'A strange and futile attempt of one of the philosophers of the old cast to confirm Dame Nature's abhorrence of a

 which made it most disagreeable to drink ; but also from another hurtful Quality, viz. IShe Spirit of Bittern Salt.' The

First Edition of the collected work. It is the author's most important work, and may be said to have laid the 

 foundation of vegetable physiology. ♦ Much of his work was devoted to the study of the loss of water which plants 

 suffer by evaporation, and to the means by which the roots make good this loss. In these subjects many of his experi- 

 ments remain of fundamental importance. . . . Finding that gas could be obtained from plants by dry distillation, he 

 was led to believe that gas might be condensed or in some way changed into the substances found in plants. In thus 

 recognising that the air may be a source of food to plants, he was a forerunner of Ingenhousz and de Saussure. ... In 

 first opening the way to a correct appreciation of blood pressure, Hales's work may rank second in importance to Harvey's 

 in founding the modern science of physiology.'— i^'rancis Darwin, F.R.S. ... ^ 



' He not only exactly measured the amount of blood pressure under varying circumstances, the capacity of the heart, 

 the diameter of the blood-vessels and the like, but also by an ingenious method measured the rate of flow of blood in the 

 capillaries in the abdominal muscles and lungs of a frog.'— Sir M. Foster. 



A passage in the first volume shows him to have known in one of its aspects the important phenomenon called Osmosis 

 — completely recognised and explained only in 1877 by Wilhelm Pfeiffer.
