means the General Manuscript Catalogue, in which all speci- 

 mens presented to the Museum are entered, unless they have 

 formed part of a collection provided with a separate Catalogue. 

 B.C. refers to the MS. Catalogue of the "Bell Collection;" 

 and W.C. refers to the MS. Wilson Catalogue. Although the 

 specimens in the " "Wilson " Collection were transferred to the 

 " Bell," it has been considered better in the case of important

When the date of the presentation of any specimen to the 

 Museum is not stated, an approximation to the date may 

 be obtained from the following general statement as to the 

 entries in the General Manuscript Catalogue : — The numbers 

 had reached to 805 in 1826, to 1216 in 1830, to 2272 in 

 1842, to 2415 in 1857, to 2467 in 1865, and to 2764 in 1886. 



The Conservator wishes here to record his thanks to the 

 Presidents and Council of the College and to the Members of 

 the Museum Committee for the hearty encouragement which 

 they have given to him throughout his work for the present 

 volume. He would be very ungrateful, too, if he were to forget 

 to mention another to whom his thanks are especially due. 

 Tentative arrangements and re-arrangements of the specimens 

 have, of course, been required ; taking down and re-mounting
