THE COLOR OF FLOWERS. 



The red pigment of several kinds of 

 t>erries was formerly regarded as a 

 blue pigment reddened by acid. Ber- 

 zelius, in 1837, found this was not so 

 with some berries and leaves he exam- 

 ined. Julius Wiesner, in 1802 and 1872, 

 after a series of experiments, came to 

 a conclusion contrary to Berzelius, that 

 the original and actual color of an- 

 throcyan was blue, not red. 



To settle the dispute P. Q. Keegan 

 (Nature) made a research this year, 

 and concludes that there are different 

 stages in the development of the floral 

 pigment. In the lower stages the nat- 

 ural color is red, whatever the chromo- 

 gen may be, and so far Berzelius was 

 right. In the higher stages, however, 

 the natural color of anthrocyan is blue, 

 or, at least, with some chromogens be- 

 comea capable of forming blue com- 

 pounds or lakes with alkalis and cer- 

 tain metallic salts. This investigation 

 also shows that chromogenes exist 

 which, unless under very exceptional 

 conditions and circumstances, are in- 

 capable of producing blue pigment, and 

 these in all stages naturally develop 

 into a red, the brilliancy of which, 

 when contrasted with that of a blue 

 accidentally obtained in an allied spe- 

 cies, attests its real, original and proper 

 character. 



RICHMOND, IND.— On April 24 the 

 Quaker City Machine Co., makers of 

 the Challenge ventilating apparatus, 

 admitted a new partner in the person 

 of the eldest son of Mr. and Mrs. J. A. 

 Evans. To be sure, he will not be of 

 age till 21 years hence, but he is al- 

 ready making things lively, and is 

 giving John points on several things. 

 Congratulations.
