game, cream, milk, or oysters, preserved by 

 this method may be carried across the coiiti- j 

 nent. or siiipped to Europe, retaining their 

 freshness and purity without the use of ice or 

 any refrigerating ai)pliance, or tliey may be 

 kept at home for days and weeks, even iu the 

 hottest weather, improving in taste, besides 

 saving mucli expense iu tiie cost of ice. and 

 time and trouble in going to market. There 

 is ample testimony that these are stuliborn 

 facts. It is infallii)le in its power to preserve, 

 of great strength, and concentrated in form, 

 tasteless and unobjectionable to the palate, 

 harmless in its etfect upon the lnunan system, 

 and, finall}-, capable of almost universal and 

 simple application to such food-substances as 

 are subject to speedy decay. The food treated 

 with Rex Magnus carries no unusual or un- 

 natural taste. Its use is so simple tiiat a child 

 may direct the operation of preserving food. 

 The article to be preserved may be wrapped 

 in cloths wet in the solution, and occasionally 

 redampened. or it may be plunged into a 

 tub or jar full of the solution, and allowed to 

 remain for several hours. The powder may 

 be worked into butter at the time of making, 

 or the balls of butter may be placed in vessels 

 filled with the solution, and allowed to remain 

 for weeks and months. Dairymen have pre- 

 served butter with all the freshness and aroma 

 of the June product for six months, and Pro- 

 fessor Ilumiston has preserved eggs entirelj- 

 fresh and sweet for fourteen months at a time. 



V. THOROUGHLY ISDOIJSED. 



It has been snlijected to the most severe 

 and thorough tests, both by scientific, medical, 

 and business men. Professor Samuel W. John- 

 son of Yale College, after testing it to his 

 entire satisfaction, made a report, in which he 

 says, — 



'■ My tests of thirty-five days, in daily mean tem- 

 perature of 70°, on meats, etc., bought in open 

 market, have certainly been severe; ami I am satis- 

 fied that the different brands of Rex Magnus, The 

 Ilumiston Food-Preservative, with which I have ex- 

 perimented, Afire iiccontplished all claimed for them. 

 So far as I have yet learned, Ihey are the onl;/ prepa- 

 rations that are effectite and at the same time practi- 

 cable for domestic use. At the banquet on ' treated' 

 meats at the New-Haven House, I could not distin- 

 guish between those which had been sixteen days in 

 my laboratory and those newly taken from the refri'jer- 

 ator of the hotel. The oysters were perfectly palatable, 

 and ifresh to ray taste, and better, as it happened, 

 than those served at the same time, which were 

 recently taken from the shell. The roast beef, 

 steak, chicken, turkey, and quail were all as i/uod as 

 I hate ener eaten. I should anticipate no ill results 

 from its use, and consider it no more harmful than 

 common salt." 



Rex M.agnus is a valuable discovery, a 

 boon to agriculturists, a legitimate business 

 enterprise. It is not to be classed for a mo- 

 ment with the numerous humbugs of the past, 

 — ozone, and a host of such, tiie impossible pro- 

 jects of scheming men or the visionary dreams 

 of laboratory scientists. Professor Ilumiston 

 has devoted many j-ears to studying to assist 

 the millions to get cheap food, and, as the 

 great aid to this end, made intense application 

 and active research in the matter of antiseptics 

 alone. He perfected his process, he proved 

 his theories, he demonstrated the feasibility of 

 his methods, he enlisted his co-operators, he 

 secured the necessary capital, tiie company- 

 was organized, who bought extensive works, 

 and they commenced on a commercial basis 

 ! before they took measiu'es to inform the pul)lc 

 of this wonderful preservative. 



1 VI. A Bl'SISESS liASIS. 



This company is not seeking capital of the 

 public : they simplj' propose to manufacture 

 this preservative on a large scale, to offer it 

 for sale eventually in everj- grocery and pro- 

 vision store in the land in large or small pack- 

 ages. All classes now have an opportunity of 

 purchasing the preservative in small and in- 

 expensive packages, and of testing, each for 

 himself, its value in his own home and busi- 

 ness. There is no opportunity or design for 

 any misrepresentation or serious disappoint- 

 ment iu a fair, open transaction like this. 

 There are no territorial rights or patent li- 

 censes for sale, but every one may liave equal 

 and ample chance to use Rex Magnus. The 

 company offer, however, to suppl}' any one — 

 in case his grocer, druggist, or general store- 

 keeper hasn't it on hand — with ain- brand of 

 Rex Magnus which he ma^- desire, upon re- 

 ceipt of the price. They will prepay postage 

 charges on sample packages, which cost but^ 

 fifty cents per pound for meats, milk, and sea- 

 food, while cream and other special brands 

 cost one dollar per pound. 



VII. PUEVious faii,i:res. * 



The wretched failures by which the public 

 has heretofore been deceived hilve pretended 

 to preserve all kinds of food with the same 

 compound. — an idea which is preposterous on 

 the face of it. Meat is dirterent in character 

 and substance from sea-food, and this from 

 milk, cream, and butter, these from eggs, and 

 eggs from vegetable juices or fluid extracts 

 Professor Ilumiston has treated the subject 

 in a scientillc way. Having thoroughly- invea-
