William Gilbert: Terrella with a weak part which is marked with cross-lines.

Thursday, April 28th, 2011

[ZB Magnet 2] William Gilbert, De Magnete (London: Petrus Short, 1600), Zentralbibliothek Zürich, Alte Drucke und Rara, XVI.28, p. 155.
AB is a terrella imperfect in parts and of unequal power on the circumference. The needles H and L vary, because they are placed in a decayed part and incline towards the sound parts (where the needles C, D, E, F are placed). Needle O does not deviate because it is placed in the middle of the decayed part.

Iron will obtain north-south direction when it is hammered and heated properly: “Let the smith stand facing north, with back to the south, so that as he hammers the red-hot iron it may have a motion of extension northward.” (Gilbert, De Magnete (translated by Mottelay) p. 211ff) [ZB Magnet 2] William Gilbert, De Magnete (London: Petrus Short, 1600), Zentralbibliothek Zürich, Alte Drucke und Rara, XVI.28, p. 139.

Sampurna Chattarji: Bodies Tend To Come Together (In Dreams)

Monday, April 18th, 2011

Your mouth is full of teeth, sharp points on my mouth.
Your mouth is too small, I whisper, giggling, into your mouth.
Your mouth is sucking all the air out of my mouth.

Your mouth is a shark.
