From three months to six will be needed to cure bad cases. Mange Proper is also caused by a parasite or acarus, called the Sarcops canus. Unlike eczema, this mange is spread from dog to dog by touch or intercommunication, just as one person catches the itch from another.
Or a living product of galvanic action, Like the acarus bred in Crosse's flint-solution? Speak, thou Cyano-Rhinal! Many things thou askest, jackknife-bearing stranger, Much-conjecturing mortal, pork-and-treacle-waster! Pretermit thy whittling, wheel thine ear-flap toward me, Thou shalt hear them answered.
The insects produced by both experimentalists seem to have been the same, a species of acarus, minute and semi-transparent, and furnished with long bristles, which can only be seen by the aid of the microscope. It is worthy of remark, that some of these insects, soon after their existence had commenced, were found to be likely to extend their species.
Lyonet states that during summer this mite is viviparous. Acarus farinæ DeGeer, as its name indicates, is found in flour. Other species have been known to occur in ulcers. According to Prof. Verrill it is readily visible to the naked eye and swarms on horses afflicted with the mange, which is a disease analogous to the itch in man.
Wash carefully once a week, using the ointment when skin is dry, or the lotion to allay irritation. Contagious Skin Diseases. These are usually called mange proper and follicular mange, or scabies. I want to say a word on the latter first. It depends upon a microscopic animalcule called the Acarus folliculorum.
On the hypothesis here brought forward, the acarus Crossii was a type of being ordained from the beginning, and destined to be realized under certain physical conditions. When a human hand brought these conditions into the proper arrangement, it did an act akin to hundreds of familiar ones which we execute every day, and which are followed by natural results; but it did nothing more.
The Acarus, at first supposed to be a new and hitherto unknown creature, is now acknowledged to be one of a very familiar species, a species which may have deposited its ova, and propagated its kind, since the commencement of the present order of things, and whose eggs might very well resist the action even of nitrate of copper, since the creature itself could live in that poisonous mixture.
Audacious spirits even hazarded the conjecture that primitive life itself might have originated in a natural way: had not, but recently, an investigator who brought a powerful voltaic battery to bear on a saturated solution of silicate of potash, been startled to find, as the result of his experiment, numberless small mites of the species ACARUS HORRIDUS? Might not the marvel electricity or galvanism, in action on albumen, turn out to be the vitalising force?
All the time I had been in Ceram I had suffered much from the irritating bites of an invisible acarus, which is worse than mosquitoes, ants, and every other pest, because it is impossible to guard against them.
Weekes's acarus should show himself all of a sudden, as they said he did, in certain mineral mixtures acted on by electricity. The Landlady was off soundings, and looking vacant enough by this time. The Master turned to me. Don't think too much of the result of our one experiment.
