adheres to Ilie bark by small fibres, which transmit a 

 nourishment to it, adapted to its state. When it has 

 arrived to a certain bulk, it penetrates the rind in order 

 to come forth : at its first appearance, it bears the in- 

 folding coverings along with it, from which it is soon 

 released. However, being as yet too feeble to subsist 

 without the aliment provided by the mother, it conti- 

 nues to cleave to her ; and cannot, for a long time, be 

 separated without endangering it. 



Being lodged in the matrix, the fetus there receives 

 its first growth. It is there contained at first in minia- 

 ture, in the membraneous inclosures resembling those of 

 the egg : it shoots forth small vessels in the matrix, 

 which convey thither the nourishment necessary to pro- 

 mote its growth. When it has arrived to a certain size, 

 it bursts these inclosures, and comes into the world :. 

 sometimes these inclosiures accompany it at its issuing 

 forth. After it is produced, the little animal is not al- 

 ways able to provide for itself without the assistance of 

 the da.m : she must still furnish it with sustenance, 

 which it cannot dispense with the want of for a certain 

 time without danger. 



5. The plant is nourished by the incorporation of 

 substances received from without: these matters are 

 very heterogeneous.. Being pumped by the pores of the 

 roots, or by those of the leaves, they are conveyed into 

 the utricuLi, where they ferment and digest ; they pass 

 into the ligneous fibres, which transmit them to the 

 proper vases, where they appear under the form of a 

 juice, which is more or less coloured. The ramifica- 

 tions of the proper vases afterwards distribute them into 

 all the parts, to which, they are united by new filtra- 

 tions. 



Tubes made of a silvered blade, which are elastic* , 

 and turned spirally like a spring, accompany the ves- 

 sels which contain the sap, in their course. Being ap- 

 pointed for the purpose of respiration, these tubes in-
