cannot be easily improvised in the Barcelona laboratory, or a special proceedure that may require some training before it can be successfully performed. If such is the case, the acquisition of the necessary apparatus, or of special chemicals, or the necessity for preliminary work would mean further delay after the publication of the technique. All this would be added to the delay involved in the printing of the paper and the time required for it to reach Barcelona. I, therefore, ask you to give me whatever information you think compatible with your reserve concerning such special apparatus, chemicals, or operations necessary for the successful preparation of the pancreatic extract, and whatever other points you think might shorten the time necessary for starting the preparation after the details have been published. Would you kindly let me know the name of the journal in which the article will appear?
After one year of residence in this country, I am leaving for Barcelona on June 1st. If you think that a short trip to Toronto will be of advantage, I shall be glad to undertake it.
Thanking you in advance for your kind attention in the matter, I am,
Yours very truly,
P.S. I enclose a letter received some time ago from the patient and another from his mother. I hope that you will understand their significance, and that they will help you to realize my human interest in the matter.
Until I left Barcelona, a year ago, I was keeping a careful record of this patient since February 1920, and I am sure that Dr. Pi Suner who was kind enough to take care of him during my absence continued it; this fact and the severity of the case will make the trial of Insulin in it, if it can ever be done, one of some scientifical interest.
