The bulbs had been obtained two years previously from Spalding. 

 The parasite was found only in small quantity. In the spores and in 

 the pedicel the two usual conjugate nuclei can be observed in a 

 stained section. This seems to be the first record of a Coleospoinum 

 on the Amaryllidace* ; 1 owe the opportunity^ of seeing it to the 

 kindness of Mr. A. D. Cotton. It was collected h\ Mr. F. Glover. —

J UNCUS coMPEEssus IX S.E. YoEXSiiiEE. Xo mention is made 

 of this species in J. F. Robinson's Flora of the East Biding. 

 Mr. C. Waterfall reminds me that I so named an example of Juncus 

 that he sent me, gathered in 1010 at the edge of Hornsea Mere in 

 vice-county 61. It was a small form of this species, which some- 

 times attains the height of two feet in congenial smToundings. —

The Brown Seaweeds have a world-wide distribution, and repre- 

 sent one of the oldest groups of marine plants. They display a range 

 of vecretative and reproductive organization beyond that of any other 

 plant-series. Among them is found ever}' stage of development 

 from the short simple tilament up to the giant Macrocystis or the 

 dendroid Lessonia, and it is somewhat surprising that so compi-e- 

 hensive an evolutionary series should have failed hitherto to receive 

 adequate investigation. 



It is therefoi-e with pleasure that Dr. Chuix-h's memoir on the 

 Somatic Organization of the Fhieoi)hyce{e \\\\\ be welcomed by all 

 who are interested in the genesis of plant-structure. It is, as Avould 

 be expected, an able contribution to the theory- of the subject ; and, 

 though in appearance but a modest-looking pamphlet, it yet contains 

 compressed within its paper cover what amounts to a text-book of 

 .some 70,000 words — an epitome of the whole matter. 



It is written in the author's most condensed style ; yet it cannot 

 be described as the skeleton of a text-book ; for it is more than mere 

 bones, bein^'* meat all through, but in a most concentrated form — or, 

 let us say, tough pemmican, which, taken dry, needs an infinity of 

 chewing. " In other words, the reading of this memoir is no light 

 undertaking; nor should too much of it be read at any one sitting; 

 for so full is it of facts, details, and new ideas that the mind cannot 

 dio-est and absorb them readih\ neither the memory retain them. 

 No fio-ures relieve the austerity of the text ; the student is, however, 

 aided by frec^uent references to illustrations in the works of well- 

 known authors. 



In the present notice it is impossible to do more than indicate 

 briefly the trend of Dr. Church's argument. He claims that " the
