684 General Notes. [ November, 
aerial internode. For this purpose he measured the growth of the 
common peduncle of the inflorescence of the hyacinth, with the following 
results in two specimens, one grown in a hyacinth-glass, the other in 
soil in a pot. 
Specimen A, grown in a hyacinth-glass. This was first measured at 
noon on February 23d, when the peduncle, with a total length of 1.25 
in., was divided into two equal portions of 0.625 in. At 10 a. m. on the 
26th, when it had increased to 1.55 in., each of the two sections was 
again divided, the length of the four portions, proceeding from above 
downwards, being 0.35, 0.4, 0.4, and 0.4 in. Measurements were made 
twice and sometimes three times a day ; and it was soon evident that the 
energy of growth of these different portions was very unequal. By ten 
P. M. on February 29th each of the three uppermost portions was still 
only 0.5 in. long, whilst the lowest had increased to 1.0 in. From t is 
time the increased rapidity of growth of the lowest portion was still 
more marked. By ten P. m. on March Sth the lengths were respectively 
0.9, 0.9, 0.85, and 2.35 in., and at ten P. mM. on March 11th, when the 
growth had finally ceased, the measurements were 1.15, 1.0, 1.0, and 
3.45 in., making a total of 6.6 in. The following is a complete table of 
the measurements : —
