When I got my Gilbert telescope one Christmas, I also got the Gilbert microscope. I was never into microscopes much, we used them occasionally in school. I would occasionally get the leg of a bug. But I noticed that nearly all the cheaper microscopes always had a prepared slide of shrimp eggs. Why was that? Was there something about shrimp eggs that was supposed to be special.

Shrimp eggs are the only eggs that will fit  on a microscope slide. Maybe flea eggs. Do fleas lay eggs? confused1.gif

I would guess it's because shrimp eggs are more interesting.

 

Fleas do indeed lay eggs.

And if perchance they should hatch you have shrimp instead of fleas.   grin.gif

It's probably a regional thing? In my country (Belgium) those cheap microscopes and microscopy sets usually had a slide of silver berry scally hairs.
Those larger microscopy sets usually had a small frog preserved in formaldehyde and a dried butterfly as well.
For some mysterious reason they also had a few unusable chemicals: canada balsam (unusable without propper alcohols and xylene) and methylene blue solution (pretty much useless in contradiction to what many people think up to these days).
And a few unusable utensils as well: a few test tubes and a test tube rack, a pestle and mortar and so on.

I dunno about the mounted slide of shrimp eggs.  Maybe the boss's original intent was to 'freeze' them in various stages of hatching.  That might be educational and interesting to see.  Brine shrimp eggs will hatch under the right conditions, making a good subject to try to observe at lower powers.  Remember the ads in comic books for 'sea monkeys'?

 

I remember getting my first microscope, a holiday present when I was about 12.  It came in a bi-fold metal case, along with most of the junk Microscopy mentioned.  I'd a heck of a lot rather had an electric illuminator than a dead frog, fish, and crayfish....
