Anatomy of the Vine, 



the alburnum has regularly increased in size, no additional bars 

 have been added to the liber, nor will any change take place 

 in it during the first summer ; for the liber e was retained on 

 the 7th of August, 1829, in the description of vessels D. 



During April, 1830. — The shoot of the year before, as in 

 Jig. 50., will at this time commence opening its winter cradle 

 leaves, and the young shoots will elongate themselves. The 

 liber of the largest divisions now generally divides into two, 

 but the liber of the smaller does not : the spaces that would 

 have been left between them are immediately filled up by the 

 ever-healing hand of the close cellular texture. When the 

 liber was at the point of k, Jig,. 52., it must there have 

 divided, and the first part of the close cellular ray must 

 have immediately com- 

 menced. Surely it is 

 erroneous to give such 

 formed cellular vessels 

 the name of medulla 

 rays, when so few of 

 them can possibly di- 

 verge from the medul- 

 la, and it frequently 

 happens, as it has done 

 in the above-recited 

 instance, as at Ic 3 in 

 Jig. 52., that they have 

 no direct communica- 

 tion with the medulla, 

 and this is the case 

 with many others ; 

 therefore I think I am 

 justified in continuing 

 to call them the cel- 

 lular rays, instead of 

 either divergent or me- 

 dulla rays. 



On the 10th of July, 1830. — Part of our last year's shoot 

 (Jig. 50.), will now appear likej*%\ 53., and upon it will be 

 seen part of the present summer's shoot (fh i g), the vessels of 

 which are in every respect similar to those as described on the 

 10th of July, 1829, C ; these will therefore require no further 

 explanation, but to refer to the description of the vessels C 

 and to Jig. 51. abed of Jig. 53. is that part of the vine 

 which the gardeners call the shoot of 1829, although it is 

 partly the growth of this year, as well as of the preceding ; 

 when I haye occasion to refer to it, I shall apply the same 

 term. The vessels of a division of a collet (ab c d,Jig. 53.)
