188 KANSAS CITY REVIEW OF SCIENCE. 
The malady reached its climax in about twenty four hours. It was first sus- 
suspected that the water supply had been somehow poisoned, but many people 
who had not used the water were prostrated, while others who used it freely escaped. 
Adams has hitherto been regarded as an exceptionally healthy town, and the sur- 
rounding country is high and wholesome.—Sccentzjic American. 
PERSEVERANCE WITH THE DROWNED. 
In a recent communication to the French Academy, Professor Fort asserts 
that he was enabled to restore to life a child three years old, by practicing artifi- 
cial respiration on it four hours, commencing three hours and half after apparent 
death. He mentions also a case in which Dr. Fournol, of Billancourt, reanima- 
ted, in July, 1878, an apparently drowned person by four hours of artificial respi- 
ration begun one hour after the patient was taken from the water. At this season, 
when cases of drowning are apt to be frequent, the possible benefit that may 
come from a persevering effort to revive victims of drowning, should encourage 
friends not to despair of their resuscitation, even after several hours of seemingly 
fruitless labor.— Scientific American. 
SIMPLE TEST FOR CHLORAL HYDRATE. 
A new test for chloral hydrate has been devised by Frank Ogston, namely, 
yellow sulphide of ammonia. On adding this reagent to a solution of chloral of 
moderate strength there is at first no change noticed, but in a short time the color- 
less solution acquires an orange yellow color, and on longer standing turns brown 
and evolves a gas of a very disagreeable odor. Ogston’s experiments show that 
a solution containing ten milligrammes turns brown in six hours, and gives the 
peculiar odor. With one milligramme the orange yellow color appears in twelve 
hours, but no odor. Croton chloral gives the same reaction, but chloroform, 
chloric ether, and formic acid do not.

The origin of the human race, lost as it is in the night of antiquity, is a sub- 
ject of fascinating interest, and has been a theme of speculation from the earliest 
ages of history. When and where did man make his first appearance on earth is 
an oft recurring question. From the wild inhospitable wastes of the Polar re-
