The hasty marriage incites much gossip at the asylum, prompting the Marquis to write a farce to be performed at a public exhibition, which Royer-Collard and Simone attend. The audacious play, a parody of the good doctor's own misogynist domination of his virginal bride, is titled "The Crimes of Love". The performance is interrupted when the inmate Bouchon molests Madeleine off-stage, prompting her to hit him in the face with an iron. The Abbé is seen publicly comforting Madeleine. Royer-Collard shuts down the public theater and demands that the Abbé do more to control the Marquis, or he will inform the ministry that the inmates are running the asylum. Infuriated, the Abbé confiscates the Marquis' quills and ink. The Marquis's wife visits him and he takes out his frustration at not being able to write on her; she retaliates by asking a surprised Royer-Collard that the Marquis be entombed forever.
This will be the instructable preceding one I plan to release soon. I want to use porcupine quills in a craft however just using white would not bring my concepts to life as I envision them, so I will show you a simple way of dying these little quills so you can have colorful projects too!
I easily found mine on ebay for pretty cheap. However it is simple enough to pull them out of a porcupine itself if you happen to stumble upon one. Just be careful, they're sharp! Try to buy or scavenge medium sized quills, from around an inch or longer and then a few millimeters in diameter.
Unless you plan to leave the barbs on for some reason you'll have to cut them off as well as the follicle part. If you need a sizable amount of quills, I recommend lining them up until you have about 3/4 of an inch of quills side by side and line up the areas where the white turns to black. Now when you cut the barbs off I've seen it's best to dip the ends into a little tub of water and just snip the ends off with scizzors. This will prevent them from going flying everywhere and causing trouble for you or others. Then line up the follicle ends and repeat the process. When you are done you will have these small tubes that look like they're filled with some sponge material.
Place all of your barbless quills into a small bowl. Add a few drops of dish soap to eat away at the grease and then run warm/hot water over it and let it soak until the water gets room temperature. Drain the water and repeat the process (I find placing a paper towel over the bowl and flipping it upside down works best for draining). Then once they are as bright and clean as you think you can get them set them out to dry.
Get a few packets of Kool-aid in whatever color you want the quills to be. Then in a shallow pan put just enough water to cover the quills (don't put them in yet) and turn it on "LOW". You don't want the water to boil, just get hot. Add you Kool-aid and mix it up. Next place your quills in and work them around in the water with a fork until they get to the color you'd like whenever you lift them out of the Kool-aid.
When the quills have reached the color you like lift them out with the fork and move them to a bowl with vinegar in it. Work them around to get any excess Kool-aid off and then remove them and place on a paper towel to dry. The vinegar will help set the colors.
Some mammals have modified hairs that are enlarged, stiffened, and strengthened to form spikes of different shapes and sizes. These structures, called spines or sometimes quills, always have a thick, hard, outer tube of keratin (the fibrous protein that makes up all hair as well as claws, nails, and horn sheaths) and tapered, pointed tips.
Spines and quills evolved independently at multiple places and times in the mammal tree of life; thus, they are an example of convergence. The oldest mammal known to have enlarged, hardened hairs for defense is Pholidocerus, an extinct ancestor of the hedgehog that lived over 40 million years ago. However, hairs do not fossilize as readily as other structures like teeth and bones, so spines and quills may have evolved much earlier.
Today, spines or quills are found in four major groups of living mammals: hedgehogs (Erinaceomorpha: Erinaceidae, Erinaceinae), tenrecs (Afrosoricida: Tenrecidae, Tenrecinae), echidnas (Monotremata: Tachyglossidae), and rodents (Rodentia). The latter group includes Old World and New World porcupines (Hystricidae and Erethizontidae, respectively), the spiny rats (Echimyidae), and the Old World rats and mice (Muridae), all of which have species with spiny pelage.
New World porcupine quills are such formidable and effective weapons that they have even been known to kill would-be predators like dogs and foxes. The reason that these quills are so dangerous becomes obvious at the microscopic level (Fig 1). The tips of each quill are incredibly sharp and able to pierce through skin more easily than an 18-gauge hypodermic needle (about the same size of the quill). Once it has entered the skin, its microscopic backward-facing barbs prevent the quill from being removed without causing significant pain and damage to surrounding tissues. To make matters worse, the quill tip breaks off easily so that it remains in the attacker, and it can work its way deeper and deeper into the skin over time with each muscle contraction or movement. In his book The North American Porcupine, researcher Uldis Roze describes a New World porcupine quill breaking off in his bicep, only to emerge two days later in his forearm (p. 24)!
But how do porcupines protect themselves from being injured by their own quills? Indeed, many examples from scientific and anecdotal literature show that New World porcupines fall relatively frequently from trees, presumably forcing their own quills into their skin. One way that porcupines appear to limit self-injury is through natural antibiotics in their quills. Roze et al. (1989) found that the quills of New World porcupines are coated in fatty acids from exocrine secretions that prevent bacterial growth, likely to prevent infection from self-inflicted wounds.
Spines offer a clear advantage to species like porcupines, whose quills are known to deter, and sometimes even kill, predators. However, the spines from the remaining rodent families (e.g., Muridae and Echimyidae) are comparatively ineffective at warding off attackers, so their function is not fully understood.
This observation led Vincent and Owers to hypothesize that hedgehog spines provide more than just passive defense from predators. In an experiment that tested the strength and mechanical properties of quills and spines, these scientists found that hedgehog spines are highly elastic to strong impact forces. There are many reports of hedgehogs climbing trees and walls then descending by simply rolling and dropping to the ground. It is therefore possible that hedgehog spines evolved as shock absorbers from falls rather than defense from predators.
While hedgehog tenrec spines are certainly used in defense and are also hypothesized to function both in anointing (Eisenberg & Gould 1970) and shock absorption (Vincent 1986), they may have another function: communication. During courtship and marking behaviors, Echinops often moves its body muscles rhythmically, causing its dorsolateral quills to rub against each other and produce a low sound.
The common or tailless tenrec (Tenrec ecaudatus) has a structure similar to the stridulating organ of Hemicentetes, although it is only present in juveniles. In the common tenrec, spines (Fig. 5) are molted by juveniles and are replaced by softer fur in adults, with the spines on the stridulating organ replaced last. The stridulating organ is not as active in the common tenrec as it is in streaked tenrecs; the common tenrec vibrates its spines only when it is frightened, often in conjunction with the erection of quills on its neck and back, and the sound it produces occurs at a reduced frequency range (12 to 15 KHz). In adult common tenrecs, even after the stridulating organ disappears, the fur on that area of the back vibrates rapidly when individuals are threatened or scared.
In the sixth book of the Mesaland Series, meet a strange little animal sprinkled with needle-sharp quills--Mr. Porcupine! Whoops, he outsmarts Three-Toes the coyote. Crunch-crunch, he gobbles Rancher Brown's saddle. Ouch, he tangles with Fussy Bluejay.
Some time ago, a conversation about unusual fly tying materials started out withsnake skin for the Mamushi Kebari. When I mentioned that the snake is venomous, the other tyer lost interest. Always trying to be helpful, Isuggested roadkill as perhaps a safer way to acquire a snake skin. Inreturn, he suggested that roadkill might be a safer way to acquireporcupine guard hairs, which make very nice quill bodies. As soon as hementioned the words "porcupine" and "quill" I immediately thought ofporcupine quills (simply amazing how the human mind works). I told himhe could keep the guard hairs, but I would be interested in some quills.
Of course, since we were talking about fly tying, he assumed I was thinking of usingthe quills for fly bodies but I had already left fly tying and was wellinto micro fishing mode. Porcupine quills, I figured, ought to makereally nice floats for micro fishing. The American porcupine's quills arebright white beyond the dark pointy tip. Bright white is easy to seewhen looking down against the dark surface of a lake or slow movingstream, but much harder to see when looking up at the sky (which has tobe why nearly all baitfish have white bellies).
Porcupine quillfloats are generally made from the quills of African porcupines. At upto 9 inches long (or more), the quills are huge compared to the quillsof American porcupines, which are only 2 to 3 inches long. The floats are saidto be quite sensitive.
It turned out the guy I was talking to actually had some quills, which he graciously offered to send me. I don't know if they were from roadkill - he didn't volunteer the information and I didn't ask. I gratefully accepted and within a few days I had a little box full of porcupine quills (and yes, those suckers are SHARP).
