For several years I have bought the Labora- 

 tory Supplies of Marine Forms put up by 

 Mk. F. W. Wamsley, of Bridgeton, N. J., 

 and I have always found them flrst-class in 

 every respect. His exhibition specimens, so 

 far as I have seen them, are very fine, and 

 are evidence of his great skill as a prepara- 

 teur. My experience has been such as to 

 cordially recommend him to those who wish 

 either specimens for display, or material for 

 class work.
