Komentář k Licence:

Boerhaave website states '(vrij beschikbaar voor publicatie)'. '(freely available for publication)'. Moreover, Kamerlingh Onnes passed away in 1926, and even though the date is not mentioned on the website of the Royal Library we can be pretty sure that it is well before 1923, which makes it PD-US as well
