Lincoln inscriptions." Those who have looked carefully at the exact 

 copy of the stamp will readily acknowledge that the monogram or 

 nexus which had been explained as MV or MA is still more like AN, 

 though that reading did not occur to interpreters who had no clue to 

 the meaning, but to Dr. McCaul who had noticed the use of the 

 title Antoniniana it would at once suggest itself, enabling him to 

 overcome a great difficulty and to penetrate a mystery hitherto in- 

 explicable. 



Our limited space does not permit further extracts, but we cannot 

 take leave of Mr. Lee and his very attractive and useful volume, 

 without expressing the hope that the example set by the publication 

 of illustrated catalogues of the local Museums in Newcastle-on-Tyne 

 and Caerleon, may be followed in other towns where there are col- 

 lections of ancient relics, such as York and Bath, each of which 

 could supply not only ample materials for a valuable volume, but also 

 highly qualified editors, as their respective antiquities have been 

 successfully investigated by the Rev. John Kenrick and the Rev.

SCIENTIFIC AND LITERARY NOTES. 



ON THE TRANSFORMATION OF ENTOZOA. BY P. J. VAN BENEDEN. 



The following abstract taken from the "Annals and Magazine of Natural 

 History," will fulfil our promise of laying before our readers the discussion 

 arising out of a paper of MM. Pouchet and Verrier. This paper " called forth 

 from Professor Van Beneden a letter, the chief points of which are as follow : — 



" He first states that MM. Pouchet and Verrier are in error in supposing that 

 he regarded Ccenurus cerebralis as the scolex of Tcenia serrata; he has described 

 the Tape-worm produced by Ccenurus as a distinct species, under the name of 

 T. ccenurus, and that produced by the Cysticercus pisiformis of the Rabbit as 

 Toenia serrata. He ascribes the doubts of MM. Pouchet and Verrier to their 

 having failed to distinguish these two species of Tape-worms. He does not, 

 however, attempt to explain the main point dwelt upon by the French authors, 

 namely, the presence in the intestines of the dogs of a much larger number of 

 Tape-worms than that of the heads of Ccenurus, but expresses a hope that, by 

 the continuation of their experiments, those gentlemen themselves will be able 

 to clear up the mystery. 



" Referring to the failure of MM. Pouchet and Verrier in producing staggers 

 in sheep by the administration of mature ova of Taenia serrata, he shows that in 

 experiments made simultaneously at Louvain, Giessen, and Copenhagen, with 

 ova obtained from a single dog which had been fed with Coenuri, precisely the 

 same phenomena were produced nearly after the same lapse of time. In all
