The subject of Typhoid'Never and the Serum Reaction
so intimately associated with it has always been faseinating and interesting. It is still more so when one
realises that the so called Serum Reaction in Typhoid
Never is very occasionally wrong, being sometimes absent in Typhoid Never and more often, though still
seldom, present in other diseases.
To investigate this subject has been my desire and
my chief object in working with the Serum Reaction was
to find out if this trace of error was constant or if
in all cases of Typhoid Never the Serum gave the Aggliininative Reaction, and so to prove the value of the
test. The observations were carried out amongst four
classes of patients and included 255 cases with 855
1st Those suffering from or who had suffered from Nnteric Never;
2nd Those suffering from diseases resembling Enteric,
but in whom the Diagnosis clinically was uncertain.
3rd Those suffering from or convalescent from other diseases belonging mainly to the infective group.
4th Normal healthy people.
The results of my observations are given in Tables
situated at the end of the Volume. Those.relating
to the group of various diseases have "been typed, whilst
for the sake of ease in examination the tabular results belonging to the Enteric group have been drawn
out by hand.
