segments, but to the limbs attached to them. The remedy I 

 proposed would have this result: medipedes and postpedes, 

 medicoxae, postcoxae, medifemora, posttibiae, &c. (Latin 

 compounds), would be introduced, instead of mesopedes, 

 metapedes, mesofemora, &c, ; all of which are Greek and 

 Latin compounds. 



Setting this objection aside, as well as that of the primary 

 distribution of the thoracic segments, it is still undeniable, 

 that this system of nomenclature, although attempted to be 

 applied, is not applicable, as it ought to be, to all the thoracic 

 appendages. If applied only to the legs and their various 

 parts, it is good ; but, when applied to the wings, we have 

 those organs which are attached not to the ^rothorax, but 

 to the 7«^50thorax; termed proalse, not 7nesa\ae; whilst, on 

 the other hand, were the system to be adhered to through- 

 out, we should be under the necessity of terming the anterior 

 or mesothoracic wings, middle wings, or mesalae. 



I shall only add that Mr. Lacon has again shown [in 

 p. 77.] his critical abilities, by calling the metatarsus of 

 Haliday the last, instead of the first or basal joint of the 

 tarsus. I am, Sir, yours, &c. — J, O. Westwood, The Grove,

The Persian Iris, the Odour of its Flowers, and the Idiosyn- 

 a-asies therewith connected, (VI. 280.) — My brother-in-law, 

 Mr. Mapleton, tells me he lately bought a root of the Persian 

 iris, and asked the man, at the same time, whether it smelled 

 sweet? " Sir," said he, " some people cannot smell it at all ; 

 but, for my part, it knocks me down : I cannot bear it, it 

 smells so strong." {_Ea:tract from a Letter from the JRexu 

 W.T. Dree, Oct,l. 1833.] 



Cyathocrinite versus Encrinite, (78.) — As Mr. Conway has, 

 in p. 78 to 80., accused me of error and misrepresentation, in 

 stating that the pelvis and part of the costals of the cyatho- 

 crinite, figured in VI. 561., have been covered by the column, 

 I beg to assure him that it is nevertheless true ; and that, 

 although he asserts it to be " a physical impossibility," yet it 

 is a real fact, as several specimens in my cabinet distinctly 

 34, prove, one of which (a frag-
