I remember having to use special oils to use some high magnification microscope lenses in a process known as 'oil immersion microscopy'. I didn't read much about how it worked before but I assume it is the same process. There was no other way for me to get the magnification I needed to count the reletive number heterocyst cells in strands of cyanogenbacteria for my biology coursework. I would suggest to the author that they buy some microscopy oils as they will have a higher refractive index to water. https://en.wikipedia.org/wiki/Oil_immersion https://en.wikipedia.org/wiki/Oil_immersion
