THE NEW YORK JOURNAL OF PHARMACY 



Advisory Committee consisting of mem- 

 l)ers of the pharmaceutical profession. 

 /Vmoni^ the appointees are the following: 

 Dr. H. li. Rushy, Dr. Wm. J. Schief- 

 felin, Dr. Wm. C. Anderson, Dr. Jacob 

 II. Rehfuss, Mr. J. Leon Lascoff and 

 Mr. Thomas Lamb. 



Mr. Mayo introduced Mr. Charles W. 

 Holzhauer of the- Class of 1906, who pre- 

 sented a paper on "Profit Making Win- 

 dow Displays," showing lantern slides 

 of those windows which he has found 

 profitable and laying down the principles 

 which govern successful window display 



advertising. Mr. Holzhauer was fol- 

 lowed by Mr. N. Zimmerman of the edi- 

 torial staflf of Printers' Ink, who pre- 

 sented the results of investigations made 

 by him of window displays in various 

 lines. Mr. Thomas Lamb and Mr. John 

 Ferrier gave their personal experiences 

 which clearly demonstrated that the 

 style and method of wnndow dressing de- 

 pended entirely upon the locality and the 

 class of customers. 



Before adjournment, a standing vote 

 of thanks was extended to Mr. Holz- 

 hauer and Mr. Zimmerman. 



Professor George C. Diekman. 



In the reports of the committee on the 

 culture of medicinal plants in Austria, 

 Emanuel Senft takes up the matter of a 

 peculiar diseased condition of the leaves 

 of Datura Stramomium, during the 

 years 191 1 and 1912, and in certain 

 localities, even before this time. 



Climatic conditions cannot be held re- 

 sponsible, as these were entirely differ- 

 ent during these two years. The year 

 191 1 noted for a long continued drought, 

 while in the year 19 12, an excessive 

 quantity of moisture prevailed. During 

 the year 191 1, the leaves of this plant 

 were infested with a great number of a 

 kind of leaf louse, while in the year 191 2 

 another parasite, in the form of a red 



spider, made its appearance in great 

 numbers. Neither of these, however, 

 could be connected with the diseased 

 condition of the plant. 



It first appeared as if the leaf of the 

 plant had been destroyed by an insect. 

 In many leaves only the network of ribs 

 remained, while the parenchyma was 

 practically entirely destroyed. The dis- 

 ease, however, is caused by the depo- 

 sition of eggs by an insect on the lower 

 side of the leaf, and its gradual de- 

 struction results. Other plants affected 

 in the same manner were the following: 

 Artemisia Absinthium, Hyoscyamus 

 niger. Althaea rosae var. nigra, Carduus 

 benedictus, and others.
