Example text

Collectively, they contain much of what is known about the natural history of mammals of the world. How many scientific specimens of mammals have been gathered after several centuries of collecting? A good estimate is six million (in 1981 the most recent survey of all collections showed that there were five million specimens; I have allowed for some growth). That number includes all specimens of the roughly 4,600 mammal species of the world. More than four million are of bats and rodents, the most abundant small mammals in nature.

That number includes all specimens of the roughly 4,600 mammal species of the world. More than four million are of bats and rodents, the most abundant small mammals in nature. 006 percent of the number of mammals killed each year in the United States by pet cats. 00000001 percent of the yearly catch of mammals by pet cats. This means that only one specimen out of fifty million that would have been killed by a cat ended up in a museum. The mammalogists got one animal; the cats got 49,999,999. You might think, “Well, small mammals are one thing and sure, there are forty million free-tailed bats in a single cave in Texas on a single day (six times the number of specimens that exist in all of the collections of the world), but what about big mammals?
