No. 3 of the American Dental Association for Impression Compound Cakes of coii1 cnicnt sire for tu),iny impresMiins of full or pii rt i:i 1 ri t 11- tin es. Twenty-five years ago r pmplicsicd that Kerr Perfection Impression Compotiitcl would cvcmualls supplant plaster in Prosthetic Dentistry, ami our prophecy has come true The use of our compound is gaming adherents every day, who arc thoroughly ratified that it is everything wc claim. Kerr Perfection Impression Compound is superior to plaster for many reasons. An impression once taken in plaster cannot he changed There is no way known to successfully re-work plaster. This compound can he re heated changed and adjusted to any conditions. The great advantage in using Kerr Perfection Impression Compound is that the trimming of impressions is accomplished, not with a knife hut by the use of the muscles of the mouth. The impression thus conforms faithfully to actual conditions tinder which the plate will he worn. This compound softens in clear water at a temperature of 132 degrees F., also softens with dry heat. It will not warp or creep, hardens rapidly when cooled with cold water and when hard is inflexible. When soft, it conforms freely to the mov able muscles of the mouth, enabling them to trim the impression and vet press with valve-like tightness, giving relief without leak.

KERR CENTRIFICO CASTING MACHINE Permanent Crucible Illustrating Complete Equipment In order to obtain the soundest castings and the most consist cut results from centrifugal force, it must be properly applied and controlled. The Kerr Centrifico Casting Machine applies this type of lorre properly in controlled amounts. It is moliiatcd liy an oversize steel spring in the base. It utilizes a secondary arm pivoted to the mam arm. rlliis secondary arm car ries the ilaslt, keeping it in line with the easting force, as that force changes from inertia at the start to centrifugal, As a result the ntetal travels in a straight line directly into the mold; extremely dense castings are produced, the gold will not spill, and failures due to the casting marhine are eliminated. The machine is automatically operated, compact, and well constructed. Due to a unique system of cradles in the permanent crucible type, the flasks are attached to the arm in a moment; this does nw.iv with the tightening of bolts, clips, springs or catches, .1inI cliiuiii.iirs d.ingci of hurtled fingers and loss of heat from the mold '1 lie flasks ire automatically centered with the permanent fire clay crucildc, which will hold sufficient gold for any size casting without spilling The crucible is light in construction, so that it dors not draw the heat from the old. The Kerr Ceulrifico Casting Marhine fulfills every requirement. It is an effi cient easting machine, which will give long service and pay big dividends in satisfactory- dense, uniform and consistent eastings. It provides an important link in modernizing the laboratory and enables the user to get full value from the spare occupied by that laboratory, KERR l Ker CSi .ii c* For tur in c c IU\C co. i Illustrating Complete Equipment k results iront rr Cenlrifico lo im t s .

Hall Ctirnniimn Platerl KF.lUi 1/ In the progress of doing a root ranal operation, the operator often finds hiniself in need of some means of sterilizing instruments that have been used, before they can he used again. This alcohol sterilizer has for its purpose a means of keeping sterile and of resterilizing instruments that have been used so that they can be used over and over again in the same operation as long as their efficiency permits. Also of providing containers for alcohol to lie used ns a dip in the process of flaming instruments.

It is often times desirable to hate some pointed in strument that can be pushed into the canal along the side of the gutta-percha contents and bv an oscillating, rotary movement firmly press it against the side walls of the canal, leaving an opening into which an other Gutta-Percha Point can lie forced.
