of Infectious 
Diseases, and the American Journal of Syphilis, for permission 
to avail myself of the data previously published in these journals. 
From personal experience, I believe that there is still a great 
deal of misunderstanding and confusion among the members of 
the medical profession regarding the exact value and limitations 
of the Wassermann test, both in the diagnosis of syphilis, and 
when used as a control of the treatment of the disease, and if 
this work will help in clearing up this confusion it will be a 
Source of great gratification. Much of this misunderstanding 
rests upon the shoulders of laboratory workers, for it must be 
admitted that too often the performance of the Wassermann 
test has been delegated to poorly trained or careless assistants, 
and the results obtained with the test have thus been erroneous 
and unsatisfactory. I can not urge too strongly upon the profes-
