5th.—That sometimes the price of meat went lip immedi¬ 
ately after the opening of the slaughter-house, or that the 
butchers tried to increase the price, but very soon, as a result of 
competition, the price returned to its former level. 
6th.—That in cities with public slaughter-houses and obliga¬ 
tory inspection the price of meat was not higher than in neigh¬ 
boring cities without these institutions. 
7th.—That the freedom of occupation was increased rather 
than diminished after municipal slaughter-houses were erected, 
because every one who fulfilled the public requirements had the 
privilege to use the establishment. (Previously meat producing 
animals could be slaughtered only by those who possessed the 
necessary premises and appliances.) 
This extensive investigation has shown what economists 
would expect, but what there has been a great tendency to 
doubt. It has shown that, by the species of co-operation that 
must be practiced where large, fully equipped and conveniently 
arranged municipal slaughter-houses are provided, meat can be 
prepared at a lower cost than where it is prepared in a multitude 
of small slaughter-houses. 
EPIZOOTIC ABORTION IN COWS -TREATMENT. 
By Prof. Lignieres, France. 
If several pregnant female guinea-pigs, four or five weeks in 
that condition, are inoculated under the skin with 1 or ]/ 2 c.c. of 
culture of the bacillus, they regularly abort two or five days 
after the inoculation, except if the day after the operation injec¬ 
tions of 1 c.c. of an oily solution of turpinol to one-tenth are 
made; then most of the treated animals do not abort. 
These results have decided me to try this treatment on cows ; 
and I was fortunate enough to obtain the assistance of a veteri¬ 
narian who carried out the experiments under my direction. 
First Experiment .—Stable of Mr. F. : Abortion began in 
August, 1896 ; 7 out of 10 cows had aborted. In 1897 the disease 
returns, but injections of turpinol are started the end of October of
