Don't you think, that if this was from 1890...the "fluid" that is perserving the "dragon" would be a little bit murkier than what it is?
Formalin has remained the most commonly-used fixing agent in histology, and was blessed with an interesting introduction worth recalling. It was originally discovered by Butlerov in 1859, but only became a viable commercial proposition when in 1868 Hoffman successfully synthesised formalin from methanol. In 1892 a German firm approached an industrial chemist named Blum for formalin to be tested as a possible antiseptic agent. He noticed that while handling the formalin the skin on his fingertips became hardened, a very similar effect to the one alcohol had on tissue during fixation. Acting on this, Blum proceeded to test formalin as a potential histological fixative, and in 1893 sent his final results to the famous German histologist Carl Weigert, who gave it the teutonic equivalent of the 'thumbs up'. On the post-fixation decalcification of calcified tissue, the origins are not as well documented, but it is on record that the famous English microscopist, Quekett, described the use of hydrochloric acid for this purpose back in 1848.
Some reptiles are live bearers and others lay eggs.
Egg Layers include:
All turtles, All tortoises, All crocodilians,
Some lizards: Iguanas, Water dragons, Geckos, Veiled chameleons, Panther chameleons, Monitors
Snakes: All pythons, Kingsnakes, Milksnakes, Rat snakes, Corn snakes
Solomon Island skink, Blue-tongue skink, Shingle-backed skink
Some chameleons :
All boas, All vipers, Garter snakes
Most reptiles lay eggs. The act of laying eggs is called oviposition. Reptiles that lay eggs are called oviparous. Some reptiles bear live young, and the term for this is viviparous. Technically, a female that lays eggs is said to be gravid when she is holding eggs inside of her. A female that gives birth to live young may correctly be called pregnant.
Here is how to tell the sex!
Male and female reptiles do not have external genitalia to help owners determine the sex of a herp. Males and females do possess different reproductive organs, however. The male possesses two testicles, housed inside the body. The male also has a copulatory organ, either a single penis (turtles and tortoises, crocodilians) or a pair of hemipenes (lizards, snakes) that can often be seen as two bulges behind the cloaca at the base of the tail. The penis or hemipenis is not connected to the urinary tract, and is strictly an organ of reproduction. Lizards and snakes can be sexed by the use of a probe that is inserted into the cloaca, directed towards the tail, off of the midline. The probe will travel farther in the male than in the female.
Here is a little on mating
While it would seem that reproduction is a natural event, without correct circumstances, such as a balanced diet and a suitable environment for egg-laying, eggs may not develop normally or be laid in a timely manner. Owners are often surprised to find that their single pet female lizard has developed eggs. A healthy adult female does NOT need the presence of a male to become gravid.
For fertilization, a male reptile inserts either one of his two hemipenes into the female's cloaca, or the single penis is inserted. Before actual copulation, the pair usually engages in some type of ritualized courtship. After copulation, sperm can be stored for up to six years, and this stored sperm can fertilize subsequent clutches without additional contact by a male.
Using the green iguana as an example, even without a male present to fertilize eggs, a healthy adult female may begin developing eggs. The process begins with the ovaries, where eggs are stored. The ovaries are located inside the body. Most green iguana females become mature when they are between two and four years of age. At that time, follicles begin developing in the ovaries. Each follicle is composed of a tiny egg and a sac filled with yolk. The follicles then detach and move into the oviducts where the egg white is added, and then a shell is placed around the yolk and white. The gravid female usually will not eat for three to six weeks prior to laying her eggs. It makes sense since her abdomen will be full of eggs in the oviducts, and the stomach is quite compressed, and there is little space for food in the stomach
Hope some of this helps.
I find it fun to let myself believe that there is a possibility that they once might have existed. They probably didn't but then again there are those that believe that there was an Atlantis which was ruled by a Monitor, Vampires, Ailens, Bigfoot, Nessi, Chupa, Sandman, Boogieman, Ghosts and other stuff.
Anyway thats just me!
