TRANSLATOR’S PREFACE. 
Being but a layman, and fearing that, by changing terms and 
reconstructing sentences, | might not exactly convey the 
ideas of the author, I simply made a literal translation, and 
left the arduous task of reconstructing all such sentences 
which would possibly impair the sense of any part, to Pro- 
fessors A. H. Baker and L. A. Merillat, who have also written 
many valuable annotations, thus bringing this little work to 
an up-to-date level. To these gentlemen belongs the credit 
of this addition to Veterinary Literature, and I hereby ex- 
press to them my sincere thanks for their labor in arranging 
the matter. 
If my readers, refraining from severe criticism, can obtain 
any useful information from these pages, I will feel fully repaid.
