In the last News-Letter I notice Mr. Urbahns’s formula for the dilu-

My laboratory tables are made of white pine, are 2 feet wide and 
6/4 inches thick when dressed. They should be made a length suitable 
the purposes for which they are to be used. They are tongued-and- 
Pooved and put together with glue as it is next to impossible to get a 
lard of that width now. There should be @ leg at @ach four corners 
ry @& short table and two in the middle if the table is long. Tnese levs 
f hard pine and 2 1/2 inches square at top and begin to taper about 
if way down the leg, At each corner where these legs attach an inch 
ad @a half hole is bored, 3/4 in. deep. The leg is then made with a 
responding offset to fit this hole, then two right-angled iron braces 
Pe screwed to the legs and the tables, which firmly and securely hold the 
@s in place. These legs can be made any convenient length. Then a nicel 
inished two-drawer cabinet (perfectly plain) 13 1/2 in, x 22 in. (insid» 
easurement), made of white pine should be made and placed on top of the 
able at one end. If it is a long table, make one for each end, This

fees while working. I put no finish whatever on the table, but. this wood

tage in that it can be quickly taken apart and shipped (when wrapped) 
B an ordinary board. I forgot to mention that there should be couple 
leats (about 3/4 in. thick) screwed crosswise of the table underneath tu 
revent any possible warping. This is the most convenient, workable table 
have seen for laboratory use, and any shop or good carpenter can easily
