Jules Cesar Savigny must always be regarded as one of those natu- 

 ralists who placed structural Entomology on its true foundation. His 

 s Memoires sur les Animaux Invertebres ' are beyond all praise. In 

 these he traced, with wonderful precision, the identity of structure 

 which exists between the parts of the mouth in haustellated and raan- 

 dibulated insects ; and showed how remarkably a set of organs might 

 be so much modified in form (in order to fit them for a change of 

 functions), as in one tribe to appear as organs of locomotion, and in 

 another as organs of manducation. These and various other equally 

 important results, could only be arrived at by a precise investigation 

 of the various structures themselves ; and we accordingly find, in the 

 plates which represent them, a series of the most beautiful figures 

 which have ever been published ; whilst the plates of annulose ani- 

 mals in the great work on Egypt (of the scientific expedition to which 

 country he was one of the most indefatigable members), are unsur- 

 passed for the drawing of the many species and details therein repre- 

 sented. Among the true insects, the orders Orthoptera, Neuroptera, 

 and Hymenoptera are illustrated in that work. The fitful changes of 

 events in France, and the subsequent blindness of Savigny himself, 

 unfortunately put a stop to the publication of his beautiful works, 

 without also the necessary descriptive text of the work. This want, 

 to a certain extent, was remedied by the publication of the text by the 

 late Professor Audouin ; but much essential matter still remains un- 

 published, w 7 hich, it is to be feared, is now entirely lost to science. 

 He was a member of the Zoological Section of the Academy of Sci- 

 ences of Paris. 



John George Children, Esq., born August, 1777, died at Halstead, 

 in Kent, on the 1st of January, 1852. He was for many years Secre- 

 tary to the Royal Society, and was a very profound and practical che- 

 mist. He gave most important assistance to Sir Humphrey Davy, in 

 prosecuting his researches on galvanism, which had such an important 

 effect on the progress of that science. He was for several years Assist- 

 ant Librarian in the Natural History Department in the British Mu- 

 seum, and was made Keeper of the Zoological Collection in 1838; and 

 it was under his direction that most important changes were effected 

 in the zoological collection, by which it has become one of the most 

 perfect, and certainly the most accessible, collections in Europe. He 

 devoted a considei-able portion of his time to the study of Entomology, 

 and formed a very large private collection of insects, as well as one 

 of the most complete entomological libraries in Europe. 



In addition to the above details, Mr. Children possessed strong
