I went to my university library and copied the numbers from the actual book "Some mathematical problems in biology".
The link in the description (http://katalog.ub.uni-heidelberg.de/titel/66489211) points to that book in the university library. They don't have a digital version of it, but you can go to Heidelberg and have a look at the physical copy. It's a beautiful city worth visiting.
Under https://archive.org/details/somemathematical0000symp_o1x7 you can find a digital scan of the book. You have to register (free) and log in to get access to the whole book for a limited time.

Hi, Mr Osthege,
I want to use this information for a tesis I am writing but I don't really know what is the validity of this information. I have been searching the internet for the exact numbers and databases of this population, but I continuously find images and websites that don't led to anywhere. Where did you get this information? I understand you put your source link, but I do not know how to use that website, and wanted to comment directly.
