Um...., In your post, you just posted a broken link to something (I don't know what "It" is), followed by a translation of the original book--- not "a translation of a review or comments on it". So, I posted a link to a copy of the original book in its original language.- robphy

High School Looking for an English translation of Levi-Civita's 1926 paper "Sur l'écart géodésique" ("On the geodesic deviation")
