Observations on the Climate of Penzance and the District of 

 the Land's End in Cornwall ; with an Appendix, containing 

 Meteorological Tables, and a Catalogue of the rarer indigenous 

 Plants. By John Forbes, M.D. Secretary to the R.G.S.C. and 

 Physician to the Penzance Dispensary. 8vo. pp. 70. 



This work presents much useful matter condensed into a nar- 

 row compass. From the facts collected by the author, it appears 

 evident that the temperature of Penzance is remarkable for its 

 small annual, monthly, and daily range, and for its e(|uability from 

 day to day. The mean temperature of the winter there is so high 

 as 42'', while that of summer does not exceed 57° on an average 

 of 14 years ; and the mean annual range is only 49". The lowest 

 degree to which the thermometer has fallen at Penzance during 

 the last 14 years, has been 19", and this only once.
