Question: How many legs does the animal, in which Karl Kraepelin discusses in "Scorpiones und Pedipalpi," have?

Documents:
source: Scorpion
text: Scorpion Scorpions are predatory arachnids of the order Scorpiones. They have eight legs and are easily recognized by the pair of grasping pedipalps and the narrow, segmented tail, often carried in a characteristic forward curve over the back, ending with a venomous stinger. Scorpions range in size from 9 mm / 0.3 in. ("Typhlochactas mitchelli") to 23 cm / 9 in. ("Heterometrus swammerdami").

text: Karl Kraepelin Karl Matthias Friedrich Magnus Kraepelin (14 December 1848 Neustrelitz – 28 June 1915 Hamburg), was a German naturalist who specialised in the study of scorpions, centipedes, spiders and solfugids, and was noted for his monograph ""Scorpiones und Pedipalpi"" (Berlin) in 1899, which was an exhaustive survey of the taxonomy of the Order Scorpiones. From 1889–1914 he was Director of the "Naturhistorisches Museum Hamburg ", which was destroyed during World War II, and worked on myriapods from 1901–1916.

text: Kraepelinian dichotomy The Kraepelinian dichotomy is the division of the major endogenous psychoses into the disease concepts of dementia praecox, which was reformulated as schizophrenia by Eugen Bleuler by 1908, and manic-depressive psychosis, which has now been reconceived as bipolar disorder. This division was formally introduced in the sixth edition of Emil Kraepelin's psychiatric textbook "Psychiatrie. Ein Lehrbuch für Studirende und Aertze", published in 1899. It has been highly influential on modern psychiatric classification systems, the DSM-IV-TR and , and is reflected in the taxonomic separation of schizophrenia from affective psychosis. However, there is also a diagnosis of schizoaffective disorder to cover cases that seem to show symptoms of both.

text: Boiga kraepelini Boiga kraepelini, commonly known as the square-headed cat snake, Kelung cat snake, or Taiwanese tree snake is a species is a species of mildly venomous colubrid snake found in East and Southeast Asia (Taiwan, China, Vietnam, and Laos). Its specific name "kraepelini" honours Karl Kraepelin, a German naturalist. The common name Kelung cat snake refers to its type locality, Keelung in northern Taiwan.

source: Solifugae
text: Solifugae Solifugae is an order of animals in the class Arachnida known variously as camel spiders, wind scorpions, sun spiders, or solifuges. The order includes more than 1,000 described species in about 153 genera. Despite the common names, they are neither true scorpions (order Scorpiones) nor true spiders (order Araneae) – though they are more closely related to scorpions than to spiders. Much like a spider, the body of a solifugid has two tagmata: an opisthosoma (abdomen) behind the prosoma (that is, in effect, a combined head and thorax). At the front end, the prosoma bears two chelicerae that, in most species, are conspicuously large. The chelicerae serve as jaws and in many species also are used for stridulation. Unlike scorpions, solifugids do not have a third tagma that forms a "tail". Most species of Solifugae live in dry climates and feed opportunistically on ground-dwelling arthropods and other small animals. The largest species grow to a length of 12 - , including legs. A number of urban legends exaggerate the size and speed of the Solifugae, and their potential danger to humans, which is negligible.

source: Tokummia katalepsis
text: Tokummia katalepsis Tokummia katalepsis is a fossil arthropod from the Burgess Shale as found in a quarry in Marble Canyon in Canada. It is an early member of Mandibulata. The fossil is 508 million years old. The animal has maxillipeds, mandibles, ring-shaped body segments, and subdivided basipods. At the front of the animal are mandibles with pincers. This is the oldest fossil with pincers. The speculation is that "T. katalepsis" grabbed soft bodied prey with the mandibles and them chopped them into pieces so that it could eat. It has more than 50 pairs of legs. The animal is about 10 cm long and has a two piece carapace on its back. It was a bottom feeder, being able to walk on the sea floor, and to occasionally swim. The animal legs have endites which are small spikes on the legs. It has one pair of antennae.

source: Limbs of the horse
text: Limbs of the horse The limbs of the horse are structures made of dozens of bones, joints, muscles, tendons and ligaments that support the weight of the equine body. They include two apparatuses: the suspensory apparatus, which carries much of the weight, prevents overextension of the joint and absorbs shock, and the stay apparatus, which locks major joints in the limbs, allowing horses to remain standing while relaxed or asleep. The limbs play a major part in the movement of the horse, with the legs performing the functions of absorbing impact, bearing weight, and providing thrust. In general, the majority of the weight is borne by the front legs, while the rear legs provide propulsion. The hooves are also important structures, providing support, traction and shock absorption, and containing structures which provide blood flow through the lower leg. As the horse developed as a cursorial animal, with a primary defense mechanism of running over hard ground, its legs evolved to the long, sturdy, light-weight, one-toed form seen today.

text: Illusion costume An illusion costume is a costume that fools the eyes by making it seem that the person in the costume is riding an animal, being held by another person (which is part of the costume), or many other things. The most common is the rider, in which the "rider" (person) gives the illusion of riding an animal; the person's legs go through the hollowed-out animal legs, along with fake legs dangling off the wearer's body to finish off the illusion.

source: Jerusalem (Mendelssohn)
text: Jerusalem (Mendelssohn) Jerusalem, or on Religious Power and Judaism (German: "Jerusalem oder über religiöse Macht und Judentum" ) is a book written by Moses Mendelssohn, which was first published in 1783 – the same year, when the Prussian officer Christian Wilhelm von Dohm published the second part of his Mémoire "Concerning the amelioration of the civil status of the Jews". Moses Mendelssohn was one of the key figures of Jewish Enlightenment (Haskalah) and his philosophical treatise, dealing with social contract and political theory (especially concerning the question of the separation between religion and state), can be regarded as his most important contribution to Haskalah. The book which was written in Prussia on the eve of the French Revolution, consisted of two parts and each one was paged separately. The first part discusses "religious power" and the freedom of conscience in the context of the political theory (Baruch Spinoza, John Locke, Thomas Hobbes), and the second part discusses Mendelssohn's personal conception of Judaism concerning the new secular role of any religion within an enlightened state. In his publication Moses Mendelssohn combined a defense of the Jewish population against public accusations with contemporary criticism of the present conditions of the Prussian Monarchy.
