![These observations were made for the first time during the five yeas of 1878—1882 and were resumed again in 1888—1889. Inborn debiUty. hydrocephalus, rachitis and scrophulosis have been made the subject of observation du- ring the said seven years, whilst the other causes of death were added only during the past two years. From the results obtained, we could in truth not con- clude, how many children issued from parents of different age have died from the different causes mentioned above, but me may well infer, how the frequency of these causes is changing with the progressive age of parents — and to know this in fact the real aim of our investigation. We shall investigate in the following, fers the influence of the maternal, then that of the paternal age and finally, which changes have i^een produced by the combined age of l^oth parents. To be sure whether the parental age exercises indeed a special influence on the appearance of uterine causes of deaths, 1 have also sulnnitted to o])servation the most important of the extrauterine order, that is the diai'rhoea; we shall regard, if it follows a different way. To avoid lieavy and tedious circumscriptions, it may he allowed to agree in the following Umns: children issued from ])areiits of tlie same age, may be shortly named ecfui- parental, children whose fathers are of the same age equi- ') In fact consumption was also already observed in tlie first }3e- riod. But in consequence of tlie ambiguity of terms tben used — tlie Hmigarian term for consinnption being like tlie Engiisb doubtful, Avbetlier it Jiip.iiis coiisiimptiiju in general — atropbia, or lung consumption ~ tubcrcolosis pulmoiunu — I jjrel'ei'ed l.o renounce entirely upon the observations of this period. But beginning from tbe year 1888 a strict distinction was introduced between inanitio — atrophia infantum and lung tuberculosis.](https://iiif.wellcomecollection.org/image/b22275411_0006.jp2/full/800%2C/0/default.jpg)
