From the following authorities is shown a variance in the melting points of the preparations used, but by a glance it may be noted that the first division of men, from numbers 1 to 10 inclusive, use paraffins of melting points very near to each other; the latter group, from 11 to 13 inclusive, employ those of the higher melting points. The former group may, therefore, be said to utilize the paraffins of lower melting points. GROUP I 1. Gersuny 36-40° C. 97-104° F. 2. Moskowicz 36-40° C. 97-104° F. 3. Parker 102° F. 4. Freeman 40° C. 104° F. 5. A. E. Comstock 107° F. 6. Walker Downie 104-108° F. 7. A. W. Morton 109° F. 8. Harmon Smith 110° F. 9. Stephen Paget 108-115° F. 10. Pfannenstiel 115° F. GROUP II 11. Brœckært 56° C. 133° F. 12. Eckstein 56-58° C. 133-136° F. 13. Karewski 57-60° C. 134-140° F. From a glance of the first group the variance of the temperature of melting points is not a great one, practically lying between 102° and 115° approximately. When we consider the actual difference in the employing practicability and the effect upon the tissue there is practically little, if any, difference. The only difference between these authorities is that some employ their preparation in liquefied form, through the application of heat, while the others employ it in the cold or semisolid form. The choice of such method, from what has already been said, should unreservedly be the employment of a paraffin in the cold or semisolid form at a mean temperature of about 110° F. This choice would fall upon any one of the paraffins used by the authorities given in Group I. The objections to the “Hart paraffins” of melting points given in Group II have been sufficiently shown in preceding paragraphs, although a few pointed objections from the various surgeons may not be out of place here to offset the claims and advocacies of those employing the preparation in liquid form at higher temperatures than 110° F. Paget says: “I am absolutely sure now that Eckstein’s paraffin is without any real advantage. It is very difficult to handle; it sets very rapidly; it causes a great deal of swelling and some inflammation, and may even produce some discoloration of the skin, and it yields no better results than does Pfannenstiel’s paraffin, which melts at 110° F.” Again he says: “The best paraffin is that which has a melting point somewhere between 108° and 115° F. When the paraffin has to stand heavy and immediate pressure, the higher melting point is preferable.”
