dietetic importance is a full supply of pure fresh air, cleanliness 
and a stable temperature of 10—12° C. 
Inoculations in the clew-lap must be absolutely forbidden, as 
the loss from the same has been found to rise to from 5— 8%. By 
exact following of the conditions which we have above discussed, 
the losses from inoculation should scarcely reach 2%, and this 
small percentage should be still more reduced by a trustworthy 
preparation, and preservation methodic in reference to the lymph. 
In reference to the inoculations-metliodic, the lymph may be in¬ 
troduced by means of a lancette, or a bistoury, which, however, 
requires care and practice; much more suitable, however, is the 
inoculation-needle of Strieker, when one has a number of animals 
to operate upon. (A cub-cent. hypodermic syringe is the best 
instrument of all, not only as regards convenience, but cleanliness; 
the instrument here recommended (Strieker’s) is in my opinion 
quite the contrary to what the worthy author says of it, at least 
some experience in inoculatory experiments of this and other kinds, 
where we are not limited to the smallest possible amount of 
material, leads me to recommend the syringe as the best and most 
convenient method—-B.) 
In regard to the “ Impf-technik ” (inoculation methodic) we 
find some very appropriate remarks by Bobouam in BTo. 7, u de 
Archives Veterinaires ” 1878 : 
“ The inoculation by pleuro-pneumonia erysipelatodes is a 
most excellent regulation, when the lymph has been properly 
gathered and prepared, and the action of the inoculation is care¬ 
fully watched for 28 to 30 days, especially in summer.” 
B. slaughters an animal complicated with this disease and 
takes the fiuid from a freshly infiltrated portion of the lung, or 
some parts in the first stages of hepatization; he cuts the parts in 
question in different directions, and presses the same carefully out 
over a suitable vessel; in cooling, the fluid coagulates and is again 
pressed 'through linen, the lymph produced being carefully 
enclosed and set away when not destined for immediate use. 
Lymph taken from the dark colored portions of the lungs gives 
occasion to gangrene much more frequently than that which is 
taken in the above manner.
