The number of leucocytes in the various cases in this series 

 was as follows :

Of twenty differential counts made, there was a decrease to 

 59.8 per cent of the polymorphonuclears, while in about 50 per 

 cent of these cases the lymphocytes exceeded 30 per cent. 

 Large mononuclears were 3.7; transitionals, 4 per cent; and 

 eosinophiles, 1.65 per cent. The haemoglobin estimation had an 

 average of 84 per cent by the Tallqvist method. 



Serum reactions were made 247 times, the dilutions being 

 1-40, the time one hour. Olser considers this an almost specific 

 diagnostic method for typhoid; certainly for routine methods 

 it serves the purpose. During the fiscal year 1912, laboratory 

 facilities were limited and frequently only one reaction was 

 obtained. During that year 37 out of 47, or 78.72 per cent 

 of the suspected cases, gave a positive reaction. During the 

 fiscal year 1913, the agglutination test was made more frequently 

 and several tests were often made on the same patient, par- 

 ticularly when a negative report was received with suggestive 

 clinical findings.
