 the effect of ageing is noticed in the somewhat reciprocal 

 relation of persons exhibiting all three of the venous lesions 

 and those who have none. While the cherry angioma is 

 proliferative and grows larger as time goes on the vessel walls 

 are thin and atrophic. Caviar lesions are dilated and varicose 

 veins of small size. Their enlargement may be favoured by 

 increases in pressure especially because they are not protected

 increase with ageing chiefly in relation to chronic stasis in 

 large veins, but may occur whenever the venous pressure 

 remains high. 



These observations provide a starting point for detailed 

 work on the increase in frequency, in size, and in number with 

 ageing. Nothing emerges to tell whether they are the result 

 of the intrinsic process of ageing, the mere passage of time, 

 or whether they result from the stress and strain inherent in 

 life and increase with ageing because environmental stimuli 

 accrue as time passes. Should further work help solve the
