Flush toilets were widely available from the mid to late 19th century. Although Thomas Crapper did not invent the flush toilet, he was a leading manufacturer.
The bowl drain is visible at the rear of the bowl, connected to the waste pipe.

A flush toilet (also known as a flushing toilet, water closet (WC) – see also toilet names) is a toilet that disposes of human waste (principally urine and feces) by using the force of water to flush it through a drainpipe to another location for treatment, either nearby or at a communal facility, thus maintaining a separation between humans and their waste.

Previous population surveys had used conventional methods to estimate the size of the wild panda population, but using a new method that analyzes DNA from panda droppings, scientists believe the wild population may be as large as 3,000.
