eases and physical suffering—had we the space at command in our 
* columns. We can only refer in a brief way, to a few instnnces 
showing the necessity of sunlight to bodily vigor, health and lon¬ 
gevity, and that an exclusion of it produces certain sickness and 
death. Our medical treatises and journals are full of cases show¬ 
ing the results of both these conditions as stated. Humboldt, in the 
narrative of his voyage to the equinoctial regions, says that both 
men and women of the Chaymas, whose bodies are constantly 
inured to the effect of light, are very muscular, possessing physi¬ 
cal development remarkably perfect, and that in an observation of 
five years among many thousands of Caribs, Maysias, Mexican and 
Peruvian Indians, he did not find a single case of natural deformity. 
Sir James Wylie, in a report to the Kussian Government, stated 
that in one of the barracks at St. Petersburg, three cases of disease 
occurred on the dark or shaded side of the building for one on the 
other, though the apartments in both communicated freely with 
each other, and the discipline, diet and treatment were in every 
respect the same. 
Many cases are on record where patients have in vain been 
treated for diseases baffling medical skill, until they have been re¬ 
moved from apartments into which the direct sunlight never came, 
to those where the person could be exposed as much as possible 
to the full light of the sun; and the results following such in¬ 
stances—some of which have fallen under our own observation, 
and many of which enter into the experience of every physician 
— are so marked as to be almost miraculous. Hr. Hammond, in 
his treatise on Hygiene, says; “ The delirium and weakness which 
are by no means seldom met with in convalescents kept in dark¬ 
ness, disappear like magic when the rays of the sun are allowed to 
enter the chamber.” Hr. Forbes Winslow, in writing of the sani¬ 
tary and physiological influence of light, says : “ It is a well as¬ 
certained fact that many maladies are more susceptible of amelior¬ 
ation, if not of cure, provided the light of the sun is freely admit¬ 
ted into the rooms or wards where invalids are domiciled.” We 
may here mention an instance within our own knowledge. We 
were visiting not long ago in a neighboring city, a family who 
live in the north tenement of a double house, into which during 
the longest days of early summer the direct rays of the sun come
