tliey all disappear and the larger globules become trans- 

 parent and colorless. In this way the petal becomes 

 transparent. Can this be the way that colored petals 

 become transparent and can this be the chemical change 

 that the cell contents undergo ? It set me to thinking 

 that perhaps it was. At any rate the observation is in- 

 teresting and suggestive. These "oil globules" are the 

 same, that is to say have the same general character as 

 the "oil globules" in Bacillariacese (Diatomacese) but 

 differently colored, and with them are also smaller active 

 granules. The former are the representatives of ova or 

 female granules and the later are the anthozoa or male 

 granules. Can reproduction take place in the cells of 

 Weigelia also ? It will bear thought. 



Proceedings of the A. M. S. — Just as we go to press 

 (June 18), we have received Part II. of the Proceedings 

 for 1894-95. It is labeled " January " and "issued quar- 

 terly." It is now just three months since the number 

 for October, 1894, was issued (March 18). The October 

 number was five months behind time and so is the Jan- 

 uary number. The delay can hardly be due to the 

 wealth of material involved, since not a dozen articles 

 have been printed in both numbers. 



The present number contains : The Structure of the 

 Fruit in the Order Ranunculacese, by Wiegand ; Limita- 

 tion of Tuberculosis, by Alleger ; A Marker, by Prof. 

 Grage ; Laboratory Methods, by Krauss ; New Section 

 Instrument, by Bastin ; and new Cover Slip Forceps, by 

 Graylord. 



The substance of nearly all of these papers has long 

 ago been published by us. One of them, that by Dr. 

 Alleger, on Tuberculosis, was printed in full in the Jour- 

 nal and in several Brooklyn papers last year.
