Analysis of the leaves of the Midbernj. — M. D'Arcet (the son) sends a letter 

 upon a clieniical analysis wiiicli lie lias made of the icjivis of the mulberry. 

 The result of this analysis shows that the mulberry leaf eontains (iiur parts 

 in the 100 of azote. Jt may result I'rom this eompusiiion of mulberry 

 leaves, that silk beitig a product in a high degree su[)i»hfd wiih azote, as an 

 ingredient, mulberry leaves for the nourishment of silk wi-trms c-oidd not be 

 advantageously substituted except by other leaves which also contain azote. 

 Then, as it is not known whether other leaves contain as much azote, he 

 will, to that end, make the analysis of such other leaves as are considered 

 proper substitutes for nudbeiry leaves. 



M. Chevreul says that the presence of azote has long been known in the 

 leaves of the mull)erry, and likewise in the leaves of many other plants ; that 

 the difFerence which is said to exist between animal and vegetable substan- 

 ces, relatively to the presence of azote in the former, has always been faulty 

 — because, that if, in the mass, there existed more azote, projiortionally, in an 

 animal than in a vegetable, still there were immediate products of animals 

 which contained very little azote, and even none — while there were imme- 

 diate products of vegetables which contained much azote — and vice versa. 

 It is not then only the analysis of the vegetables which is necessary, accord- 

 ing to M. Chevrenl, but also the analysis of their immediate products — and 

 especially, to understand well what of the immediate products serve for the 

 nourishment of the silk worm — since it is well known that inseets, even 

 more than other animals, have the property of rejecting, atnong the vegetable 

 substances on which they feed, and almost as they are taken, those parts 

 which cannot serve for their nourishment, and for the preparation of the 

 secretions which the insects yield. 



M. Ardouin adds, in support of what M, Chevreul says, that there are 

 many kinds of caterpillars wiiich produce silk, and in as great quantity as the 

 silk worm, and which live on trees which cannot furnish support to the silk 

 worm. 



M. Peyen says that, according to his own experience, all the vegetables 

 upon which experiments have been made contain azote datis un principe 



continu from the extremities of the roots to the extremities of the leaves 



and even in the petals of the flowers, and principally of the stigmas. — Far-

A nosegay of fruit. — At the late grand fete at Wentworth House, there 

 was placed in the refreshment room, a bouquei de fruit ; composed of every 

 variety of grapes, prunes, peaches, nectarines, &c. five yards in circumference, 

 and valued at £600.— Garrf. Mag.
