SCIENCE-GOSSIP. 



[May 1, 1S66. 



the Erench Marygold was a new and interesting 

 flower in the reign of Queen Elizabeth. In Bacon's 

 "Essay on Gardens," the Erench Marygold is in- 

 cluded in his list of flowers for May or June. May 

 we not, then, conclude it flourished in Shakespeare's 

 garden at New Place, where, doubtless, he ob- 

 served the habits he has so truthfully and poetically 

 described ? Eor instance : — 



The Marygold that goes to bed with the sun, and with 

 him rises weeping. 



This beautiful allusion to the sleep of plants 

 Shakespeare elsewhere completes, when he describes 

 the Marygold waking at morning : — 



And winking Marybuds begin 

 To ope their golden eyes. 



Again he sings : — 



Her eyes like Marygolds hath sheathed their light, 

 And canopied in darkness sweetly lay, 

 Till they might open to adorn the day. 



The name of French Marygold was probably given 

 to this flower in consequence of its having reached 

 England from the South of Europe through Erance. 

 It would be curious to know why our lively neigh- 

 bours gave the melancholy name of " Souci <le 

 Jardin" to this bright-looking flower ! The Mary- 

 gold is now superseded by the numerous new flowers 

 introduced into our gardens. Yet its banishment 

 may be regretted ; the Erench Marygold is rich in 

 colour, regular in form, and its scent particularly 

 refreshing when the morning dew is on the leaves. 

 In addition to these attractions, methinks, we should 

 cherish a flower that our great Shakespeare admired, 

 and sang of so poetically. S. C. 



ERONDOSE DIATOMS. 



npiIE section of Navicular Diatoms in which the 

 -*- frustules are enclosed in a gelatinous frond 

 contains six genera, of which illustrations are fur- 

 nished in the present chapter. 



Mastogloia has the valve oblong and striated, 

 with costs on the connecting membrane, rectangular 

 in the front view. The frustules are permanently 

 surrounded with mucus, forming a gelatinous layer

on moist rocks and aquatic plants, each frustulc 

 being separately involved. The illustration (fig. 108) 

 is Mastogloia Danseii x 400 diameters, one of the five 

 British species. 



Dickieia has the valve elliptic and striated, 

 without costse in the connecting membrane, also 

 rectangular in the front view. The frustules are 

 imperfectly siliceous, scattered in a membranaceous 

 leaf -like frond. Both British species are figured. 

 Dickieia nlvoides (fig. 109) x 400 diameters, and

Dickieia pinnata (fig. 110) x 400 diameters. The 

 figures of the fronds are natural size.

Colletonema has the valve oblong or sigmoid 

 and striated, of a truncated ovate form in the front 

 view. The frustules are rather irregularly arranged 

 in one or more rows, in a frond which is either

 we possess two or three other species.
