GDG- Civil War Medical Question

[Ginny Gage]

Esteemed Members,

Mary Davis and I are working on a Scavenger Hunt for our Civil War
fundraising group we belong to.

We¹re looking for a good general Civil War medical question, and someone
suggested that we ask if there were thermometers during the Civil War, and
how many?  Evidently they were used then, but there were only about a dozen.

Does anyone know if this is true?  And, by a dozen, does that mean both
armies had a dozen each, did only the Union army have them, or what?

Is there any place I can look up this information?

Thanks for your help.

Ginny Gage
