EDITORIAL COMMENT. 
The Hkim-( Ai'KLLiM Incident in the Ixteknational Geo- 
T-OGICAL ("ONGRESS AT ZuRICH. 
An answer to a letter addressed by the undersigned to Prof. 
Capellini contains tlie following: 
"The first prize, awarded to M. Heim was 2,000 francs. The 
second was awarded to M. A. Karpinski, 1,200 francs. The 
third, 800 francs, was awarded to M. Maillard. Heini had 
had the illustrations and manuscript in 1881-1882. He had 
returned them with the greatest punctualit3\" * * [The 
Congress of Bologna was held from Monday, Sept. 26, 1881, to 
Sunday, Oct. 2, 1881. P. F.] * * "I have his card ac- 
knowledging the receipt of manuscript again dated Dec. 16, 
1891. He added 'I thank you ver}^ much for the trouble you 
have taken to loan it to me.' The manuscript was finally re- 
turned March 11, 1895. Dec. 16, 1891, to March, 1895, makes 
three years and three months." 
The documents were therefore borrowed twice, but in the 
statement w^hich I took down as it was made, the fact of the 
first return was accidentally omitted. Although I cannot 
consider myself responsible for the error, I regret having been 
led into it and now publicly correct it. Prof. Heini did not 
borrow and retain the manuscript and illustrations of his 
first prize essay before the International Congress of Bologna 
for thirteen years, but onl}'^ for three years and three months. 
I have already acknowledged my error in stating that he 
received only 1,200 instead of 2,000 francs, an error which is 
the less excusable because the facts are clearly set forth on 
page 87 of the Bologna volume. Persifor Frazer.
