128 Germ of the Southern Cattle Plague. 
This concludes my present observations upon the development of 
these etiological organisms in and on different cultivating media. 
Not having a refrigerator, I have not compared their developments. 
upon blood serum up to the present time. 
Now these facts of some of the biological (or life) characteristics 
of these two germs show that, while two germs may look alike and 
grow alike, even in every particular, they may have one other 
attribute which in such cases can only be relied upon to detect one 
from the other. 
That is their origin or, in other words, their disease-producing 
action. 
It needs no argument from me for the practical farmer to know 
that the Southern Cattle Plague will not produce hog cholera in his. 
hogs, or the latter disease the Southern Cattle Plague in his cattle. 
ON SOME INTERESTING DERIVATIONS OF 
MINERAL NAMES. 
BY F. M. ENDLICH. 
(Continued from January Number.) 
3. In addition to those mineral names which have undergone 
curious changes in the course of timé, there are others which show 
interesting etymological relations, and yet have descended to us in 
but slightly changed form. 
KERMESITE is derived from the Sansk. krimi, worm; Pers., 
kirm or kirmis, scarlet; Ar., alkirmis; Sp., alkermes; G. obs. 
Kermes, the “scarlet bug,” cochineal insect. Chermes, the drug- 
gists’ name for the substance, reached Spain from Arabia and thence- 
travelled to Italy and Germany.! 
The Sansk. form krimi has been retained in our Engl. crimson. 
It is also recognizable in the Lithuanian kirminis, worm. In It., 
Fr. and, later, Sp., the letter a was substituted for ¿i and e, resulting 
in carminio and carmine: whence the mineral name Carminite. 
1 ‘* Chermes vocant Arabes vnde nos chermesinum ; sev et vermilium 
vsurparunt quidam, a vermiculis exemptis a radice pimpinelle; 
coccum autem alio nomine dicitur scarlattum.”’ (Czesius, 1636.)
