of man, which it is impossible to confound with any other, ii. That 

 of a woman, by a similar odour much weaker, and resembling* the 

 perspiration of women, iii. That of the ox, a strong* odour of oxen 

 or a cow-house, or of cow-dung. iv. That of the horse, by a strong 

 odour of the perspiration of the horse or of horse-dung. v. That 

 of a ewe, by a strong odour of wool, impregnated with the per- 

 spiration of that animal, vi. That of a wether, by an odour ana- 

 logous to that of sheep, mixed with a strong odour of the goat, 

 vii. That of the dog, the odour of the transpiration of a dog. 

 viii. That of a pig, by the disagreeable odour of a piggery, ix. That 

 of a rat, by the bad odour belonging to the rat. 



The same result has been obtained with the blood of various 

 kinds of birds, and even with the blood of a frog, which gave the 

 strong odour of marshy reeds, &c, and with that of a carp, which 

 gave a principle smelling like the mucus which covers the bodies 

 of fresh water fish. 



Upon trials made to ascertain whether spots of blood could be 

 distinguished, and referred to their source, M. Barruel found, that 

 to a certain extent, a pretty sure judgment could be given, even 

 after fifteen days or more. The spotted linen is to be cut out, put 

 into a watch-glass, and being moistened with a little water, is to be 

 left for a short time at rest. When well moistened, a little con- 

 centrated sulphuric acid is to be added, and stirred about with a 

 tube, then by respiring near it, the odour may be perceived. M. Bar- 

 ruel is not sure that the distinction could be ascertained after more 

 than fifteen days, and therefore recommends legal officers to allow 

 of no delay in any intended experiments, which have to bear upon 

 cases of judicial investigation. — Ann. d' Hygiene Publique. 



26. Preparation of Hartshorn Jelly. — The following process is due 

 to M. Ferrez : four ounces of rasped hartshorn is to be steeped in 

 eight ounces of water, acidulated with sixty grains of muriatic acid 

 for ten minutes, and then washed carefully in two or three waters. 

 It is then to be boiled with fresh water for half an hour, pressed 

 through a cloth, and the liquid filtered whilst hot. This fluid is the 

 jelly, which being qualified by sugar or other ingredients and boiled 

 slightly, gives upon cooling, a perfectly clear and good jelly for the 

 table. — Jour, de Pharniacie, 1828. 



27. BraconnoVs Indelible Ink. — An account of this ink is given in 

 our last Number*, but, unfortunately, M. Braconnot has been too 

 hasty, and now finds that the ink does not deserve to be called 

 indelible. With great candour he has written to M. Gay Lussac, 

 and says, " in addressing some observations on a brown colouring 

 matter to you, I was too hasty in announcing, according to some 

 trials made in a hurry, that it might be employed advantageously
