I ings, mix all well together by rubbing 

 them in a mortar, and keep the powder 

 dry. 



When the cement is wanted for use 

 take one part of the above powder and 

 twenty parts of clean iron borings or 

 filings, and blend them intimately by 

 grinding them in a mortar. 



Wet the compound with water, and 

 when brought to a convenient consistence, 

 apply it to the joint with a wooden or 

 blunt spatula. By a phiy of aftinities, 

 which those who are at all acquainted 

 with chemistry will be at no loss to com- 

 prehend, a degree of action and re-action 

 takes place among the ingredients, and 

 between them and the iron surfaces, which 

 at last causes the whole to unite as one 

 mass. 



In fact, after a time, the mixture and the 

 surfaces of the flanches become species of 

 pyrites, holding a very large j)roportion 

 of iron, all the parts of which cohere 

 strongly together. 



Blood Cement. — A cement often used 

 by coppersmiths to lay over the rivets and 

 edges of the sheets of copper in large boil- 

 ers, to serve as an additional security to 

 the joinings, and to secure cocks, <5'C, from 

 leaking, is made by mixing pounded 

 quick lime with ox's blood. 



It must be applied fresh made, as it 

 soon gets hard. If the properties of this 

 cement were duly investigated, it would 

 probably be found useful for many pur- 

 poses to which it has never yet been ap- 

 plied, as it is extremely cheap and very 

 durable. 



Flour paste. — Flour paste for cement- 

 ing is formed principally of wheaten flour, 

 boiled in water till it is of a glutinous or 

 viscid consistence. It may be prepared of 

 those ingredients simply for common pur- 

 poses; but when it is used by book bind- 

 ers, or for paper hangings, it is usual to 

 mix with the flour a fifth or sixth of its 

 weight of powdered rosin or alum, and 

 where it is wanted still more tenacious, 

 gum arabic, or any kind of size may be 

 added. 



Japanese Cement^ or Rice Glue. — 

 This elegant cement is made by mixing 

 rice flour intimately with cold water, and 

 then gently boiling it. It is beautifully 

 while, and dries almost transparent.

cement will sooner separate in their own 

 substance than at the joining, which makes 

 it useful in the preparation of curious pa- 

 per articles, as tea trays, ladies dressing 

 boxes, and other articles that require lay- 

 ers of paper to be cemented together. 



Remedij fur Burns. — Take soot from 

 a chimney where wood is burned, rub it 

 tine, and mix one part soot to three parts, 

 or nearly so, of hog's lard, fresh butler, 

 or any kind of fresli grease, that is not 

 salted; spread this upon linen or muslin, 

 or any cotton cloth, for easier and more 

 perfect adaptation. If in any extensive 

 burns or scalds, the cloth should be torn 

 into strips, before putting over the scald. 

 Let the remedy be freely and fully ap- 

 plied, so as perfectly to cover all the burn- 

 ed parts. No other application is requir- 

 ed until tlie patient is well, except to ap- 

 ply fresh applications of the soot, lard, &c.

Remedy for Whooping Cough. — We 

 have before published a very simple but 

 efiectual remedy for this disease, which is 

 again making its round. In the hope oi 

 being able to relieve some of those who 

 are sufiering, we have been induced to 

 publish the remedy, lest some may not 

 have noticed, and others forgotten it. 



Mix the expressed juice of garlick 

 with brandy or common whiskey, in the 

 proportion of half a gill of juice to half a 

 pint of brandy. 



The best way of preparing it, when 

 time will permit, is to pour the spirits on 

 whole cloves or garlick, and Jet it remain 

 several days without using. 



This preparation is to be rubbed well 

 in the spine, morning and evening. Where 

 the disease is very severe, it may be rub- 

 bed over the breast, and on the palms of 

 the hands and the soles of the feet. 



Remedy for Squinting. — I have not 

 deemed it necessary to notice squinting 

 among the diseases of the eye, the cure of 

 it being purely of a mechanical nature. 

 The best contrivance of this kind with 

 which I am acquainted consists of specta- 

 cle frames fitted with convex horn, hav- 

 ing a small aperture of the pupil, by which 

 mer.ns the squinter, if he wishes to see at 

 all, is obliged to accustom hims<*'f to
