3.From under make minor tube tubes from minor tube tubes?
 variation 
Is from under (re)mak(ing) minor tube tubes(tubules) from two minor tube tubes(tubules)?

Are "tube" and "tubes" different in the original spelling? It's three times "fo-fheadan" and one time "fho-fheadan" in your transcription, is this a typo or some actual difference in how these labels are written in the manuscript?
