VI PREFACE. 



gentleman I owp the elaborate table giving the "Average of 

 Meteorological Observations, extending over fifteen years." 



Mr. Francis Brent has kindly communicated stations of a few 

 of the rarer plants, and IVIr. F. H. Goulding has enabled me to 

 quote many more through the loan of his Herbarium, con- 

 taining specimens collected by the late Mr. J. Eanker and other 

 botanists of the neighbourhood. 



I am indebted to my brother, Major J. A. J. Briggs, for the 

 drawing of the map of the Botanical Districts, and also for 

 much help in the preparation of the work for passing into the 

 printer's hands. 



Many of the facts given in the "Short Sketch of the 

 Progress of Botanical Investigation " are drawn from the ex- 

 haustive and admirable Blbliotheca Cornuhiensis of Messrs. 

 Boase and Courtney. 



If this work is found a useful contribution to the scientific 

 literature of Plymouth it will be a great gratification to me. 



T. E. Archer Briggs. 

 Richmond Villa, Plymouth.
