 an experiment, in which 5 cc of a suspension of cells with serum, 

 of cells with heated serum, and of serum alone, were kept at

The anti-enzymotic power exhibited by the serum of the in- 

 flammatory exudate is possessed by the serum of the blood, from 

 which it doubtless passes into the exudate. In the later stages of 

 inflammation produced by aleuronat, and in exudates caused by 

 bacteria, there is some diminution of the anti-enzymotic action. 



43 (89). " Shallow well-waters of Brooklyn " : JAMES P. 

 Atkinson. 



Many streets of Brooklyn are without a public water-supply 

 and a sewage system. The residents of these streets are therefore 

 dependent upon wells for their water-supply, and upon privy vaults 

 and cesspools to remove the sewage and waste water of their 

 homes. The soil is uniformly sandy and water may be had by 

 driving a pipe or digging a few feet below the surface. The water 

 obtained is to a certain extent surface water. The underground 

 water is necessarily influenced by the sea water. This influence is 

 very marked in some instances, as is shown by the high chlorin 

 content, accompanied by the low contents of other constituents 

 that could indicate sewage contamination. 



The following tables present average analytic data regarding 

 condemned shallow wells, also regarding wells considered to be 

 of a suspicious quality and wells which were passed as being of 

 fair quality. Very few of the latter class w r ere considered to be of 

 good quality, and some might possibly have been classed as suspi- 

 cious upon their high nitrate contents, considered with the prox- 

 imity of the sources of contamination.
