for a long time as food must always cause miliary tubercles 
and tuberculous degeneration, but it must be admitted that 
the danger of transmission is not so great as might be 
thought ; if it were otherwise, this disease would be more 
frequent in pigs. In these animals it is very exceptional, 
though they are often given the milk of phthisical cows. 
With regard to the danger of transmission of tuberculosis 
of the ox to man we know nothing positive, but we cannot 
absolutely deny it. In 1846 Dr. Klenke described many 
cases in which children became affected with scrofula after 
having been fed with milk from tuberculous cows. Experi¬ 
ments made at the Veterinary School of Dresden, in the 
same direction as those of Bollinger, failed without exception. 
Dr. Willems , of Hassalt, in a letter to M. Bouley, dated 
23rd April, 1880, states that he has succeeded in cultivating 
the special corpuscles which he mentioned in his memoire on 
Pleuro-pneumonia epizootica (1852.) This he has done 
by Pasteur’s method to the eighth generation. They were 
especially lively in an extract of beef. He says, “ I am going 
now to inoculate horned beasts with this product of culti¬ 
vation and to submit others to the influence of the liquid 
vaporised to lead to its introduction through the natural 
channels ”

In continuation of the Papilionacece we now direct atten¬ 
tion to the three following genera, namely : 
1 . Trigonella . Herbs, with curved, many-seeded pods. 
2. Melilotus . Herbs, with straight, one- or few-seeded 
pods. 
3. Medicago . Trifoliate herbs, with pods more or less 
curved or spirally coiled. 
1. The Trigonella is better known to the horse- or cow- 
leech than to the educated veterinarian practitioner. Its 
seeds, which have a smell not unlike that of the pig, from 
which the herb has got the name of u Old Sow,” have some¬ 
what of the aromatic flavour of the Cottmarine. They are 
much used in the various nostrums of horse-doctors and 
grooms, and lately it has come much in vogue as part of
