The regeneration of lost limbs in Crustaceans is a subject of 

 extreme interest, and we join with Mr. Stebbing in the desire to know 

 exactly what Mr. Sinel has himself seen. The facts do indeed as 

 nearly approach the "miraculous" as any in the domain of Natural 

 History. They hardly, however, can be considered to belong to 

 "pathology," nor can we quite join our esteemed correspondent in 

 thinking that Mr. SinePs suggestion is new. In the best monograph 

 on Crustaceans with which we are acquainted we read, respecting 

 the Cancer ruricola " which relinquishes its limbs so easily as to 

 produce the impression that they are only stuck on." " The lost 

 appendages would be renewed at the next change of skin." It would 

 seem, therefore, that there was some glimmering perception of this 

 miracle as far back as 1893. We shall be glad to publish any 

 observed facts which Mr. Sinel, Mr. Stebbing, or any other of our 

 readers, may incline to supply to us. — Ed. 



D. C. K. — The following list of rust fungi which occur in the latter 

 part of April and throughout May will assist you : — 



The ./Ecidiospores (clustercups) of Uromyces ftoa: on the Lesser 

 Celandine, and the two common field buttercups. 



The brown teleutospores of U. ficarice also occur on the Lesser 

 Celandine in April. 



The /Ecidiospores of Puccinia lapsance are formed on irregular 

 purplish spots on the leaves of the Nipplewort. 



The brown uredospores of P. suaveolens begin to appear on the 

 leaves of the common field thistle soon after their appearance. This 

 fungus has already been alluded to (see p. 50). The rapid growth of 

 the infected plants will be most noticeable in May. The large dark 

 brown uredospores of P. taraxici may be found near the end of the 

 month on the Dandelion. 



The uredospores of P. lychidnearum occur on pale yellow spots on 

 the leaves the Red Campion in April, May and June. The beautiful 

 clustercups of P. tragopogi thickly cover the leaves and stem of the 

 common Goatsbeard. 



The black-brown masses of teleutospores of P. fusca occur on the 

 leaves of the Wood Anemone. The mycelium is perennial. 



In the Moschatel parasite {P. adoxce) the black pustules of the 

 fungus maybe found in abundance in April and May. The mycelium 

 is perennial and teleutospores only are produced. 



The rust occurring on leaves of the Golden Saxifrage is the 

 P. chrysosplenii. Teleutospores only are produced. 



The teleutospores of P. buxi occur on leaves of the Box. 



Endophyllum euphorbia produces its teleutospores on the leaves 

 of the Wood Spurge, arranged " in basipetal chains, enclosed in a
