This is called bithermal caloric testing. This test will show the nerve damage by comparing responses from the water on either side-in normal ears each side responds with the same rapid side to side eye movements (nystagmus). When one side is damaged, the nystagmus / eye movements will differ, proving the damage.
The common law tradition emerged in England during the Middle Ages and was applied within British colonies across continents. The civil law tradition developed in continental Europe at the same time and was applied in the colonies of European imperial powers such as Spain and Portugal.nly in the seventeenth century did common law triumph over the other laws, when Parliament established a permanent check on the power of the English king and claimed the right to define the common law and declare other laws subsidiary to it.
The differences between common law and equity Common law evolved over time as a judge made law (according to doctrine of precedent.) In common law the king was the head of the government. Common law was the law administered by the royal courts and as such a more standardised set of rules based on customary law was gradually enforced throughout the whole of England and countries derived from England. E.g. Australia, Canada New Zealand and the United States.
