Notes and Brief Articles 39 



An excellent sketch of the life and work of Dr. Howard A. 

 Kelly, of Baltimore, contributed by Dr. Thomas S. Cullen, with 

 a bibliography of 485 titles prepared by Miss M. W. Blogg, ap- 

 peared in The Johns Hopkins Hospital Bulletin for October, 

 1 91 9. As Dr. Kelly is only about sixty and appears very much 

 younger, we may expect many additions to his extended bibliog- 

 raphy before it is ready for final binding. 



An interesting and helpful bulletin by Jones, Miller, and Bailey 

 cn frost necrosis of potato tubers appeared in October, 1919, from 

 the Wisconsin Agricultural Experiment Station. This injury is 

 due not to solid freezing, after which the tubers collapse upon 

 thawing, but to partial freezing that does not affect the tubers 

 externally. When cut open, however, characteristic discolora- 

 tions appear, which might easily be attributed by the uninitiated 

 to the attack of some fungus. 



Those interested in mosaic diseases, which are quite in the 

 public eye at this time, will welcome an article by Schultz and 

 others in the Journal of Agricultural Research for September 

 15, 1919, dealing with potato mosaic. The article was read in 

 manuscript at the conference of potato pathologists on Long 

 Island last June. There are several illustrations, some of which 

 are in natural colors. 



" The Farmers' Dictionary and Household Cyclopedia," by the 

 late Dr. George Thomas Surface, formerly on the Yale Univer- 

 sity Staff, has just been published in a limited edition by the 

 author's father, Rev. F. D. Surface, of Blacksburg, Virginia. 

 It is a handbook of 730 pages with up-to-date information on 

 practical farming and domestic science arranged in alphabetical 

 order for the use of farmers and their wives. As the facts are 

 mostly taken from agricultural publications, a copy of this work 

 would no doubt prove very valuable and handy in any agricul- 

 tural experiment station. It is splendidly written, well printed, 

 and costs little.
