a8g90.] RAFTER AND MALLORY—ENDEMIC OF TYPHOID FEVER. 73 
There were seven gelatine needle cultures made from suspected colonies. On 
November 18, examination of these cultures showed two liquefying, one a sterile 
one, and four suspicious. Microscopical examination of these four showed two to 
be micrococci, and two to be rods. These latter were planted upon sterilized 
potato, and on Nov. 25 showed an abundant growth with color formation along 
the needle track and were therefore rejecied as not being the typhoid bac.llus. 
WaTeER No. 6—(Morris and Grover well.) —The saucer contained numerous 
liquefying and countless non-liquefying colonies. A few cultures were made. 
_ _ Plates 1, 2, 3, all showed numerous liquefying and countless non liquefying 
colonies. A count was impossible and no further culture were made. 
Of three gelatine needle cultures made—all showed under the microscope 
that they were made up of micrococci. 
Water No. 8 —(Snyder hotel well) —Saucers and plates were completely liquefied 
and contained also countless numbers of non-liquefying colonies. No count was 
possible and no cultures were made. 
WaTER No, 9—(Doty well.)—Precisely the same as with No. 8. 
“WaTER No. 11—(Lime Ki!n Gull creek at north end of village.) 
Saucer completely liquefied. 
Plate I. 2000 non-liquefying colonies. 
18 liquefying colonies. 
(A few cultures made.) 
Plate 2. Liquefied. 
Plate 3. About the same as No. 1. 
The pipette used measured twenty-five drops to 1 c. c., and the water contained 
therefore about 1,coo colonies to 1 c. c. There were numerous liquefiying 
-colonies, and there were eight gelatine needle cultures made. Microscopical 
examination of these cultures on Nov. 18, showed that seven of them were made 
up of micrococci and one of rods. The last was planted on sterilized potato and 
on Nov. 25 showed a yellow colony and was therefore rejected. 
“WaTER No. 15—(Hemlock lake, inlet well at lake gate-house.) 
_ Saucer liquefied. 
Plate 1. 50 small liquefying colonies. 
690 non-liquefying colonies. 
Plate 2.—100 liquefying colonies. 
600 non-liquefying colonies. 
Plate 3. About the same as plate 2. 
1 
The pipette used, measured 30 drops to the c. c. and the water therefore contained 
-about 4,000 colonies to I c. c, 
There was a large number of liquefying colonies but not of very rapid growth. 
Nineteen gelatine needle cultures were made. Examinations of these cultures 
showed that there was color formation in two, liquefaction in three, micrococci in 
twelve, and rods in two. These last two were planted upon sterilized potato, and 
on Noy. 26, in one there had appeared an abundant yellowish white growth along 
“the needle track, and im the other an abundant growth with a dark discoloration 
of the surrounding potato. They were both rejected therefore,
