Presentation of Early WaterColour Drawings. — Prof. 



F. W. Oliver, F.E.S., has presented five interesting and very 

 beautiful early water-colour drawings of flowers for exhibition 

 with Sir Arthur Church's collection of drawings in the North 

 Gallery (see K.B., 1916, p. 162). These drawings come from 

 the collection made by his father, the late Prof. Daniel Oliver, 

 F.R.S., for many years keeper of the Herbarium. 



Two are early works probably of the Dutch school, but the 

 artist or artists are not known ; they formed part of the Sunder- 

 land collection which was sold in 1883. 



1. Is an unfinished study of Tulips and Double Anemones. 



2. A studv of three Anemones.

The quality and tone of the paper adds greatly to the 

 charm of these two fine drawings.

* Merian, Maria Sibylla.. — Daughter of Matthew .Merian, the engraver, 

 was born at Frankfor«t-on-Maine in 1647 and died at Amsterdam in 1717. 

 She painted flowers and insects usually in water colour on vellum. Her 

 work on European insects and the plants on which they feed went through 

 several editions. Her most famous book was the folio illustration of the 

 metamorphosis of Surinam insects with the trees on which they feed, and 

 many of the plates she also engraved. She was in Surinam from 1699 to 

 1701. Her father's book, M Florilegium Renovatum et auetum," is well 

 known. Two volumes of her drawings are preserved at the British Museum. 

 Her husband, Johann Andreas Graffen, was also an artist.
