order that no one. may suppose that we shall be on hand to try 

 to have our suggestions carried out. At this writing, we do 

 not even expect to go to Ithaca. Duty now seems to call us 

 in a very different direction. Therefore let no one who wants 

 to see our suggestions protected fail to exert himself accord- 

 ingly. Additionally, as we stand ready to enter into arrange- 

 ments to help carry on tlie Society's work, it would not seem 

 quite modest for us to go and urge them. We should be ac-

 the coast clear. 



We therefore say to our subscribers, both those who belong to 

 the society and those who do not, — Whatever is done to help 

 the cause, and, incidentally, the Journal, will redound to your 

 pleasure, and to ours because it redounds to yours. To you 

 will be due the credit fur anything you can do for the cause. 

 In any event, we will do the best we can in the circumstances 

 created for us. Very few of us can create our own circumstances 

 by the intensest effort. All can make the best of what 

 comes to them.

Home-made Graduated Percolating Bottle. — At the last 

 meeting of the Oregon Pharmaceutical Association J. Preuss 

 told how^ pharmacists can construct engraved measuring bottles 

 themselves. Select an even bottomed, ground stoppered acid 

 bottle; smear the sides evenly an inch in width with a mixture 

 of white wax and a small quantity of turpentine previously 

 melted together; balance the bottle on the scales. Now take dis- 

 tilled water at 60°F. and begin graduating by using 100 cc. from 

 a 100 cc. flask as the unit, at the same time checking the liquid 

 maesure by the 100 g. weight on the scale. By observing this, 

 no discrepancy can creep in. After the liquid has come to rest, 

 mark with a scissors point the line of the lower meniscus at both 

 edges of the wax. Continue adding 100 cc. quantites, checking 

 with the weights and marking, until the desired height is 

 reached. Empty the bottle, draw the lines across the wax from 

 the points and mark the figures into the wax by using the scis-
