Letter from a medical colleague to Rossie.
"6th July, 1952
My dear Rossie,
Could you send me at your earliest convenience or even earlier, a U shaped glass cannula of the type used for insertion into the radial artery at arrteriotomy, and with it the information about source of supply - or did we have them specially made or blown for us. Don’t tell me you get them from Young’s! I have just spent a particularly blasphemous day showing Mr. Calvert and the anaesthetist here how to do an arrteriotomy. The result was a resounding success in that the pressure stayed at 80 throughout, the brain shrank away and pratically fell down the foramen magnum, and the angioma which was the subject of attack was removed with comparative ease, but what I could not tell you about the type of needles polythene tubes and cannula that should not be used would be not worth printing (not to mention unprintable). Thanking you, as they say, in anticipation, because we have another very similar one to do shortly.
