BIBLIOGRAPHY. 
Offal Establishments (Clos d’EquarrissageL Industry, public and professional 
hygiene, sanitary police, legislation. By Dr. A. Morel, Sanitary Veterinarian. I 
vol. 8vo. With plates in the text. Published by Asselin & Houzeau, Paris. 
The author has taken this subject for that of his thesis for 
the degree of M. D. After addressing thanks to the numerous 
professors of the faculty of medicine and of the hospitals at which 
he had followed the different teachings, and paying a respectful 
acknowledgment principally to a few of his masters, in a short 
introduction the author gives the definition of the Clos cPEquar- 
^Hssage and of their importance to the point of view of salubrity 
and of their source of benefits to industry, trade and agriculture, 
alluding also to the great inconvenience that they offer to pub¬ 
lic hygiene and to the dangers run by those who are employed 
in them. The object of the work, says the author, “ has been 
to bring out all that has appeared to us to be a cause of insalu¬ 
brity in that industry and to indicate all the improvements that 
could be made into it.” 
The book is divided into five parts : ist, the industry of 
the knacker ; 2d, establishment to the point of view of public 
hygiene; 3d, to that of professional hygiene; 4th, sanitary 
police ; 5th, legislation. 
To have been able to do justice to the subject, it was neces¬ 
sary for him to know that kind of industry in its most minute 
details, so as to judge-its defective points, objections, dangers; 
it was necessary to follow the work of knackers themselves, know 
of their habits, study their life. The author has seen all that, 
and obtained his documents from close observations in the 
best organized establishments ; he speaks of what he has 
seen and observed, he had all the competency to judge and 
discuss. 
Although the subject may seem at first strange to some 
veterinarians (possibly more so in America), in its relations to 
veterinary science; a more careful consideration of the subject will 
show that in the point of view of hygiene and sanitary science 
it is one which veterinary surgeons as well as physicians cannot 
ignore and the interest that it commands is of itself sufficient 
evidence of the value of the excellent thesis of Dr. Morel. All 
those that can read it will find in it abundance of important in¬ 
formation, beside much sound advice as to the necessitv of 
careful attention in making post-mortems of animals that have 
died of special contagious diseases.
