days without taking any food or drink but sugar water and honey. 
As already stated, the natives of Miana take these bugs into their 
hands without any danger. How fortunate it is that these formidable 
insects do not nestle in the clothing, for they would soon be carried 
all over Persia. 
Tooth-ache Mite, Ixodes ? Odontalgia, new species. Aptefa Acaridse. 
A minute brown mite with pale margin and legs, the penultimate joint of the lat¬ 
ter longest, the end of its body transversely truncated and strongly notched in the 
middle. Found on the root of a newly extracted tooth. 
In addition to the ticks and mites which infest the skin of man and 
animals externally, are others which are internal, occurring in differ¬ 
ent paits of the interior of the body. One of the most common and 
best known of these is the itch-mite, Sarcoptes Scabiei, which abounds 
in the pustules of the human itch. Other mites occur in ulcers, and 
like the itch-mite may communicate the same ulcers to other persons. 
An interesting case in proof of this is reported in Cooper’s Microsco¬ 
pic Journal, 1S42, vol. ii, p. 65. A negro sailor was received into 
the Seaman s Hospital Ship, affected with large ulcers on the soles of 
his feet, of a peculiar character. He appeared to have received this 
malady from wearing a pair of shoes a day or two, which he had had 
from another negro whose feet were similarly diseased. In these 
ulcers a mite occurred, a figure of which is given, which shows it to be 
a species quite different from the itch-mite. This sailor had come 
direct from the East Indies, from a locality where no such malady as 
this was known. The other negro was from Sierre Leone, where, it 
is stated, a sort of itch is prevalent, which ulcerates and is very diffi¬ 
cult to cure. It is added that in some water from the Sinoe river, on 
the coast of Africa, a whole mite and broken fragments of others were 
found, similar in every respect to the one from these ulcers. 
It is reported that in one of the quarters of Paris at a former period 
persons were frequently affected with mites under the eyelids, which 
a woman there became considerably noted for removing with a silver 
needle. Another species, named the dysentery-mite, from its abound¬ 
ing in the evacuations of dysentery patients, is stated to occur in all 
parts of the alimentary canal. And even in the brain these insects 
have been met with, both on its surface and deep in its interior, 
lermann reports that in the post-mortem examination of a soldier who 
died in the military hospital of Strasburg from a fracture of the skull 
on separating the two hemispheres of the brain and taking out the pia-
