known young farmer near Elgin. It is also reported that Mrs. 
Lorrensen exhibits indications of the disease. Lorrensen was 
twenty-five years of age. The couple was married only last 
spring. The deceased contracted the malady from a horse, and 
had been ill but four weeks, and he suffered indescribable torture. 
Physicians were unable to determine the disease. Finally, a lo¬ 
cal veterinary surmised that the ailment was glanders, and Dr. 
Paaren, of Chicago, who examined into the matter, so decided. 
At Dr. Paaren’s suggestion Lorrensen’s sick horse, that had been 
suffering with an unknown ailment for two years past, was shot. 
Fears are entertained that the disease will spread, although all 
precautions are being taken to prevent it.— Prairie Farmer. 
0 Danger from Flies. —Dr. Grassi is said ( British Medical 
Journal) to have made an important, and by no means pleasant, 
discovery in regard to flies. It was always recognized that these 
insects might carry the germs of infection on their wings or feet, 
but it was not known that they are capable of taking in at the 
mouth such objects as the ova of various worms, and of discharg¬ 
ing them, again unchanged in their fasces. This point has now 
been established, and several striking experiments illustrate it. 
Dr. Grassi exposed in his laboratory a plate containing a great 
number of eggs of a human parasite, the tricocephalus dispar. 
Some sheets of white paper were placed in the kitchen, which 
stands about ten meters from the laboratory. After some hours, 
the usual little spots produced by the faeces of flies were found on 
the paper. These spots, when examined by the microscope, were 
found to contain some of the eggs of the tricocephalus. Some of 
the flies themselves were then caught, and their intestines pre¬ 
sented large numbers of the ova. Similar experiments with the 
ova of the oxyuris vermicularis and of the tcenia solium afforded 
corresponding results. Shortly after the flies had some mouldy 
cream, the oidium lactis was found in their faeces. Dr. Grassi 
inetions an innocuous and yet conclusive experiment that every 
one can try. Sprinkle a little lycopodium on sweetened water, 
and afterward examine the faeces and intestines of the flies ; nu¬ 
merous spores will be found. As flies are by no means particu-
