(a.) Zenker reports a case where twenty-three swine were 
infected with trichinae from consuming the drainage of a sink 
from a castle. 
9th. Feeding the offal of slaughtered swine to other swine, 
cooked or uncooked, or having slaughter houses over places where 
swine are kept, should be forbidden by law. 
10th. Competently educated veterinary inspectors should be 
appointed by the State Board of Health of eacli State, after 
having first passed a special examination in the principles of pre- 
ventive medicine, to see that these various regulations (and others 
with reference to other as well as contagio-infectious diseases of 
animals) are strictly attended to. 
Public feeling should be excited in this matter, and pork 
raisers led to feel it to be their duty to have their hogs examined 
before cutting them up for market. In fact, another regulation 
should be added to the above, viz.: 
That no slaughtered hog should be allowed to be cut up until 
its flesh has been microscopically examined by one of the above 
named inspectors, and a suitable State brand of “ Inspected for 
Trichinae,” burnt upon the hams, shoulders, sides and cheeks. 
THE MICROSCOPIC EXAMINATION OF PORK. 
Numerous elaborate essays have been written upon this sub¬ 
ject, but the entire process is so easy and simple that such ex¬ 
tended labor may well be looked upon as useless. 
Almost the first, and, at the same time, by far the most pro¬ 
fusely infested muscular system, is the so-called “pillars of the 
diaphragm .” These are to be always found as two small stumps 
of flesh situated immediately below the kidneys in the dressed 
hog when hung up to u cool out.” If there is a single trichina 
in the organism it is to be found here. These portions belong to 
the trimmings, and are always to bo had without in airy manner 
disturbing the appearance of the hog. 
Although a power of 15 to 20 diameters is sufficient to de¬ 
monstrate the parasites to the proficient observer, it is still much 
better to use a power of 50 to 75 diameters. 
Good microscopes for such a purpose are to be had from 
.American makers for front fifteen tQ twenty dollars, If the
