It is now very generally admitted, that there exists a similarity between the Sanskrit and several of the languages, which by conquest or other causes, have obtained the most extensive adoption over both ancient and modern Europe [...]. Many resemblances are evident at first sight, others are discovered by more careful investigation, and the more closely we analyse the recondite structure of the kindred tongues, the more we are surprised to find them constantly developed by the same principle. A careful inquiry into the analogy of the Sanskrit with the above mentioned European languages must, on many accounts, be considered as truly valuable. It shews the higher or lower degree of affinity by which nations, who in the remotest antiquity wandered from the land of their ancestors into Europe, are connected with the present inhabitants of India.
