22. New method of producing perspiration in Cholera Morbus.— 
Dr. Tribolet, of Berne, has found that the best mode of effecting 
this object, is to put the patient into an empty bathing tub in whicha 
spirit-of-wine lamp is made to burn. The tub is covered with a 
carpet so as.to concentrate the vapor which arises from the combus- 
tion. In a few minutes all the air beneath the carpet acquires a high 
temperature, and produees an abundant sweating of the patient. 
This method has been repeated at Geneva with results exactly similar 
to those of the Bernese Physican.—Idem. 
23. New Compost.—M. Simonin de Sire, a land holder near Din- 
ant, asserts that the vines of early potatoes, may, without any injury to 
e produce of the root, be mowed down immediately after the flow- 
ering, and converted into a rich compost by laying down Ist, a bed of 
earth, 2d, a thin stratum of quick lime, 3d, a thick bed of the vines, 4th, 
a stratum of lime, 5th, a layer of earth, &c. The mass ferments, but 
it ought not to be disturbed till the following spring. Nettles and all 
other weeds may be treated in the same manner.—Idem. 
24. New size for the Chain of Woven Cloth.—To prevent the 
great unhealthiness arising from the low and damp situations in whic 
weavers find it necessary to perform their work, in order to secure 
the requisite moist condition of their tissue, various methods have been 
resorted to, depending chiefly upon the deliquesence of certain salts; 
merly, sea water which contains chloride of magnesium was used, 
also urine; more recently a solution of chloride of calcium. But 
the objection to these saline ingredients is that they eventually injure 
the stuff, especially in moist weather, on which account many weav~ 
ers have renounced the use of them. 
M. Morin, a chemist of distinction, having observed that all de- 
liquescent salts have this injurious tendency, has sought for a hygro- 
metric substance which is free from this objection, and he conceives 
that he has found it in a solution of the extract of lichen. This Has 
been tried by a number of intelligent weavers, whose testimony to its 
efficacy is given in his paper. It produces no unpleasant effect 
upon the stuff, and it enables them to erect their looms in dry and 
healthy situations.
