Biology of the Reptilia covers behavior, development, ecology, neurology, and physiology, in addition to morphology which was fundamental to the rest, all in 22 volumes and nearly 13,800 pages.

As he wrote in volume 1, Carl Gans’s goal was “to facilitate future work rather than place a tombstone upon past knowledge.”

Surveys of the literature, he noted, had disclosed critical gaps in our knowledge and new investigations were thus needed to complete many of the chapters. He expected that this series would not be the last word, and hoped it would “prove germinal in inducing additional study.”

In 2012, there were 16 car models approved for New York taxi service. All of them must be painted in corporate yellow and marked. You can work for a taxi company (they will give you a car on lease) for a percentage or stable deductions. You can work for yourself, but then all the start-up costs fall on you. An old car uber costs about $3,000; a new one starts at $30,000. Insurance costs $5,000-10,000 a year. You will need to buy another taximeter and checkers, which in total is about $500. With a new car and a driver over the age of 21, you can work with services like Uber. There are also borough taxis, that is, district taxis and services from nearby cities. They don’t have to be yellow, but they can’t pick up people off the street. Is it profitable? The initial investment in a license seems huge, but there are never enough applicants to become a taxi driver in New York. Obviously, this makes financial sense, and the real income of taxi drivers exceeds estimates.
